💪 Why Fitness Enthusiasts Are Switching to Spring Resistance

🔥 Full Upper-Body Activation – All in One Motion

Unlike basic arm exercisers, the U-Twist Pro’s U-shaped spring design engages multiple muscle groups simultaneously:

• 💓 Chest & Pecs – through controlled pressing and squeezing
• 💪 Biceps, Triceps & Forearms – via twisting and flexing motions
• 🧱 Shoulders & Upper Back – during stabilization and extension
• 🧍 Core & Thighs – when used in dynamic standing or squat positions

Includes a free training guide chart with illustrated exercises to maximize every rep.

🌐 3 Adjustable Resistance Levels

Choose your challenge:

• Level 1 (Light) – Ideal for warm-ups, rehab, or beginners
• Level 2 (Medium) – Perfect for toning and endurance
• Level 3 (Heavy) – Built for strength gains and muscle definition

All powered by high-strength metal springs with smooth, stall-free elasticity.

🛡️ Engineered for Safety & Comfort

• Soft leather outer casing prevents pinching or skin contact with metal
• Thickened anti-slip foam handles absorb sweat and reduce hand fatigue
• Stable, controlled resistance—no jerking, no risk of overextension
