Hosaka-ryu Wellness Adductor and Pelvic Floor Muscle Training Color: Red Hosaka's training equipment Trains the adductor muscles, which are responsible for closing the legs. 〇 Exercise by squeezing it between your inner thighs! Targets the hard-to-train adductors and the often-loose pelvic floor muscles with easy-to-do exercises. Introducing the "Kyutto Zashake," an exercise machine produced by Naoki Hosaka, designed to train the adductors by simply squeezing it between your thighs and calves, addressing various concerns. 〇 Trains the adductor 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 holding 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 recess, allowing your pelvis to stand. The Biza Seat alone can be used daily as a cushion to maintain posture. It's an easy exercise to incorporate, as you simply sit and squeeze, making it easy for those who are not good at exercise to train.
