Supine Sit-Up Automatic Rebound Board - Abdominal Exercise Equipment (Foldable)

Automatic rebound spring mechanism - assists you on the way back up; reduces strain on lower back and neck during sit-ups

Ergonomic curved handle grips - grab handles on sides provide stability and assistance during sit-up movements

Supine design (lying down) - work core muscles through controlled sit-up motion; spring assists return to starting position

Foldable, compact storage - 410mm x 1060mm x 70mm footprint folds flat; fits under beds or in closets when not in use

Sweat-absorbent surface - textured, non-slip material prevents sliding during workouts; stays grippy when wet

Built-in timer function - track workout duration; monitor sets and rest intervals

Lightweight portable design (3.95kg) - move between rooms or take to gym; includes carrying/storage mat

Best used 20-30 minute sessions, 3-4 times weekly for core strengthening. Start with light hand grip assistance (full spring support) and progress to reduced hand support as core strength improves over 2-3 weeks. Perform 10-15 reps per set, 3-4 sets per session. Lie on board with knees bent, feet secure, and perform controlled crunching sit-ups.
