Regarding the 1 rep max calculator, can you clarify something?
I'm trying to get to 315lb 1rep max. When I type in 315 for 1 rep, it says the 5 rep max is 271lbs. When I type in 271lbs for 5 reps, it says 1 rep max is 305lbs.
I know 1 rep max calculator's are not accurate for everyone, but still I'm just trying to get an estimate.
