Hi, I am 19 years old and weigh 100 pounds, almost impossible to gain weight...
so I recently started trying to build muscle in march and bought dumbbells, right now I am lifting 15 lbs about 30 reps, wait 3 min, 25 reps, wait 3 min, 20 reps. I usually do this for like 30 min at the most in a day. I am wondering if this will ever give me results because so far I don't see any. Is there a wrong way to lift? Usually I keep top of my arm straight down and lift only forearm up all the way.
Oh, when I try to switch to 20 pound dumbbells, it is too much for my wrists. Even though I keep them stiff, they still sprain. My arms are strong enough but wrists are way too skinny.
