Wen Shu demonstrates a simple exercise to help with lower back, lumbar, knee and ankle pain, as well as urinary incontinence and prostate issues. It may even help with weight loss in the lower belly.

You will need a chair for this exercise.

Lay on the ground in front of the chair, placing your calves flat on the seat.

Slide down as far as possible, until the seat touches the back of your knees.

Grab and hold on to the front legs of the chair for support, and to prevent the chair from sliding away.

Bring your buttocks up until your shoulders, bellybutton and knees form a straight line and your calves are off the chair with your weight resting on your heels.

Hold this position for a few seconds, until you start to feel sore. You will feel your buttocks and back of your thighs working.

Release back down to the floor and take a few breaths.

If you are able to, repeat the exercise a few more times.

For best results, perform this exercise several times a day, up to 20 minutes total.
