You typically seem to give decent advice IIRC, but for some reason in this thread you showed pretty limited thinking. Maybe 10x3 would wipe you out, but it doesn’t sound all that bad to me, and it was a little dogmatic for you to say “should be around 85%” as though that’s chiseled into a stone tablet somewhere. Perhaps if the goal is performing 10x3 with short rest, as part of a fat loss or conditioning protocol, one might change the load? Why assume that it must be 85 percent?
Anyways, let’s ask the author of the program in question:
(note that the program mentions performing the 10x3 with one minute rest between sets)
“Any rest period between 60-120 seconds will work, but each lifter will require a different rest period based on previous training and other neuromuscular issues.”
Note that in the “fat loss” 10x3 article, he shortens the rest period to 45 seconds.
Conclusion: rest periods and loading can be varied and should be tailored to the lifter’s goals and what they’re able to handle at a given level of conditioning. Hm. Who woulda thunk?
