The hurdle progression I use is something I took off Stu McMillan’s work. As I progress through a training block I gradually increase the distance between hurdles while concurrently raising the height of the hurdles. Eventually trying to get 39-42 inches with 12 feet of spacing.
Another variant I have used is doing hurdle hops over 30 yards to work on elastic endurance.
With the MB throws I most often utilize the “Bomb” sequence from Pfaff, although I sometimes substitute the OHB for a vertical toss to keep from activating the spinal erectors. I also will do this series using a 2-3 second pause to simulate exploding out of a stance.
