Chinups vs. Pullups for Bigger Arms (THE VERDICT!)

Should you do chinups or pullups if you want to build bigger arms. This video is finally here to answer the question for you and help you to build big arms fast. As with any situation where you pit two popular exercises head to head, you are going to get people who defend each one. I’m going to do the same, and give you the best parts about both the pullup and chinup and how they work different parts of the arm so that you can decide which arm exercise you want to focus on. First, we must start as we always do with a little bit of anatomy. The upper arm consists of the biceps and triceps muscles. As we know, the job of the biceps is do supinate the forearm and flex the elbow. It also has the ability to flex the shoulder since it has a biceps long head attachment that crosses the joint. The triceps of course are designed to extend the elbow and bring the arm back into extension behind the body.
