I’m 15. I do Incline bench presses, Flat Bench presses, Tricep Pushdowns, Wide grip pulldowns everytime i go the gym. I do about 50 reps for each exercise. The result is, my arms get bigger but my chests just get a lil bigger. So, how to have a bigger chest? What exercises can makes it happen?
50 reps per exercise? thats the problem..
8-10 reps is for building size
12-14 reps is for power and endurance
Your doing the right exercises.. just work on the the reps.
The last 3 pumps on the 8-10 set should be very difficult. If not.. increase the weight. Try to do 3 sets of 8 for example for size. Everyone has their own way of doing things.. but this is a good overall consensus.
