What exercises would you recommend to be done in under 15 minutes for bulky arms. I have tried some weight exercises in the past, but they failed to show results because of lack of follow through.
You probably won't get bulky arms in only 15 minutes of lifting, I would recommend at least 25-45 minutes twice a week if you want bulky arms.
Some good exercises for mass are: 1) 4 sets of 6-8 heavy barbell curls 2) 3 sets of 10-12 hammer dumbbell curls 3) 3 sets of 10-12 seated alternating dumbbell curls
It's import to "squeeze" the muscle at the top of the movement, and come back down slowly. Most of your growing and muscle fiber tearing happens on the negative of the rep.
