Hi, I'm Chrisie Allemand, and I'm coming to you from BB3 Personal Training Center in Weston, Florida. Today, we're going to discuss what is a concentric portion of a push-up. There are three parts of the pushup, the eccentric, the isometric and the concentric. The eccentric portion of a push-up is when you lower your body down to the ground. With a tight core you actually have gravity helping you on this portion of the push-up and your muscles are lengthening during this phase. And the second part is the isometric. Isometric is simply just a hold. Muscles are tight, body is firing, that's the isometric. The third portion is the concentric and this is what most people think of when they think of a push-up. It's the strong part of the push-up, when you actually push yourself up toward the ceiling away from the floor. The concentric portion of a push-up is when the muscle shortens. So you push away from the floor, your triceps fire, they are shortening, your chest is also shortening on this motion. You are pushing your body up toward the ceiling, working against gravity. When you perform a push-up, when you lower down to the ground, you inhale. When you push away you exhale. I'm Chrisie Allemand. I hope this video has been very informative for you. Thanks for watching. Happy training.
