just looking for some opinions, will higher rep sets (at a reasonably heavy weight) make your muscles harder as opposed to low rep sets? For instance, if I did 6 db curls with a 55 lb dumbbell, but I can do 10 reps with a 50lb db, will the 10 rep sets, if continued training in that manner lead to visably harder muscles (appearance wise and touch wise) ? Or is it psychological? Sometimes the day after a nice heavy higher rep workout, my muscles still feel fuller and almost more defined than if i did a low rep, high weight workout. Is it all in my head, or my eyes for that matter or is there something to higher rep sets with a heavy weight?
I am not talking about a huge weight difference, just taking a heavy weight to 8-10 reps as opposed to a heavier weight taken to 4-6 reps.
did that make any sense?
