5 sets x 10 reps
Nutrition-wise Im ok just can't seem to get enough protein in a day
thanks
I assume that you're infering that the heaviest DBs that you have in your hands are 50's? If so, it's going to be very hard seeing very noticable improvements to your chest doing straight sets of 10 at 50 pounds. Doing the same thing over and over again is not going to force your body to adapt and grow.
If you're limited in terms of weight, you have to progress on another variable. Either add reps, decrease rest time, slow the tempo down, or do isometric pauses at the bottom of your movement. Do supersets with a bodyweight movement, a mono-articular movement or with bands (doing flies).
After gradually progressing on those variables, either hope the gyms reopen soon, or buy heavier DBs, rince, and repeat.
All bodyparts answer to being put under increasing tension. Your muscles don't know what DBs you have in your hand. They answer to tension. It's a long process. And also remember just annihilating a bodypart is not always the way to make it grow quicker. Doing 5 sets of 10 on 5 separate exercises for a single bodypart in a single workout (if I understood your regimen correctly) either means:
A) The tension put on your muscles in a single set is insufficient
B) You're taking too much rest
C) You're not using proper form/feeling the muscles enough
D) You have some pretty awesome recovery abilities and workload endurance
Try to see which one it is and adapt appropriately.
