Dan-
What would you call the type of work that his coach is prescribing?Meteoric-
You could definitely benefit from more strength work. I don’t necessarily think the prescribed workout is all that bad but I probably wouldn’t do it for 15 reps as by that point the quality will really degrade. 10 reps (and more likely 8) is usually my limit on activities like that.
Mike:
a specific weightlifting endurance type of program. The intensity of the lift may make it worthwhile, but I think a better power endurance routine for the amount of time used would be one that is skipping, bounding, or running for 12-20s reps. For the session to be really working on power then either rate or weight lifted need to be controlled. I personally don’t really think power-endurance is effectively trained with weights beyond 5 or 6 reps for most types of athletes. If you are going to work power endurance beyond 8 reps then you have to start doing body weight type activities or medicine balls. For power endurance work to be effective I think the rate has to be near consistent throughout the duration of a set.
