re: PuttaDaForkDown

So my bench has been stuck at 135x5 for the last 6 months. Hasn't gone up. I've tried many times to go up 10 or even 5 pounds and hit failure before I get to 5th rep. After researching and again filming myself to see my form; I corrected my hand position (was using too much wrist, actually causing my wrists to hurt) and spreading my elbows out rather than keeping them in. Still, corrected form and all, I've been stuck at 135. So I did more research. I fail at the top of the lift, before lockout.. so I've determined that my triceps are holding me back, and sure enough once I corrected my form, my triceps are on fire and pretty much dead after a 5x5 bench at 135. So, I've decided to do some isolation on triceps twice a week to build them up. Today was the first day I did some isolation. What I found is that my left tricep is amazingly weaker than my right. The difference is substantial. My left tricep hit failure 3-4 reps MINIMUM before my right when I used dumbbells. That is some serious muscular imbalance. Anyone have any tips on how to correct this?
