Additional Info

BENEFITS

• Progressive Strength Gains: Adjustable load supports gradual increases to safely build muscle and force output in arms, chest, and back.
• Improved Grip and Forearm Power: Targeted resistance enhances finger, wrist, and forearm strength for better performance in climbing, racket sports, and lifting.
• Enhanced Shoulder and Chest Development: Chest-expansion and pressing movements improve pectoral and deltoid strength and stability.
• Faster Rehab and Recovery: Controlled, low-impact resistance suitable for rehabilitation from hand injuries, tendonitis, carpal tunnel, and post-op recovery (with clinician guidance).
• Greater Joint Stability and Coordination: Multi-angle loading trains stabilizer muscles and improves neuromuscular control for athletic movements.

USAGE GUIDELINES

• Start Light and Progress: Begin at the lowest safe resistance (around 30 kg) to practice technique, then increase in small increments as strength improves.
• Control the Movement: Perform slow, deliberate concentric and eccentric phases avoid uncontrolled snapping or jerking motions to protect joints and springs.
• Rehabilitation Use: For therapy, follow a clinician’s protocol, use lighter resistance, higher repetitions, and focus on the pain-free range of motion.
• Pair With Other Exercises: Combine with push-ups, rows, kettlebell swings, or core drills for balanced upper-body conditioning.
• Safety Check: Ensure the magnetic lock is engaged and springs are secure before each set; never use if any component appears worn or damaged.

CARE INSTRUCTIONS

• Inspect Regularly: Before each session, check springs, locking mechanisms, and handles for wear, corrosion, or loose fittings.
• Cleaning: Wipe down handles and metal parts after use with a damp cloth, use a mild soap solution if needed, then dry thoroughly to prevent rust.
• Lubrication: Apply a light machine oil to pivot or cylinder contact points occasionally if you notice stiffness, wipe away excess oil.
• Spring Replacement: Replace springs immediately if any deformation, cracking, or loss of tension is observed; do not continue using damaged springs.
  
• Storage: Store in a cool, dry place away from direct sunlight and damp environments. Avoid leaving it outdoors where the springs can corrode.
