Two 40's

We used to do sprints on the back end of hops in college and I’ve seen Linford do the same. However after doing 360 yards of sprinting prior to the jumps, I didn’t feel as if it was necessary. Typically I progress from sprints to hops to MB to weights so I don’t really overlap any of the elements.

What have your results been with it (basically a really high depth jump into a sprint)?
