I cannot recommend Charlie’s materials enough for those in your situation who require the deepest possible understanding of sprint training.
Assuming a general organism strength approach will widen your view considerably regarding the many variations of weight training that may effectively carry one through SPP and the competition calendar.
Establish high enough general strength levels pre-season in a concurrent fashion, on the lifts of your choice, then arrange those lifts serially throughout the competition calendar; thereby only requiring one primary weight training exercise to serve as the primary general organism strength stimulus with the rest being performed in an auxiliary/supportive fashion until it’s their turn to assume the primary role in a subsequent block.
I won’t go much further on this topic here because Charlie already did that for us.
