It was cute the first few times you did this. Got some yukka yukka yukkas from the gym after they made sure everything was alright. But now, it's time to stop. No more missing the box once per box jump session. The inflamed, puffy, tender bruise that makes it hard to sit down comfortably is the last straw. No more. It stops today.
P.S. Also, if you could stop falling onto other things when you miss the box, that would be great, and really cut down on the bruises.
