I understand the article, but disagree with it almost all the way.
- No, you don't have to like exercise for it to produce results. What you do, physically, is what produces results. If you care enough about the results, like the results enough, you will do the work. And if you don't care about the results, you don't have a problem to fix in the first place. This "having to develop motivation" thing is just an excuse, piling artificial obstacles in front of work that would be quite simple if you made an actual effort to do it.
- If there is something you genuinely want to achieve, then of course you start by researching how that thing is effectively done. With fitness, you don't have to do more than a few hours of reading to get the basics. Using those few hours to flail around with Wii Fits and treadmills gets you nowhere.
- The article completely ignores the most important part of the equation in trying to lose weight. At its core, being overweight is an imbalance of energy input and energy output. For various reasons, concentrating on increasing the energy output is almost guaranteed to fail, whereas you will definitely (barring rare medical conditions) lose weight when you drop the input to a suitable level, even if you don't exercise at all.
- The article positions low-intensity exercise as superior to intense exercise. Not true. For a person seeking overall fitness and wellness at minimum effort and time spent, doing either for the reason of burning calories up front is stupid (see last point; moderate calorie intake instead of futilely trying to "burn" them), but intensive exercise should be included in practically any general fitness program for other purposes.
- Granted, the suggested Wii Fit / game integration would effectively produce low-intensity exercise at no time cost. This could be a nice extra to a healthy lifestyle, but how many people would treat it as that? How many would instead consider it a sacrifice at the altar of the fitness gods, as filling some unknown "fitness quota" - just like so many people treat the entirety of a gym - and never take charge and decide how fit they want to be?
