Did you know that posture and the balance around the pelvis are actually important? "Core Slim" aligns the pelvis just by sitting, and by swaying back and forth, you can easily expect to train your abdominal muscles. ■ Step 1: Align It aligns the pelvis, which is tilted due to sitting habits and everyday posture, by navigating. By sitting so that you touch the backrest, the balance around the pelvis is aligned. High-resilience material is used, making it difficult to get tired even after sitting for a long time. ■ Step 2: Loosen By moving the pelvis back and forth, you can stretch the muscles and tendons around the pelvis that have become stiff, correctly aligning the unbalanced pelvis. A hard plate supports the movement, so anyone can easily do the back-and-forth exercise, which is usually difficult. ■ Step 3: Tighten By squeezing with the inner thighs, you can tighten the muscles around the pelvis and thighs, aiming to efficiently maintain the pelvis in the correct balance. You can exercise with the pelvis aligned, leading to an efficient and beautiful body line. ◎ There are no noticeable stains, but please understand that this is a used item before purchasing. ◎ There is no outer box or instruction manual.
