How not to get faster

There’s a very well known cycling quote, posted to the Facebook walls, Pinterest boards and tumblrs of cyclists (my own included) that goes like this, “It doesn’t get any easier; you just go faster.”  It’s by Greg LeMond. (Born in 1961, LeMond is, according to Wikipedia, “an American former professional road racing cyclist, entrepreneur, and anti-doping advocate. He was World Champion in 1983 and 1989, and is a three-time winner of the Tour de France.” So he knows what he’s talking about when it comes to getting fast.

But today I want to talk about the other side of the easier-faster coin. It’s much less celebrated and and likely wouldn’t be a fave quote on Facebook walls. It goes like this, “If it is just getting easier, you’re not getting faster.” Let me explain.

I’m often asked by beginning cyclist friends what they need to do to get faster. My glib response is, ride faster. And though that might sound obvious, it’s also true.

The advice I’m about to dish out here goes beyond my tips for beginning riders who want to go faster. And it’s advice that I know to be true and sometimes need to follow myself!

The thing is I’ve known lots of cyclists, me included, who when left to their own devices go out and ride 20-40 km at a speed that feels good to them several times a week. They then wonder why after months of doing this they aren’t getting faster.  The answer is that what you’re training by doing that is your ability to go out and ride 20-40 km at a comfortable speed. You won’t get faster but it will get easier. And easier doesn’t translate into speed gains.

Because really it shouldn’t get easier. You should keep pushing yourself. You need to push yourself. You need subsequent rides to be as hard as the first.

That’s a bit of an overstatement but the basic idea is right. Don’t spend too much time enjoying your new found comfortable speed/distance. Push on.

This is something that puzzled me back when I was a beginning runner. I spent awhile at a plateau where running got easier (my heart rate slowed down, I was less wiped out afterwards) but I wasn’t getting any faster. The thing is I didn’t want to go “back” to that out of breath, exhausted feeling of my early days as a runner.

It was humbling to learn that that was exactly what I needed to do (some of the time at least) if I wanted to make speed gains.

How do you do that? Here’s two ideas:

1. By adding fast intervals. Step out of your “ride for coffee with friends” mode and engage in bike specific speed training. There isn’t anything wrong with riding at a comfortable speed. We all do it lots when we ride socially but it isn’t training.

2. Don’t spend all your time riding with friends who ride at your pace or who are nice to you! Spend some of the time riding with people faster than you. Guest blogger Catherine Womack wrote about conquering her fear of returning to group rides and I’ve written about riding with friends of different speeds as one way to mix it up.

I need to do both of these things and rejoining a bike club with group rides and doing some bike specific speed training are on my agenda for next year.

Strength Training “Tips” for Women Perpetuate Stereotypes that Contribute to the Gym as Boys’ Club

The 120 tips on strength training for women first came across my FB newsfeed yesterday morning. It looked like it might be useful post for me, a women interested in strength training. In fact, his intended audience is other trainers who are training women. That, I must say, is a scary thought, considering how consistently the list fails to take seriously the idea of women and strength training.

I started to read the post, written by “The Glute Guy,” Bret Contreras (whose blog and post I am of two minds about bringing further attention to, but it has to be seen to be believed).  My hackles went up immediately, before I even got to the list, because it started with a disclaimer.  Many of the things in the lists aren’t actually “tips,” he said, more like “observations.” And then comes the old “please understand that I intend no disrespect or offense, I’m not trying to be controversial” disclaimer.

I’m sorry but when I read that kind of thing, I just hunker down and prepare to be offended.

The first 1-13 are “exercise considerations,” like that “proper push-up form is more difficult to attain for women than it is for men” (okay, I think we all know this, but where’s my “tip”?) and “some women have ‘coregasms’ when training, and the hanging leg raise is the primary culprit (these orgasms usually aren’t welcomed as they’re inconvenient).” Wowza! That’s the closest thing to a tip in the first section — do some hanging leg raises if you can catch some private time at the gym.

