Red Velvet member Yeri recently shared her pilates workout routine on SNS, revealing her toned physique while wearing a fitted black pilates jumpsuit. She showcased two key exercises using pilates equipment. The first is a side stretch and side extension movement on the Ladder Barrel, which strengthens the oblique muscles, rectus abdominis, and improves hip flexibility. This exercise effectively corrects posture and creates a slim, toned body by elongating the waistline and pelvic area. The second exercise is a modified Reformer Arabesque that builds balance and core strength. Experts note these pilates movements help alleviate stiffness in people who sit for extended periods while improving pelvic flexibility and spinal stability. However, those with lower back disc issues or hip problems should perform these exercises under professional supervision.
