I've been using this beuty and it really works . here a cool review also

Convict conditioning lmao

I'm sure it one hellva of a workout with the bare essentials, but its just funny seeing a training vid and book on this. Now I've seen it all.

Its dragondoor. Theyve been around a while. I got my kettlebell from them many years ago. Now i can just go to the local sporting goods store and get one.

Ive been meaning to pick that book up.

Pretty similar to Convict, but harder, lower reps.
More size increases.
