Hi, I'm Scott White here in Scottsdale, Arizona. I'm going to talk to you about pronated chin-ups and your hand muscles. So a pronated chin-up obviously is a pull-up. When you do a chin-up your hands are supinated and you grab the bar. When you do a pull-up you rotate your hands this way. But the hand muscles that are involved are your flexor muscles in your forearms that go what obviously help strengthen your grip and holding on. The stronger your grip is the more pull-ups you can squeak out. It is a direct correlation to being able to do a pull-up. If you have a very weak grip you can't hold your body up there, you're definitely not going to be doing many pull-ups. The importance of strengthening up your hand muscles can carry over to everyday activity, right. So anytime you pick up a weight, or pick up your groceries, or cat food, the stronger your grip is the easier that becomes. So doing chin-ups will obviously make your grip stronger as well as other exercises. So a chin-up you're grabbing the bar, you're squeezing the bar as you pull up. Remember chin-ups are a great way to strengthen up your hand strength by holding tight and gripping that muscle. You can add weight to your chin-ups which will make you have a stronger grip. There's a lot of carry over to other activities you do in life.
