• 【100% Self-Powered – Train with Your Own Energy】

No motor. No electricity. No limits. The RJ401 runs purely on your movement, delivering a natural running experience while reducing energy consumption. The faster you move, the greater the challenge—perfect for efficient calorie burn and sustainable fitness.

• 【Dual Flywheel Resistance System for Real Performance】

Unlike basic flat manual treadmills, the dual flywheel design increases inertia and resistance, creating smoother motion and higher training intensity. Ideal for endurance building, fat loss, and strength conditioning.

• 【3-Level Adjustable Incline for Progressive Training】

Switch between three incline levels to simulate uphill walking or power running. Customize intensity to match beginners, rehabilitation users, or advanced runners without complex settings.

• 【Joint-Friendly 8-Point Shock Absorption】

Built with an 8-shock absorber structure and 5-layer anti-slip running belt, the RJ401 protects knees and ankles while maintaining stability. Wider running area (36.22” × 15.35”) ensures confident strides.

• 【Compact, Quiet & Space-Efficient Design】

Slim and lightweight frame fits easily into apartments or home offices. No motor means ultra-low noise—train anytime without disturbing family or neighbors. Supports users up to 330 lbs (150 kg).
