By spring I’m guessing that you’re referring to pre-spring ball.
It’s a sequence from week to week, and block to block, and I modify the program every year.
At certain times the load is graduated in terms of volume and in others its graduated in terms of intensity.
There are different volume ranges depending on where we are in each training block and the intensity of the jump variants.
Short of illustrating what we did each week any volumes would only represent what did on a particular day.
I illustrate the general outline in my DVD entitled Bionergetic Sequencing in the Development of Sport Form.
In general, however, explosive throws will range from 10-50 total throws per session and the range is even bigger for jumps depending on whether the emphasis is more explosive or reactive.
