1. Firstly, place a mat on the floor underneath your torso as you adopt an 'all-fours' position above it.
2. From here you will need to bend your elbows to a 90 degree angle and place your upper body weight onto your forearms. After you have done that, take a step backwards with your feet and place your remaining bodyweight through your toes.
3. At this point your body should be suspended (in a straight line) above the floor with just your forearms and toes as points of contact. This will be your starting position.
4. Keep your abdominal muscles tight throughout this exercise and keep your pelvis in line with the rest of your body to minimise risk of injury to your lower back (you can elevate your pelvis slightly to reduce lower back pain).
5. Next, exhale and lift one of your forearms off the floor whilst roating your torso. You should continue to rotate until your chest is perpendicular to the floor (facing the wall rather than the floor).
6. After a brief pause, inhale and return your torso back along the same path into the starting position.
7. You can either complete all repetitions on one side first or alternate as you go.
8. Repeat for the recommended amount of repetitions.
