We had the guys Mon-Fri in the summer leading into the 2008 season and I was able to go three speed sessions per week M/W/F; however, it’s been M, T, Th, F since then so speed is M and Th.
Speed work over this summer was power during Blocks 1 and 2 and capacity during Block 3.
Block 1 hill sprints (adapted from CF GPP on Monday only)
Block 2 sled sprints on the field
Block 3 capacity sprint series (no sled) on field for veterans and capacity with sled on field for new freshmen
I must note that none of my skill players are required to do the assigned workload for the day. I only require that they communicate to me what they are ready for and give me 100% on whatever that is; be it in actual intensity of best or via focus/mechanical execution of a reduced intensity workload (ergo power speed instead of sprints).
As a consequence, over the 12 weeks of summer I had one single player (scout team) sustain a minor hamstring pull because he did not communicate to me that he was tight and pushed himself too far. As I stated it was a minor pull though and he was back running tempo in less than a week.
