Why do some people only like to exercise alone, while others only like to exercise with a group class?
I asked that question to the Trainer at my club. He said he didn’t know?
I don’t either. But I always exercise alone and my wife ONLY exercises with a group.
So I Googled it but didn’t get much. Just this from About.com — exercise which is far from statistically valid. Even so, it surprises me: I thought most would opt for the group.
