Heavy hip extension for the run and the takeoff
Back squat or trap-bar deadlift at 80 to 90 percent of one-rep max, 3 to 5 reps, 3 to 5 sets, twice a week in the off-season. The approach is a sprint and the takeoff is a single-leg jump into a plant, so the same qualities that build a 100m build both. Sprinters run the same block, laid out in weight training for sprinters.
