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! Targets hard-to-train adductors and loose pelvic floor muscles with while-you-do-it exercises. Introducing the "Kyutto Zashake," an exercise machine produced by Naoki Hosaka, focusing on various concerns, that trains the adductors simply by squeezing it between your thighs and calves. 〇 Trains the adductor muscles, which are responsible for closing the legs. Sit on the Biza Seat (seat) in a position where your pelvis stands up, and select the vibration mode by squeezing the machine (main body) between your thighs and calves. By exercising to apply force in the direction of closing your legs, you can target not only the inner thigh muscles (adductors), but also the pelvic floor muscles, abdominal muscles (abs), and buttocks (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 and raises your pelvis. The Biza 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.
