Looks like 5 weeks of single arm work didn’t help my overhead press at all… in fact, it was counterproductive, just as I expected I really need to figure out what the **** is going on with my arms and why they absolutely refuse to get stronger.
I'm not going to bother repeating this again, so take it or leave it...
The past 5 weeks or so you've been working on upper body, you've been lifting in the 1-6 rep range. Only once did you go as high as 10 reps according to your log.
You aren't a beginner anymore kerpal, you have some advanced level lifts, meanwhile your bench is stuck between novice and intermediate.
Stop following other people's programs(which are generally built for beginners) and start writing your own based on what works for your body.
You've been addicted to this low rep work for as long as you've been lifting, and while that's apparently worked great for your squat and deadlift, it's been trash for your OHP and bench press.
Start lifting in the 8-15 rep range for 2-3 sets and get outside of your comfort zone(1-6 reps).
1) Test your max on flat bench and overhead press.
2) Take 60% of it and work up to 2 sets of 10-15 reps.
3) Increase load at 2.5-5% a week, still 2 sets of 10-15.
4) Increase load until you hit 95% of your max for 10-15.
5) Then test your max again for both lifts.
* Deload every 4-6 weeks.
** The week after deload, start back 5% LOWER than the week prior to your deload. 3 steps forward 1 step backward.
Example: week 0 MAX TEST, week 1 60%, week 2 65%, week 3 70%, week 4 75%, week 5 deload 40%, week 6 70%, week 7 75%, week 8 80%, week 9 85%, week 10 deload 40%, week 11 80%, week 12 85%, week 13 90%, week 14 95%, week 15 MAX TEST.
I'd be VERY surprised if it wasn't higher, and if you weren't much stronger.
If you aren't interested in that, I'd pick up a copy of Wendlers 531 program and try it out for a few months.
This low rep 3x5, 5x5, whatever, it. does. not. work. for. your. presses!:cuss:
Good luck man, your progress over the years on your squat and deadlift are inspiring, but your stubborn refusal to learn from your own experience on upper body movements is irritating.
