Hosaka-ryu Wellness Adductor and Pelvic Floor Muscle Training Hosaka's training equipment Trains the adductor muscles, which are responsible for closing the legs. 〇 Exercise by squeezing it between your inner thighs! Addresses hard-to-train adductors and loose pelvic floor muscles with simultaneous exercise. Focusing on various concerns, Naoki Hosaka produced the "Kyutto Zashake" exercise machine, which trains the adductors simply by squeezing it between the thighs and calves. 〇 Trains the adductor muscles, which are responsible for closing the legs. Sit on the Mizasa Seat (seat) in a position that allows your pelvis to stand, and select the vibration mode by 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 Mizasa Seat supports correct posture. The Mizasa Seat has a shape that fits your buttocks in the seat's indentation and allows your pelvis to stand. The Mizasa Seat alone can be used daily as a cushion to maintain posture. It's an exercise that you just sit and squeeze, so it's easy to incorporate even if you're not good at exercise, and you can easily train.
