Chest growth problems is probably the most common training related problem or question people post about on MESO by far.
Unfortunately, we can't diagnose problems or give proper advices without the following information: how frequently do you train chest, what movements do you do, how much volume do you do per movement, what intensity / percentage of 1rm do you use for each movement, and what is your progression model / when do you add weight? Answer these and we can advise better.
Whenever someone posts up a routine or a day from their routine they are having problems with, my eyes immediately look for a few things:
1st is frequency: most of the time it's too damn low. Y'all fuckers is on gear, get some frequency in there.
Next is weekly volume: is it too low? This is an extremely important variable but intensity has to be there as well.
Next is intensity: is it too low?
Next is exercise selection: anyone who is having problems with any muscle group should NOT be doing 10 different movements, they need to cut that shit down and invest that volume across a smaller selection of movements. Increased specificity in exercise selection is one of the BEST ways to break through a plateau.
