Start in knee supported plank position - elbows and shoulders align - forearms parallel - keep hips square to the floor - extend one leg - turn the foot so that the inner edge of the skate is at a 45 degree angle to the floor and then tilt your ankle towards your outside edge, this will position the wheels correctly and you will not scrape the boot along the floor - Keeping leg extended pull upwards and out to the side - try not to rotate at the waist, keep shoulders and hips square to the floor - flexibility will determine how deep into crescent moon you are able to roll your leg - do not force the position, roll the leg as far as feels comfortable - reverse action returning to start - continue with the action - alternate legs and repeat.
