Patient discussion about biceps

Q. What is a fast and effective way to get bigger biceps and triceps? I am one of the regular goers to gym for the past 6 months and I am very fond of disposing my biceps and triceps. What is a fast and effective way to get bigger biceps and triceps?

A. I would not do any curls at all. Instead focus on multi joint, compound movements. Try back workouts, pull ups, chin ups, etc.

These will work your biceps. Make sure to go as heavy as possible without hurting yourself, and consume protein. The rest and drink alot of water. Sleep adequately.
