Want to increase muscle mass, barbell exercises are the most important and basic exercises. U.S. forces, senior health coach to guide teachers to practice on the proposal to lift the bar into the first step for beginners, because the bar is relatively small range of motion exercises, it must be from a different angle (on the diagonal and oblique), using a different grip to stimulate the entire chest muscle. Relatively simple and safe practice is to flat barbell bench press, can effectively exercise the chest to increase the thickness. First lie flat on the bench press bench, feet on the ground naturally, and then adjust the body before and after the position of the eye in the barbell bench press rack just below. Grip slightly wider shoulder to shoulder, removed from the barbell bench press rack, slow decentralization of the bar until the upper arm parallel to the ground so far. Repeat this exercise thirty-four groups push for Europe is probably 12-15 times, depending on the specific individual physical condition.
