Popular stability exercises

Lie on your back with your hips and knees bent 90 degrees and straight arms above your chest. Activate the lower and profounder part of your abdominal muscles, pull your navel inward, making a "flat abdomen". At the same time, lower one arm backward over your head and your opposite leg to the floor.

Stand on the floor with hands in TRX and elbows right under the shoulders. Lower the body down towards the floor and pull yourself back to the starting position with the elbows kept close to your body. The exercise is made more strenuous by changing the angle.

Attach a circular elastic band around your legs just above the knees. Lie supine with knees bent and apart in order to create tension in the band. Contract your buttocks and lift your hips off the ground while pressing your knees a bit out to the side to counter the pull of the resistance band. Mark the end position, return and repeat.

Start on one leg and with the centre of gravity right through your body. Distribute most of your weight to the back of your foot. The other leg should rest on a chair and be stable during the whole exercise. By focusing on your stomach and the lumbar region of your back, keep your trunk stable during execution. Perform a split squat by letting your upright body sink down towards floor. Stop the movement when you reach 90 degress flexion in the knee. Return to the start position by pushing down through your heel and extend your leg. Your trunk and hip should ascend upwards and forwards, fully enganging your hip and leg. Breathe in on your way down, hold your breath at the lowest part of the movement and breathe out on your way back up.
