Hi, my name is Beth Hoover, and today I'm gonna show you the ultimate chest workout. Using an unstable surface such as the stability ball or a Bosu Dome, will help to challenge those stabilizing muscles of the shoulder joint and the chest that don't always get worked. It will also allow us to challenge the core muscles. I'm gonna show you four exercises today. For the first exercise we're gonna perform a chest press and a chest fly using a stability ball and free weights. Sitting on the ball, begin by ball walking forward, lifting your hips up, squeezing the glute, lifting the weights overhead, and performing a chest press, making sure to keep the abs tight, and exhale as you push the weights up. This is gonna work the chest muscles as well as the core and the glutes. And for the second exercise, we're gonna maintain the same position, but just perform a chest fly by taking the arms out, and then bringing them back overhead with palms facing in, squeezing the chest muscles and exhale as you pull the weights up. For the next exercise, we're gonna move to the wall with the stability ball. We're gonna perform a wall pushup with a stability ball placed against the wall, just press off using the chest muscles. To make this a little more challenging, you can slide the ball down to the floor and perform a pushup. The pushup is a great exercise to work those stabilizing muscles in the shoulder and chest. For the last exercise we're gonna take the ball to the floor to perform a decline pushup. Starting with your stomach on the ball, roll over the ball, walking with your hands all the way out as far as you can, lower three-quarters of the way down into a pushup, making sure to exhale as you press up, keeping the abs tight and the back straight. Repeat this exercise about 12 to 15 repetitions.
