SVAKOM Kegel Balls are an expertly designed set of three different exercise balls to perform kegel ball exercises. Each Kegel ball is equipped with a silicone string to easily take out the ball after use. The entire kegel ball is made of silicone which is 100% waterproof. According to the kegel exercise theory, we designed these kegel exercise courses especially to help those who have a loose vagina before or after giving birth. The set of kegel balls have three gradual increased weights for different exercise needs. Effective kegel exercise helps to strengthen a woman's PC muscle (pubococcygeus muscle), improving health while bringing sexual benefits and satisfaction. For daily exercise or postpartum recovery, SVAKOM kegel balls are the perfect choice for your PC muscle strengthening needs.
