Main effects • Powerful shaping: Sculpting the waist, abdomen, hips, thighs, shoulders, and back lines to create tight "long muscles." • Core strengthening: Activate the deep core to improve lower abdominal protrusion, lower back pain, and backache. • Posture correction: Improve rounded shoulders, hunchback, forward head posture, and anterior pelvic tilt. • Low-impact safety: Joint-friendly, suitable for rehabilitation, postpartum, beginners, and people who sit for long periods.

Using the resistance of the springs and the instability of the bed surface, force the body to continuously engage the deep core muscles (transverse abdominis, pelvic floor muscles, multifidus) to stabilize the body and control the sliding. Throughout the process, emphasize: precise force application + breath coordination + body control.
