I would like to inject that proper progression is absolutely necessary for power/explosive training. And recovery is probably the most important aspect of such training.
And personally I like to use a variety of resistance systems to apply the load for this type of training. Resistance that is designed to increase load and then decrease load smoothly through the execution of the movement. There are a lot of ways to do this. And that is something that I teach CECs on that can be introductory, 4 to 8 hours. Or very deep, 40 to 60 hours.
