Insync Physiotherapy 604-566-9716 http://www.insyncphysio.com 4088 Cambie St. #102 Vancouver, BC V5Z 2X8 Maintain a flat lower back with your feet in the air and your knees toward your chest while you keep your inner core muscles engaged below your belly button. Start by slowly lowering one bent knee down to allow the foot to reach the ground, and then return it to the start position above ninety degrees. Ensure that your lower back remains flat and the opposite knee and leg do not move. Repeat this movement for 10 repetitions, doing 3 sets on both sides. This exercise is great if you have hip impingement pain with muscle imbalances and weakness coming from your hip flexors. If you have any pain during the exercise or are unsure about what you are doing, consult your local Physiotherapist before continuing.
