Believe it or not, as an athlete I hated 95% of the medicine ball training we did. To me it seemed somehow stupid just throwing a ball 200 times around just to do it. The other 5% have been fun and I loved it. This 5% was the most challenging stuff. I loved it because it had concrete purpose. It might have been as simple heaving the ball up to the ceiling, but that wasn't easy so it presented a challenge and a purpose.
