I am currently on a nice progression scheme for bench press where I do 3x5 on day 1 and 5x5 day 2 and then 3x5 with 5lbs more on day 3 and so on. This has been working extremely well.
But the same cannot be done for OHP. I can get in more reps. For example I did 3x5 on day 1, 5x5 day 2 and today I was able to manage 4x7.
OHP is a stubborn son of a bitch. I’m a little confused, though. Could you not get 3x5 with 5 more pounds today so you did 4x7 instead? Have you tried making the poundage jumps smaller (maybe 2.5 instead of 5)?
