The Power Sandals offer effective legs, bums and tums training now even in the water. The AquaTwin provides enough buoyancy, so that you can move freely and unconnected in the water without any additional buoyancy aids. In particular they provide effective training for the lower extremities: whether in shallow or deep water, during aqua jogging or aquatic fitness training: the buoyancy and additional resistance on the legs lets all the muscle groups in the legs, buttocks and tummy come into play! The AquaTwin also provides optimum training for the upper body: like with AquaDiscSZ there are two openings hidden in the “twin” which can be “grasped” with thumb and finger. In this way arm, shoulder, chest and back muscles can also get a good work out. الحالة جديد