I really started to shift in my seat when I got to the part that generalized about women’s “fortitude and dedication.”  He says, “many women lack the fortitude and dedication to ever see incredible results from lifting due to ‘being a lifter’ rather than ‘being a student of weight lifting'”.  As the fabulous Jezebel post (author: Laura Beck) today commented on this point, “what?”

There are lots of “tips” about what women need to be taught, what they will insist on doing “if you let them,” and what sorts of second rate measures they will “resort to” if they are not adequately coached by their trainer.  I can just imagine the mansplaining that must go on in this dude’s sessions with his female clients.

In the comments, one commentator (Samantha — not sure if it’s the Sam B), notes that many women are newbies to weight training. She points out that men are often exposed to weight training earlier, by friends or family or in school.  A newbie is a newbie —  man or woman, you will need some instruction to be able to strength train safely and effectively.

After a while, it just gets ridiculous, as in this sequence from number 26-40:

  • Women differ psychologically compared to men (for example they’re motivated to train uniquely, and what revs up a man to max out doesn’t necessarily rev up a woman to max out)
  • It is common for women to miss periods (menstrual cycles) upon embarking on an intensive training regimen (not to be confused with amenorrhea which happens when body fat drops too low)
  • Menstrual cycles usually have a huge influence on factors such as training motivation, irritability/mood, water retention, and self-esteem during exercise
  • The size of women’s breasts and also butts can fluctuate markedly throughout the month, which can lead to frustration
  • Some women experience urinary incontinence when exercising, and the likelihood increases after giving birth
  • Woman are better than men at fostering camaraderie but not quite as good as men at holding training partners accountable for showing up
  • Many women don’t activate their pelvic floor muscles properly
  • Women tend to prefer different training music than men
  • More women than men like to offer up the phrase “they say” as proof of evidence (who exactly is “they”?)
  • Most women don’t like getting weighed on scales, and many prefer to see how clothes fit as measures of progress (I don’t agree with this practice as I like to utilize all measures of progress)
  • Women like wearing pink workout apparel and take their training attire much more seriously than men (for example they tend to match their shoes with their shorts or shirts, etc.)
  • Women love putting chalk on their hands and then clapping hard – thereby getting chalk everywhere rather than keeping it solely on the hands (they probably do this because they saw gymnasts do it)
  • Women are not as natural as men at adjusting machines and apparatuses
  • Women love compliments – it fuels their fire to train even harder

We have a couple of things in feminist analysis that we tend to come down fairly hard on:  gender stereotyping and gender essentialism.

Stereotypes of women paint a particular kind of generalized picture of them that often makes them seem less serious than men. The suggestion that women wear lots of pink (not sure how this “tip” will help me or my trainer) or that they have bad chalk etiquette (from emulating those darn gymnasts!) or that they are “not as natural as men at adjusting machines and apparatuses” (you know how women are with anything technical and mechanical) perpetuate stereotypes about women that insinuate that they have no place in the gym.

And if women would stay out of the gym, then there would be no conflicts about what training music to play over the speakers.

Gender essentialism with respect to women suggests that there are some essential biological features of women that identify them as women. The comments about menstruation and the fluctuation of breasts size and butt (?? really ??) size, suggests, among other things, that women are inevitable victims of their essential biology.

Apparently, according to Bret’s observations, women aren’t into science and research. No, women are satisfied with anecdotes (like Bret’s 120 anecdotal observations about strength training for women), maybe anecdotes based on what “they say” (see tip #34 in the grouping, “Anatomical, Physiological, Psychological, and Random Considerations.”

He gets a few things right. For example, “Women usually don’t want to be bothered in the gym – unsolicited advice from meatheads and cheesy pick-up lines get old quickly, yet men will nevertheless remain persistent.” Hallelujah!  It’s sad that this is buried among  crazy generalizations about the way women dress sexy and then get upset when men show an interest, undervalue their training partners, and make sexual sounding grunts (whereas, says Bret, men’s grunting isn’t sexual-sounding.  Um, okay. Maybe that’s what they say, but I have heard differently, if you know what I mean).

This list is disturbing on many levels. Gender stereotyping and essentialism are both pernicious social forces that help keep patriarchal power structures in place.  The list is full of them, thus reinforcing the notion that women don’t really belong in the testosterone-heavy space that is the weight room.  What’s more disturbing is that the list has been compiled by a trainer who trains women yet fails to take them very seriously in their aspirations.

