Hi, I'm Shaun Zetlin, and I'm here to show you how to create dynamic tension without lifting weights made popular by Charles Atlas in 1920. Today we're going to do a front lateral to work the shoulders, the triceps, the biceps and the forearms. So today I've chosen to do the front lateral and I'm going to create some light tension against Uran. You want to make sure when you are doing this with your partner that you do not create too much tension because you don't want to injure them. So to start, she's going to have her feet, knees and legs together to work her core. I'm going to face her. She's going to have the dumbbells down, that's called the pronated position. She's going to bring the dumbbells to shoulder level and when she gets there, I'm going to push against her. I'm going to use some tension but not too much because again we don't want to injure her, all the way down as she resists me, and then back up. You don't want to come higher than shoulder level during this exercise. It's going to work the shoulders, triceps, biceps and forearm and if you come higher than shoulder level you will get the upper trapezius involved. She's going to show you what that looks like now. That would be the incorrect way. She's working her trapezius muscles and that's not right. So again, keep the shoulders back, trapezius muscles down. We'll try it one more time and we're pushing up against her in a gentle fashion to create dynamic tension.
