【Product Name】 Kenbi Stretch Device Yawara Bijin Kaikaku Better 【Included Items】 Body only 【Product Features】 This is the "Yawara Bijin Kaikaku Better" stretch device, developed by Chika Amasaki, a Kenbi stretch trainer, based on her own experience. By sitting on it, you are naturally guided to a beautiful posture, and by swaying gently while using your own weight, you can stretch the muscles around your hip joints and perform leg-split stretches. Stretching the muscles around the pelvis and hip joints supports posture, helps create beautiful legs, and supports the lower back and knee joints. 【Yawara Bijin Kaikaku Better】 ■ Sit and achieve beautiful posture: The backrest supports the sacrum and is shaped to lift the pelvis, which tends to tilt backward. Sitting in the recess of the seat naturally leads to a beautiful posture. ■ Sway and easily perform leg-split stretches: The rounded bottom allows for rotational movement using your own weight, and the back support allows you to easily sway forward, backward, left, and right while keeping your pelvis upright. Inside the urethane cushion at the bottom of this product, a special core material called the "special leg-split plate" is used, which is a spherical plate that supports leg-split stretches using the principle of leverage. Exercises that apply external force can easily cause tension and stress on the body, and when trying to perform leg-split stretches on your own, your back may round, but by using your own weight, we believe that it can reduce the burden on the body and provide a relaxing effect. 【Materials/Ingredients】 ・Side fabric: Polyester, polyurethane ・Filling: Polyurethane ・Core material: Polypropylene 【Size】 ・Approximately W32 x D45 x H35 cm ＜Suitable Size＞ ・Up to 100cm hip circumference 【Condition】 There is a slight feeling of use on the fabric, but there is no noticeable damage or feeling of use, and I think it is in relatively good condition. It is a product that can still be used for a long time. For shipping, we will wrap it in cushioning material to prevent damage and then wrap it with wrapping film. Thank you.