He is more busy observing how much pink they wear (might be useful to do some analysis on how many non-pink options are even available to women) or how fickle women can be: “Some women seem impossible with their complaints; for example one day they’re worried about getting too bulky and the next day they’re upset that they lost muscle size somewhere.”  Silly women, can’t make up their minds what they want. Maybe they’re on their period and still reeling from the fluctuation in the size of their butt that month.

It’s more disturbing still that his intended audience is other trainers. Some have even confirmed his “findings” in the comments.  But this all goes to the stereotypes.  With this list of stereotypes out there, this could become the default frame through which women in the gym are viewed by unreflective trainers (who just listen to what “they” say). Women are portrayed as giggling, incontinent, know-nothings who “during casual conversation, when most women imitate weight lifting form to friends, family members, or peers, all of a sudden they get the form all wrong (for example they’ll imitate a deadlift like an upright row).”

It’s astonishing how a dude can do something that looks at first to be woman-friendly, namely, post a list of tips for strength training women, and have it go so horribly sideways by perpetuating stereotypes that actually secure his view that the gym is and ought to be a male domain.  He had an opportunity to empower women and celebrate the fact that more and more women are owning their strength and working out with heavy weights. But he didn’t take it.

Lots of women are informed and educated about what they do in the weight room.  They have a right to be taken seriously by their trainers and by others working out along side them. This tipsheet does more damage than good to the women who have claimed and are yet to claim their place at the gym.

End of rant.

Six reasons not to race and why they might be mistaken

I love racing, even though I’m a midlife, middle of the pack athlete. I know this puzzles some people (okay, some of my friends) and I often find myself in the situation of responding to the objections to racing that they raise.

Some of my friends are not at all interested in competition but I worry that their reasons are based on some misconceptions about why those of us who do race enjoy it.

I often think the anti-racing crowd might like it too.

So here’s my attempt to respond to the race-shy or the race-skeptical.

1. Some friends say, ‘I’ll never win so why race?’

Note first that this is true for lots of athletes. Think of how many riders there are in the Tour de France and how few are serious contenders for even winning one of the stages, let alone the overall race. Think about the numbers of people in the Hawaii Ironman. They aren’t all contenders for the podium, even in the age group categories. I’ve only won two races in my lifetime but I love the ‘winning moments’–passing someone even if I can’t hold them off, for example. In bike racing I love being part of the team effort, participating in strategies that get one of my team’s riders into the front pack.

2. Some friends say “I’m only interested in fitness.”

I get that but to be fit you have to push yourself and trust me, you’ll never ever push yourself as hard in training as you do when racing. I wear a heart rate monitor when training on the bike and I’ve done VO2 max testing so I’ve got some idea of what the various sports training zones mean for me. I’ve also worn the heart rate monitor when criterium racing. The first time I did this and then looked at the data after I laughed out loud at how much time I’d spent in the red zone, E4. That’s something I just can’t make myself do for very long outside race situations. I won’t bore you with all the geeky gory details but here’s the my HR data from a crit last year: Avg HR 171, max HR 178 (32% in E4) Avg speed 33.2, max speed 42. No way I could do that outside a race.

3.  Some friends say, “I just want to train, not race.”

Okay, but it helps to have a focus for your training, something to train for. Races give structure to your training as you build endurance, then speed, then both together, taper off coming up to the race, race, recover, and rebuild.

4.  Some friends say, “I’m too old.”

These friends admit they might have enjoyed racing in their youth but now they are too old, they think. They’ve grown up and put all the fun away. To which I say, don’t be ridiculous. It’s like saying that sex is for the young.  We’ve only got one kick at the can, one try at this life, and if something would have been fun when you were young, it’s probably still fun now. (Like sex.) The Vets Racing Club in Canberra requires a doctor’s notes in order to keep racing after age 75 and there are people in that category.

