Exercising takes a really long time. If I wanted to be physically active, I need to allocate a big chunk of my day towards exercising, which means I need to give up something else --- something I actually enjoy.
One thing that physically active people tend not to realise is that not everybody finds exercise enjoyable.
I am not particularly unfit; I do various physically active things; but for me, regular exercise is horrible. I find it an utterly miserable experience; uncomfortable in every possible way, and worst of all, incredibly boring. And it never gets better. A while ago I made myself train up and enter a 10km race, and completed in a reasonable time. As I progressed, the only thing that changed was that I was capable of prolonging the discomfort for longer. That's a negative feedback loop! I was so glad when I actually completed the race and could finally stop.
I am so, so jealous of people who actually enjoy doing this crap.
So if there's a side-effect free way of getting the health benefits of exercise without having to put up with an hour a day of tedium and lactic acid reaction, that would be amazing.
