This is Lisa Thiel, and we're going to talk about assisted pull-ups versus assisted chin-ups. Both are great movements focusing on your back, biceps, and upper body strength. Sometimes, we can't do them without help, and today I'm going to go over the difference between a pull-up and a chin-up, and how you can get some assistance until you get that foundation of strength. Pull-ups and chin-ups are a great strength movement. Sometimes, you need a little assistance before you can get there on your own. One of the easiest ways to assist yourself while learning to do or gaining the strength to get a pull-up or a chin-up is to use a box. We call it a jumping pull-up or a jumping chin-up. Simply step onto the box. You want to make sure that you can extend your arms completely. And then, when you jump, you're pulling and you're jumping at the same time to activate your upper body. That's an assisted pull-up. For an assisted chin-up, simply turn the grip of your hands around so palms are facing down. Same thing -- the bar is directly over my hips and my shoulders, and I'm going to jump and pull at the same time. One thing you want to be careful of is holding yourself at the top. -- you don't want to do that; you're going to end up getting really sore arms. Make sure that you allow yourself to drop every single time, and trust that you're going to catch yourself on the box.
