I agree. He is not as interested in the weight as much as building his stamina. I forget the name of the machines but it is the same product that alot of the NFL teams use. I know that Gold's Gym has them. Anyway, they are as close to free weights on a machine as you can get. They have a pretty good range of motion but are not set in stone like most machines. And they isolate each side like dumbbells. That looks like some of the equipment he is using in the video. They are very good and they actually work the stabilizing muscles also. If I remember the name of the equipment I will post it up. It may be Hammer Strength, I'll have to check.
