Yeah, implementing these kind of things is awesome and useful at the same time.

At another opportunity, I actually experimented with doing something similiar while playing online games. At the time, I was playing Smite and was wanting to give me some extra incentive to become a better player while also doing something good for me.

The result was that I ended up doing squats and push-ups as "penalty" every time I died ingame. I definitely felt the bad games afterwards, let me tell you.
