Stand up, and try to keep the balls inside your vagina by squeezing the pelvic-floor muscles to resist gravity. If you relax, the balls will fall out. As you do this exercise regularly, you will be able to hold the balls inside for longer periods. Do this exercise at least three times a day. To add difficulty, walk around with the Kegel balls inserted.
With Kegel balls inserted, open your legs at least hip-width apart, and start squatting. Keep your chest up, and push your buttocks far back. As you sink into a deeper squat, the intra-abdominal pressure will make it difficult to keep the balls in–you have to squeeze hard, or they will fall out.
Just like in the standing and squatting exercises, insert the Kegel balls into your vagina, and keep them inside during your daily activities: cleaning, shopping, walking the dogs, showering or working. This is an advanced stage of Kegel ball exercises, and you should be strong enough to keep the balls inside for prolonged periods.
Remove the Kegel balls by inserting an index finger in the vagina behind the ball, one at a time, then relax the pelvic-floor muscles, and pull each ball out. Wash them in warm water with mild soap, and rinse well to avoid irritation of vaginal tissue. If you have any gynecological problems, consult your doctor before using Kegel balls.
