I have an intense bodyweight routine going and I want to keep it up. Somehow, I want to get Bitcoin into this to 1) motivate me and 2) for the amusement of it. You know, like take bets on my gains or if I am going to flake out altogether. Right now I am of an idle bodyweight at 6', 155 pounds. Mostly fat, me thinks. I can provide pics of my "before" body, etc.

So, give me some ideas. ...or is this not viable?

That would be an expensive weight. Anyways, my workout consists of all bodyweight exercises. Handstand pushups, squats, bridges, etc. I'll go to weights if I can no longer get any gains from these exercises, which won't be for awhile.

Go work on a construction site and ask to be paid in Bitcoin.
