Sit in a chair with good support for your back and make sure your feet are flat on the floor. Place belt around knees and tighten down until knees are gently touching. Squeeze and lift muscles of the pelvic floor (kegel exercise.) At the same time, try and separate knees putting pressure against belt, as seen in photo. Hold for 5 seconds, relax for 10 seconds and repeat 10 times.
Repeat sequence 3 more times, once a day.