5.  Some friends say, “I might get hurt.”

Yes, that’s true you might. You also might get hurt sitting on your sofa for too long, or shoveling snow. Life is risky, no way around it. But in the category of recreational racing most people recognize that we aren’t professional athletes and there’s no sense risking injury unnecessarily. Some of the rules in masters and recreational racing reflect this. On the one dodgy corner on the crit racing course in Canberra–“collarbone corner” as it’s known–race organizers decided not to allow passing through that bend. For that one short turn the race is “neutralized” and riders are asked to hold their place. I also love the reminder that the race organizer gives riders before the start, “Remember we’re not racing for sheep stations out there.” In other words, we’re out there for fun not fortunes. (See image above.)

6. Some friends say, “I’m just doing this for fun.”

Racing is a lot of fun. Whether you most enjoy the training, being out there competing, or the music, snacks and prizes after, at the level of recreational athletics it’s all about the fun.

Hope to see you out there!!!

Aikido

Aikido and training to test

Tis the season!

No, not that season. It’s testing season in my Aikido Club.

There are lots of martial arts clubs where everyone tests every time there is a test and where, if you put in the years, you’re assured of a black belt. Aikido is not one of those martial arts.

Many people train for years at the same belt level and the size of the jump, that is the amount of training required, between each belt goes up with the belt levels. So it might make sense in terms of your commitment to Aikido to stop after say, your brown belt.

Everyone begins wearing a white belt and your first test is for 9th kyu–white. You can see the list of belt levels and what’s required here, http://www.aikido.on.ca/_docs/Yoshinkan_Aikido_Kyu_Test_Syllabus_2012.pdf.

December 22 is the next Aikido belt test. If I get to test, I’ll be testing for my green belt, 5th kyu. I say “if” because in our club, people are invited to test. We all train as if we are going to test and then those who are judged to be ready to test are invited to take part in testing.

The idea is the gentle one that no one tests who isn’t ready. If you’re invited to test it’s because people have judged you ready to do so. This makes the actual test day less nerve wracking but it also spreads out the anxiety over a period of weeks before the test as you know that the senior belts are watching you train.

On my next test, whenever that is, I’ll be examined on all the basic movements of Aikido (done with partner) and on six new (to me) techniques. Here are the techniques on my test:

Why are painful workouts so much fun? (And other questions about suffering and athletic performance)

What makes painful workouts so much fun? Or assuming there’s some self selection at work here, we could ask the question a little bit differently: Why do athletes find painful workouts so much fun?

Now not all of the workouts I do are painful. Most days of the week I workout out twice a day and I wouldn’t be able to take that kind of intensity all the time. Nor does it make sense from a training point of view. But still the best workouts, the ones that are the most fun, are the painful ones. And as philosopher, I find this appreciation for pain more than a little puzzling.

But let me begin by describing two of the painful workouts I’ve done this week.

Here’s Monday’s Crossfit workout: The snatch ladder (be mature, no sexual jokes please, we’re all grown ups here)

The snatch ladder from the Crossfit Games looks like this

30 Snatch (M 75 / F 45 lbs)
30 Snatch (M 135 / F 75 lbs)
30 Snatch (M 165 / F 100 lbs)
Max Rep Snatch (M 210 / F 120 lbs)

“This workout begins from the standing position. The athlete will complete all reps at the first weight before advancing to the next weight. Score is total reps completed in 10min.”

We tried this event as our workout of the day on Monday. I’ve got to say it was 10 min of torture. Yet, lots of us loved it and therein lies in the puzzle.

Tuesday’s rowing workout was more painful though and more fun. Rowing workouts are notoriously tough. A friend regularly does something she calls “the erg of death.” I get that.

Though I’m new to the rowing world, cycling workouts are much the same. The best series of cycling training videos, for indoor workouts on the trainer or the rollers, is called The Sufferfest.

Gallows humour about throwing up and passing out is routine. Like the Crossfit tshirt says, “Yes, you will pass out before you die.” And we all know the sayings: Pain is weakness leaving the body. What doesn’t kill you…etc etc etc.

The rowing torture took place on the erg at the London Rowing Club. Here’s the drill: 2000 m for time, rest 3 min, 1500 m for time, rest 3 min, 1000 m for time, rest 3 min, 500 m for time. Collapse on the floor gasping a mere shadow of your former self. Crawl to car, drive home.

