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.”

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.

Science, exercise, and weight loss: when our bodies scheme against us

I love it (okay, not really, need sarcasm font) when people suggest to me that to lose weight, I should get a bit of exercise, you know, walk more, or take the stairs instead of the elevator. When I tried Weight Watchers for the very last time they gave handy hints like getting off the bus one stop early and walking to your destination. (Um, I ride my bike to work most days. I ride hundreds of kilometers a week, in addition, for fun when the weather is good. How does that fit in?)

Of course, this advice is always from well-meaning people who don’t know me. Those who know me, know that I work out at a variety of sports and physical activities most days of the week, often twice a day. I run, ride my bike, play soccer, lift weights, practice Aikido, and most recently have taken up Crossfit. And yet, I’m very overweight. Fat, big, call it what you will.

How on earth can this be? Newcomers to cycling sometimes say “Oh keep riding the bike and you’ll lose weight,” thinking I’m new too. (I like passing those people, zoom!) Sometimes I’m aware I actually put other fat women off exercise because they are starting to exercise in order to lose weight and then they see me, and think it’s all pointless. But I don’t exercise to lose weight. My experience tells me that, on its own, it doesn’t do very much.

So why doesn’t exercise help with weight loss? (Or to put the question precisely, why doesn’t it help as much as it seems it ought to, when you consider the calories burned in our efforts at fitness?) Given my interests and personality type–geek, academic, fitness buff–I’ve read rather a  lot about this question.

There are a number of different answers.

The first answer is simple and it’s probably that first thing that came to your mind: when we exercise, we eat more. Indeed, if you care about performance and recovery, you need and ought to eat more. I was once told by a cycling coach that it’s foolish to try to lose weight during the racing season. Not eating enough–which is what you need to do to lose weight–cuts your speed and your recovery. Diet in the off season when you’re just riding for fun, he said. Don’t hurt your performance by dieting.

But there’s another answer that I find intriguing. Our bodies’ efforts at maintaining weight are ingenious. It turns out that when we exercise more, we also move less the rest of the day. This isn’t intentional. It isn’t anything we decide to do. The idea is that our bodies decide for us.

I’m interested, and fascinated by, the way our bodies undercut our best efforts. Heavy exercisers, it turns out, often move less the rest of the day and so burn not that many more calories than if they hadn’t exercised at all. When not exercising, they’re chronic sitters!

The study which sets out to prove this is cited in the Gretchen Reynolds’ book The First 20 Minutes  and she writes about it in her New York Times Phys Ed blog too. Following a group of young men assigned to a heavy exercise program, researchers were surprised at how little weight they lost. Yes, they ate more but more surprisingly, “They also were resolutely inactive in the hours outside of exercise, the motion sensors show. When they weren’t working out, they were, for the most part, sitting. “I think they were fatigued,” Mr. Rosenkilde says.”

Some people say we ought to “listen to our bodies.” But in my experience our bodies are sneaky experts at staying the same size. They need to be ready for feasts and famines and those women with extra body fat are more reproductively successful.

It’s another argument in favour of short, sharp, intense Crossfit style workouts since they don’t seem to have this effect. Once again, it’s High Intensity Interval Training (HIT) for the win. Thirty minutes, says Reynolds, is the sweet spot for exercise.

And it’s yet one more argument against sitting.

Some personal observations:

  • In the past I’ve been a big fan of the hard exercise followed by flopping! It’s when I write best, physically exhausted and mentally alert. Without exercise, I’m a big fidgeter and pacer in a career that rewards focus, concentration, and long bouts of sitting. Now I’m working at a standing desk (at home anyway) and I’m liking the change. I’m also trying to incorporate more movement throughout my day. 
  • This puts me in a mind of a discussion members of my bike club used to have about our long Saturday morning rides. Some of us thought we ought to have shorter routes, say 100 km rather than 150 km, not because we couldn’t ride 150 km but rather because we wanted to do things with our families afterwards. The extra kilometers tipped us past the point where much was possible after other than a nap, a bath, and lounging about the house. It seemed all wrong to come home and then tell the kids that I couldn’t go to the park, go for a bike ride (yikes!), or walk the dog because I was too tired from all the bike riding!
  • While exercising itself doesn’t make much difference, changing your body composition does. A body with more muscle burns more calories throughout the day and so there’s good reasons to lift heavy weights. I know lots of women do long, slow cardio to lose weight (you know, the “fat loss” button on the exercise machine at the gym) but science says they ought to be lifting weights instead to get lean.
  • In terms of appetite, I think HIT is right on. Long, slow runs and bike rides make me famished. I can control what I eat after but it takes tremendous effort. Endurance exercise makes me hungry, whereas intense efforts have just the opposite effect.
  • Of course, why listen to a big person talk about exercise and weight loss? The truth is I’m terrific at weight loss. I’ve lost 50-70 lbs quite a few times. I’m a failure at maintaining the new lower weight, but that’s a puzzle for another time.

Is Aging a Lifestyle Choice?

I’ve been reading, and really enjoying, Gretchen Reynolds’ book on exercise science, The First Twenty Minutes: Surprising Science Reveals How We Can: Exercise Better, Train Smarter, Live Longer.

Lots of it is fun but for those of us who follow exercise science in the media not really news.  I read Reynolds’ Phys Ed column in the New York Times and lots of the chapters cover in more detail, and with footnotes and references, material covered there. That’s fine. Nice to have it all in one place. High Intensity Interval Training beats out long, slow workouts. Yep. Chocolate milk is a better recovery drink than Gatorade. Yep. Exercise doesn’t help (much) in the quest to lose weight. Yep. Sad but true. OK, it gets worse. Massage after exercise–a cyclist’s favourite thing–doesn’t actually increase blood flow to muscles or help remove lactic acid to aid recovery. (Read about that sad result here, http://well.blogs.nytimes.com/2010/06/02/phys-ed-does-massage-help-after-exercise/.) Still feels wonderful though so I’m sticking with that one. Science be damned.

But the chapter that is still rattling around in my brain is the one on exercise and aging. My blog title is the controversial way of posing the question Reynolds asks in less bold terms. What exactly is the connection between exercise and aging? The old view was that muscle loss and a decline in aerobic  capacity were inevitable with old age. We slow down with age and become more frail, starting in our 40s, it seemed. But new research suggests the connections may run the other way. We become slower and more frail because we stop moving. Older athletes get slower and less strong, not because they’re older, but rather because they train less than younger athletes.

We age because we stop moving, on this way of thinking about the connection. It’s as if aging is something we choose to do. That’s a very intriguing idea. What’s positive about this is we could choose differently. We could choose to keep moving and avoid some of the physical decline we associate with old age. But what’s less clear is why older people slow down and take to their rockers. It may be that the psychological urge to rest is stronger than Reynolds and the researchers think. If aging brains are the problem, then slowing with age still might be inevitable.

I got a taste of the ‘use it or lose it’ idea this week when I went to physio for my injured shoulder. In addition to a host of exercises, I was complimented for getting right back to Aikido, Crossfit, etc. I shared with the physio dude the worry of friends and relatives that I ought to slow down while my shoulder healed, maybe even take time off lifting weights and doing martial arts. Yeah, he replied, lots of people think that and then they never regain the range of motion they had and it gets harder to go back to your usual physical activities. Keep moving, he said, echoing Reynolds.
