The reasons I exercise have changed over the years. Sure, I liked it when my belly was flatter, and my arms had a little more definition. Compliments are nice. But now, my #1 reason for putting on my sneakers, getting outside, or back on the bike or the mat is that I have plans for my next 30 years. If you can’t identify a why for something, that might just be something you don’t really need to do.