I won’t bore you with all the gory details but I did manage the final 500 in 1 minutes and 56 seconds. I was very happy that I finished faster than I started even after all that effort. But I had nothing left in the tank at the end. My legs were screaming for those final 200 m and I was gasping for air. It helped that I had a coach and some other rowers who’d finished ahead of me cheering me on but still that last bit of our workout really hurt.

And I loved it.

So here are some questions about pain and athletic training and performance I’ll be talking about in the coming weeks. Here I just want to raise the questions. Later I hope to say more about them. In the future I’d like to write a philosophical paper on pain in the context of sports training.

1. Are athletes masochists? Now before we all snicker, let me say I don’t mean sexual masochists necessarily. Sexual masochists take sexual pleasure from pain delivered in a sexual context. But you needn’t find sexual pleasure in pain to find pain enjoyable.

Here’s Lance Armstrong:

“Cycling is so hard, the suffering is so intense, that it’s absolutely cleansing. The pain is so deep and strong that a curtain descends over your brain… Once, someone asked me what pleasure I took in riding for so long. ’Pleasure?’ I said. ’I don’t understand the question.’ I didn’t do it for pleasure, I did it for pain.”

And my former track session leader at the Forest City Velodrome used to run from one corner of the track to the other yelling “suffer” as we did 500 m efforts.

2. Are we right to use the language of pain and suffering here at all? While some of us relish talking this way–guilty as charged–others are put off by talk of how much the efforts hurt. They find it demoralizing. As with childbirth (another kind of pain with which I’m intimately familiar) some athletes prefer to talk about intense sensations rather than about pain.

“Wow, that was an intense workout.”

And it’s true that athletic pain from effort is different from pain from injury. It’s not like someone is chopping your arm off without anesthesia. I’ve often compared childbirth which I’ve experienced three times, all without pain relief, to the pain of athletic effort. And I do tell friends that if you’re familiar with that sort of pain, childbirth will be, to that extent, familiar.

I’m not even sure I’d erase the pain, if I could magically do that without drugs, from the experience of childbirth. It felt like an accomplishment much the same way that finishing an endurance sporting event does.

3. Cyclists sometimes say that the person who can suffer the most will win the race. The ability to suffer, to take it, is highly valued. It’s a fascinating question I think, the psychological limits of our ability withstand great suffering.

Consider the article The Transcendent Pain from Bicycling Magazine: “In which we dig deep into the history and the latest research of the revered art of suffering and discover some good news: You can always go harder. Or is that the bad news?”

4. Athletes are known to have high pain tolerances and medical researchers have sometimes wondered what makes athletes different. Is it just self selection (people who don’t like pain quit sports) or is there something more? Can the ability to tolerate pain be learned?

From the journal Pain, “Higher pain tolerance in athletes may hold clues for pain management,”  http://www.eurekalert.org/pub_releases/2012-05/ehs-hpt051512.php.

5. What tricks or techniques do athletes use to push through the pain?

“Your mindset plays a huge part in your ability to tolerate pain. If you want to be a competitive cyclist, you have to know how to go deep into the pain cave.  A cyclist’s ability to suffer often determines who steps onto the podium and who is standing off to the side. Whether you’re climbing a 10% grade, bridging a gap, or sprinting for the finish, there will be times when you need to dig deep and go harder than you ever thought possible – so how do you it? “I’ll tell you what racing’s about. It’s about suffering. It’s about pain – racing hurts.” Andrew Juskaitis.”

In the article “Suffering: Preparing to Push Yourself through a Hard Effort,” in the journal Podium details a variety of methods cyclists use to cope with pain.

I’ve tried some of them–counting to 20 before I’m allowing to downshift when climbing, for example–but others are new to me. I thought I’d try some out and report back.

6. Finally, what does it mean to talk about the ‘good pain’ of a really tough workout? I gave a talk on gender and cycling at the Trent University and some audience members were genuinely puzzled, claiming never to have experienced anything they’d call a good pain. All the athletes in the audience though knew exactly what I meant. I think for another blog post I’ll try to answer that question. Wish me luck!

