What are your thoughts on this type of training? I'm a pretty fast kid, but I've never been clocked in the 40. Anyways, when the weather clears up here, I was wondering what your thoughts were on performing an exercise like this. Basically, I would be wearing a vest, attach a harness to the vest, then drag a sled with weights on top of the sled.
I'd basically be running 30-40 yards each set, and would do about 8-10 sets.
