RE: Dumbell Chest Workout Hindered By Arms
If you are working your chest on Monday, and shoulders on Tuesday and Wednesday then on the assumption that you are doing more than just raises for delts, your arms are being worked 3 days on the trot. No wonder they are struggling to keep up. And then you are working them again on Thursday?? It's way too much, and you don't need all of them chest exercises. Flyes aren't necessary, and neither are decline presses. Also, if you are trying to balance out your chest development then I don't see how you can do that if you are doing declines which presumably are being done to target the lower chest?
Bombarding your chest with tons of exercises and lots of volume will not help to bring it along, what will help is good solid form and weight progression along with REST!
