Entertaining for me is doing several things that I have to think about at one time. I read while I watch the tv shows I like. While I'm browsing this forum and writing this, I have a book open. Exercise is entirely too boring for me.
I've managed to enjoy swimming I can count my strokes between breaths, concentrate on my form, and think about stuff. I know an exercise plan can't just be one activity though. Has anyone else found something brain challenging to not be so bored?
