The Warrior Commercial Series Prone Leg Curl is a professional-grade solution for prone leg curls. Through extensive biomechanical testing, we've discovered the optimal hip flexion angle that minimizes lower back stress while maximizing hamstring training effectiveness. Additionally, the ingenious multi-position adjustment disc and joint pivot design ensures every user can find their optimal movement pattern.
Features
- Adjustable Start Positions: Easily customize your workout with adjustable start positions that fit your body perfectly, adding comfort and better workout control.
- Comfortable Support Pads: Divergent chest and hip pads are designed to minimize back strain, keeping you stable and comfortable throughout your exercise.
- Customizable Calf Pad: The calf pad adjusts to fit different leg sizes for a secure and personalized hold during every rep.
- Durable Heavy-Duty Frame: Made with heavy-gauge flat oval steel tubing and finished with a high-quality electrostatic powder coat, ensuring strong, long-lasting durability.
- Smooth and Quiet Operation: 5mm coated steel cables combined with fiberglass-reinforced pulleys deliver a smooth, noise-free workout experience.
- Easy and Safe Adjustments: Intuitive, color-coded push-pull pins and quick-release seat levers make it simple and safe to change settings quickly.
- Convenient Storage Trays: Integrated trays provide handy storage for water bottles and accessories, keeping everything within easy reach during workouts.
Target Muscles
- Hamstrings: The primary muscles targeted are the hamstrings, including the biceps femoris, semitendinosus, and semimembranosus, which are key for bending the knees and extending the hips.
- Calf Muscles: This machine also works on the calf muscles, mainly the gastrocnemius and soleus, helping to improve lower leg strength and stability.
- Focused Isolation: Designed to isolate and engage these muscle groups effectively, the SA015D allows for deep, targeted workouts to build strength and tone your legs.
- Ergonomic Design: Ergonomically crafted to reduce strain on your lower back while maximizing muscle engagement, providing a safe and comfortable exercise experience.

Robust and Durable, Value-Optimized Choice
The main frame utilizes Q235A high-frequency cold-rolled steel, with 40*140mm square tubing and 50*100mm oval tubing working in harmony to ensure machine durability. Surface finishing employs electrostatic powder coating, passing over 800 hours of salt spray and impact testing. The finish is brilliantly aesthetic while the machine remains incredibly durable.

Precision Adjustment, Biomechanical Excellence
Extensive biomechanical testing has created the perfect synergy of 7-position ankle adjustment and 6-position knee adjustment systems. These two systems ensure every user, regardless of flexibility or body type, experiences custom-fitted training sensation.

Optimal Hip Flexion Angle, Zero Back Stress
The optimal hip flexion angle is the result of thousands of biomechanical experiments. This angle allows the body to perfectly nest within the foam padding, achieving the most compatible support effect while minimizing lower back stress for safer and more efficient training.

Large-Scale Testing, Optimal Stability
Through extensive testing, we've identified the optimal arm support position and upper handle curve angle, providing users with the most comfortable support stability. This effectively reduces support-related fatigue, keeping focus purely on hamstring training.
