Well i have been working out my arms and my chest a lot lately (along with my other body parts) and i dont see alot of improvement. In 4 months i went up by 10 in arms and 5 in chest meanwhile my friend upped by 20 on each.
What should i do to increase to my arm and chest size, and also building mass and power?
Should i use low weights and alot of reps to build the size and definition, and than use heavier weights to build mass?
Like for example, i would do 3x15 reps for arms with a 20pound weight and than do 3x8 with a 30 pound weight? Would that build the size/definition and also mass?
If not, what should i do?
And also, are there any tips into gaining improvements faster, like should i eat better, should i eat before/after gym, etc.. and how many different exercises should i do for each body part?
Thank you for your time and help
