Funny story after playing football in college I needed something to keep in shape and get that competitive high, so I decided to train for TinMan's. Would run 7 miles, lift, go for 30 mil. bike rides, swim laps for a mile, kayak for 4 hrs. Was in the best shape of my life, right. Wrong, girl I met said you should try yoga. OK I figured this is girly stuff no problem. Go to class with her, it's some type of power yoga. I was sore in places I didn't even know had muscles for a week. Needless to say I never went back to a yoga class again in my life after that experience.:)
