We’re currently using this Mini Study to test how to program cluster sets.
I came into it straight off our Rock Climbing Pre-Season Training Plan, which includes little lower body strength work. My Week 1 back squat 1RM was 325. After three cluster squat sessions, my Week 2 back squat 1RM moved to 345.
That doesn’t mean cluster sets are the reason. More likely, it shows what we’ve seen before — strength comes back fast.
The bigger question is programming. Right now, the progression starts with a 1RM, then uses two sessions at 85% and one at 90% before re-assessing. We considered pushing the progression to 95%, but that may be too aggressive if athletes can’t make the reps. Could they complete the work at 95%? Could we push to 100%? We don’t know yet. That’s for another study which will include more exercises than just the Back Squat.
