4. Operating Instructions
The LVLC machine is designed for effective hamstring isolation through a prone leg curl exercise.
Performing a Leg Curl:
- Positioning: Lie prone (face down) on the V-bench, ensuring your knees are just off the edge of the bench and aligned with the machine's pivot point. Your torso should be flat against the bench.
- Foot Roller Adjustment: Adjust the foot rollers so they rest comfortably and securely against your lower calves, just above your ankles. The adjustable foot rollers accommodate users of all sizes, ensuring a personalized fit.
- Grip: Grasp the side handles firmly for stability and to maintain proper body alignment throughout the exercise.
- Execution: Exhale and slowly curl your legs upwards, bringing your heels towards your glutes. Focus on contracting your hamstrings. Maintain control and avoid swinging your legs.
- Return: Inhale and slowly lower your legs back to the starting position, maintaining control and resisting the weight. Do not let the weight plates crash down.
- Repetitions: Perform the desired number of repetitions, ensuring smooth and controlled movements.

5. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your Body-Solid LVLC Leverage Leg Curl Machine.
- Cleaning: Wipe down the frame and upholstery with a damp cloth after each use to remove sweat and dust. Use mild soap and water for deeper cleaning, avoiding harsh chemicals that may damage the finish or upholstery.
- Inspection: Periodically inspect all nuts, bolts, and moving parts for tightness. Tighten any loose fasteners immediately. Check the upholstery for any tears or excessive wear.
- Lubrication: The sealed bearing pivot points are designed for smooth operation and typically do not require lubrication. However, if you notice any squeaking or stiffness in the movement arm, consult a qualified technician or the manufacturer's support for guidance.
- Storage: Store the machine in a dry, climate-controlled environment to prevent rust and material degradation.
