With your arms fully extended in front of you, grab hold of a power or squat rack firmly with both hands. Take a wider than hip width stance with your toes slightly turned out. Keeping your core braced, bend at the knees and drop your hips down into a deep squat position. Your heels should remain in contact with the floor. This is your start position. Rotate your right hip in, bringing your knee all the way down towards the floor by your left foot. Rotate on the ball of your right foot to do so. Gently reverse the movement back to the start positon and repeat on the other side. Perform for the recommended number of reps (or time).
