MUSCLES ENGAGED Obliques Many people put a lot of focus on working their abs but forget their surrounding neighbors; the oblique muscles. Obliques serve as stabilizers, and are used in almost every physical activity. Exercising your obliques should be a very important part of your workout program. Forearms We don't often think about our forearms when we exercise. This is a little surprising as they are one of the most used muscles throughout our daily routines. Your forearms are involved in almost every movement especially when exercising. Every time you are required to grip anything with your hands, you’ll be using your forearms. Equipment Used Extention Rack A back extension rack is a piece of fitness equipment that helps to develop and strengthen the lower back and core. It can also help to develop secondary muscles, such as hamstrings and glutes. Exercise Instructions Step 1 Start on your side with your hands placed either across your chest or beside your head. Step 2 Keeping your knees bent and your lower body rigid, stretch out your side, then curl back up and contract your obliques at the top of the motion. Step 3 Lower your body back down, stretching out your side until you are back at the starting position and repeat action.
