Isometric Single Leg Deadlift

The concentric portion of this exercise. The athletes were doing heavy triples followed by box jumps. The isometric was using the sets/reps of 3 sets 7 sec holds. 60 seconds rest. They were often paired then with a high velocity exercise in the form of some type of jump following completion of the isometric. The theory behind the iso is that it really builds and recruits the motor units. These are very taxing.
