Abdominal Crunch Trainer

Before using the Abdominal Crunch Trainer, fully warm up waist, abdomen, hips and lumbar ligaments to avoid strains. Train with standard movements: use abdominal core strength to curl your upper body, no lumbar inertia or neck compensation. Ensure your movement rhythm matches the Abdominal Crunch Trainer's fixed trajectory for safety.

Before use, adjust the Abdominal Crunch Trainer's seat height and backrest angle to your height/leg length. Keep your back fully fitting the cushion (no lumbar suspension), feet steady on pedals, hands holding handles naturally. Proper adjustment provides stable support and avoids excessive lumbar pressure.

When first using the Abdominal Crunch Trainer, start with the lowest resistance and 8-10 reps per set. Increase gradually after adaptation to prevent fatigue. Breathe steadily: exhale when curling, inhale when returning. Coordinate breathing and movement to boost effectiveness and avoid discomfort.

After training, don't leave the Abdominal Crunch Trainer immediately. Do static waist/abdomen stretches (e.g., twisting upper body, leaning forward) to relax muscles. Check the machine weekly: ensure counterweights are secure, knobs tight, slides smooth. Contact maintenance promptly if abnormal.

When customers report equipment problems, the after - sales team will respond within 12 hours and provide solutions within 48 hours. For complex problems, special personnel will follow up on a case - by - case basis to ensure that the use of the Abdominal Crunch Trainer is not interrupted.

For cooperative customers, inspections of the Abdominal Crunch Trainer are carried out every quarter to check structural stability, component wear, and safety performance, troubleshoot hidden dangers in advance, provide maintenance suggestions, and extend the service life of the equipment.

Remote guidance for simple troubleshooting is supported; for hardware overhauls and complex faults, on - site maintenance is provided within 48 hours within 200 kilometers, and efficient solutions are negotiated for over - distance situations.

An emergency reserve warehouse for commonly used spare parts is established, covering wearing parts. When receiving maintenance requests, suitable spare parts are allocated with priority to shorten the maintenance waiting period.
