Gotta fuckin love hn, where you can't say the simplest thing without getting thrown into a well, actually.

I wasn't claiming to have run a damned study. Just making an observation. The thing is, people who don't enjoy exercising but start exercising anyway tend to find they enjoy it after a while. Saying people enjoy exercise is only slightly more controversial than saying "ice cream tastes good". There's a bit of activation energy required, but it's not a huge stretch to notice that something that is good for our bodies gives us pleasure.
