Since I've started working out I've noticed increases in everything except my bench. What gives? I vary my workouts, but I seem to be stuck right where I'm at now. I really want to build my chest some, but it just doesn't seem to be happening. I do a variety of stuff including days of 4 sets of 12 (usually 2 each on decline/flat, flat/incline, or decline/incline. Also days where I do 10, 8, 6, 4, 2 while increasing the weight. I do a total body workout M/W/F. I'm wondering if maybe doing chest only on Tues/Thurs/Sat (not doing it on the other days though) would help.
