My small skill guys handle 2000yds of tempo very routinely 2x/week whether it’s 2x10x100yd with pushups or abs + 30-45sec btwn reps or 2x5x200yd with 2min btwn reps.
In both cases they’ll walk around the field 1 or 2 times between sets
As far as the 100s go, we’ll begin post season and post spring ball with:
wk-1 2x6
wk-2 2x8
wk-3 onward 2x10
This is not to state that we must perform this volume to be successful; however, this has historically proven to be very manageable as well as highly beneficial and hasn’t shown any sign of taking away from subsequent speed sessions.
