I trained OHP for last 2 years more or less in 3x5, 3x3 range or ramping singles.
I have 85kg. I can do barbell military press 52kg for 1 rep (47kgx3, 45kgx5) throughout last months.
Now I wanted to do two months of some high rep volume workout, like 5x20 reps.
I calculated 20RM should be around 60% = 31kg.
It turned out that with 29kg (56%) I could hardly do 15 reps first set, and hardly 12 reps on next four sets.
Is there really such discrepancy with 20RM calculated percentages or my muscles aren’t used to high reps? Low glycogen stores?? I am not really used to pump it seems, especially in triceps.
Same is with dumbbells.
Any thoughts? Opinions? Is this normal?
PS I dont take any creatine…
