I do the Obstacle course run type work outs.
Flip tractor tires, pull ups, muscle ups, wall climbs, snatch, cleans, squats, triceps extensions, curls...weights with heavy(for me) chains.
Lots of treadmill and martial training make up my cardio work.
My intention is to build explosive strength and stamina.
Do to the nature of the cardio work, I do not gain much in the way of size.
I am not a heavy weight so my results might be different than another person that does what I do.