Is it time to ditch exercise?

Exercising, working out, or training? I almost never use the first of these terms and I have a strong preference for the 3rd. Here’s some thoughts about why.

Recently the media reported on a study from the University of Alberta that showed shows like The  Biggest Loser put people off exercise with its extreme depiction of what exercise involves.

From the U of A website: Researchers in the Faculty of Physical Education and Recreation found that watching a short video clip of The Biggest Loser fueled negative attitudes toward exercise, raising further questions about how physical activity is shown in the popular media.

“The depictions of exercise on shows like The Biggest Loser are really negative,” said lead author Tanya Berry, Canada Research Chair in Physical Activity Promotion. “People are screaming and crying and throwing up, and if you’re not a regular exerciser you might think this is what exercise is—that it’s this horrible experience where you have to push yourself to the extremes and the limits, which is completely wrong.”

Read more about this here.

For me, the word ‘exercise’ has negative connotations, even without The Biggest Loser. At best it sounds dull and joyless. I use the word to describe physio rehab that I do. Those are exercises but that’s about it.

I’ve been active a lot this weekend but, physio aside, none of it has been something I’d call exercise. Saturday mornings I go to Aikido where I practice and I train. The emphasis is on skill development and training seems to me to be the right word. True, I got really hot and sweaty during hajime training but getting hot and sweaty wasn’t the point. Moving fast, without thinking, putting the techniques in ‘body memory’ was.

Saturday afternoon I had a soccer game. We lost against the Chocolate Martinis. (An aside: I think nothing screams ‘middle aged women playing soccer’ quite like the team names. Last week we won against Cougartown.) Was that exercise? I ran fast and played hard but I wouldn’t describe what I was doing as exercise. I was playing. We were competing. Yes, it’s a recreational league but we do play to win. In the end we lost but we had a lot of fun.

And Sunday morning I’ll be at the rowing club for an early morning erg session. Again, there’s a lot of technique involved and I think of it as training, not exercise per se. For example, we did a really challenging drill Thursday night trying to match a pace slightly above our 2 km test pace but with a much slower stroke rate. Tough work and really hard to concentrate on technique. Usually my bike ride home from rowing is much slower than my pace on the way there.

Most weekends I also take my dog out for a 5 km + hike in the woods. Usually we run together. I love being outside and I like the feeling of running on trails in the woods.

So Aikido, soccer, rowing, bike riding, and dog-jogging. But no exercise?

I’d say in one sense that’s right. I do these things because they’re fun, a big part of what I think of as the good life. I spend a lot of time as an academic in my head, with words, books, and ideas but being physical really matters. It’s a key part of who I am.

No wonder inactive people are put off by The Biggest Loser’s participants. Those people are not having any fun. It’s joyless. They are exercising for one reason and one reason only, to lose weight. If that were my reason, I’d have quit a long time ago.

My advice to people who want to be more active is to find something you love, something you enjoy, something you’d do anyway even if you didn’t lose weight. We need to experience more joy in our lives, joy in moving our bodies in ways that feel good.

For you, that might be dance, yoga, walking, or gardening.

For me, I’m a competitive person and I like races and games with winners and losers. I also like skill development and getting better at something, like testing for new belts in Aikido, crit interval drills on the bike, or learning the technique involved in rowing.

It’s clear with cycling, the sport I love best, that it’s not medicinal exercise, taken in daily doses for health related reasons. Instead, at various times I’ve trained and raced. These days more often I ride for fun with friends. I also often commute on my bike and use it for practical transportation.

Even Crossfit–the one thing I do to which the term ‘workout’ really applies–has both a skill building (weight training, Olympic lifting) and a competitive element. It’s ‘as many reps as possible’ or ‘so many reps for time.’ I usually focus on competing with myself but other people there seriously train for the Crossfit games.

If exercise, as a term, works for you, great. But for many of us it misses the mark.  For us, let’s ditch talk of exercise and talk instead about all the fun physical activities that are part of the good life. I think sharing the joy in physical activity is a better route to getting more people moving than in prescribing exercise in medicinal doses.
