I stick with the 30 pound dumbells and do 3 sets 11 reps on all my excercises should I go to 35 pound bells now or? and how many reps should I do 4-8 for big muscle gain?
If you do a rep range of 8-12 then Choose a weight that you can just do 8 reps on and continue that until you are able to do 12 reps might be a couple of weeks. Then increase the weight so you can only do 8 reps again and carryon this cycle.
