Core Crossfit Black New L～LL Waist: 69-85cm The key is the special uneven processing of the material. With exquisite pressure and the uneven stimulation of the fabric, it strongly approaches the abdominal muscles. Especially, it powerfully works on the rectus abdominis, which is necessary for tightening the waist, the external oblique muscles that create the curves, and the transverse abdominal muscles and internal oblique muscles, which are the key to a flat stomach, from three directions! These muscles are deep inside and are difficult to move just by doing regular abdominal exercises. This is an excellent product that efficiently works them. The double V-shape in the front and the X-shape on the sides, made of power net, firmly tighten the pelvis! It corrects pelvic misalignment and prevents the abdomen from sagging! Also, the two bones in the back support correct posture. It straightens the back and encourages natural drawing-in (diaphragmatic breathing) by being conscious of the abdomen!
