['I exercise often but as a powerlifter I do very little cardio and never really had much interest in it. A friend of mine introduced me to marathon running and wow, I like it much more than I anticipated!']
I'm glad you've found a change of pace.
I'm a powerlifter so I focus most of my time exercising lifting weights. A friend of mine just recently introduced me into marathon running and boy, I didn't expect to like it as much as I do.
