POB doing it Westside style.....How do I increase my bench? That is a loaded question. It depends where your weak point it. Is it off the chest? Is it the middle? Is it lockout? Are you tucking your elbows? Are you using lats to lower the bar? Are you triceps strong? You must determine where you fail and do things to help the weak point:
off the chest=speed work, chain and band work, pin presses, floor presses
mid chest = 2 and 3 board presses
lockout= reverse bands, heavy tricep work ( extensions, close grips...)
