SUPER COMMON problem. One way you may find relief is to take a hard look at what you are doing for front delts. Lots of people's benches stall because the front delt gets pounded with all the chest, tricep, and front delt work. I put together many routines witout any, or very little front delt work and this can really make a difference as to if your bench stalls or not. Of course without seeing your bench (chest/shoulders/tricep) routine, and overall routine structure it's hard to say. But reviewing what you are doing for delt work is a good place to start. Also, where is your sticking point? High or low?
