New, Unused Hosaka-ryu Wellness Inner Thigh Training Kyutto-za Shake, Brown [Product Information] 〇 Exercise by squeezing it on your inner thighs! This product allows you to exercise your hard-to-train inner thigh muscles and your often-loose pelvic floor muscles while doing other things. Naoki Hosaka, focusing on various concerns, produced this exercise machine "Kyutto-za Shake" that trains the inner thigh muscles simply by squeezing it between your thighs and calves. 〇 Training the inner thigh muscles, which are responsible for closing the legs Sit on the Biza Seat (seat) in a position that allows your pelvis to stand, and select the vibration mode while squeezing the machine (main unit) between your thighs and calves. By exercising to close your legs, you can target not only the inner thigh muscles (adductors) but also the pelvic floor muscles, abdominal muscles, and gluteus maximus, which are linked to the adductors. 〇 The Biza Seat supports correct posture The Biza Seat has a shape that fits your buttocks in the seat's indentation and allows your pelvis to stand. The Biza Seat alone can be used daily as a cushion to maintain posture. It's an exercise you can do just by sitting and squeezing, so it's easy to incorporate even if you're not good at exercise, and you can easily train.
