Pro Strength Adjustable Kneeling Leg Curl - Silver
Description
The Muscle D Fitness Pro Strength Adjustable Kneeling Leg Curl is a commercial-grade, iso-lateral plate-loaded hamstring machine built for gyms, training studios, and serious strength facilities that demand precision and durability. The kneeling design locks users into a stable position that drives superior peak hamstring contraction - something traditional lying leg curl machines simply cannot replicate. Each leg works independently through iso-lateral movement, ensuring balanced development and eliminating the risk of the stronger side compensating for the weaker one.
Constructed from heavy-duty 11-gauge steel with double-stitched commercial upholstery, this machine is engineered for demanding daily use without compromise. Commercial industrial bearings deliver a buttery-smooth, controlled feel through every rep, while quick pop-pin adjustments make switching between left- and right-leg training fast and effortless. Integrated plate storage and contoured grip handles round out a design that is as practical as it is performance-driven.
Key Features
- 11-Gauge Steel Frame: Heavy-duty construction built to withstand years of high-volume commercial use.
- Iso-Lateral Plate-Loaded Movement: Each leg trains independently, correcting strength imbalances and promoting muscular symmetry.
- Kneeling Design for Peak Hamstring Contraction: Positions the hamstrings in a shortened state at the top of the movement for a stronger squeeze and better muscle activation.
- Reduced Lower Back Stress: The kneeling setup stabilizes the pelvis, improving hamstring isolation and reducing the tendency to overextend the lower back under load.

- Quick Pop-Pin Left/Right Leg Switch: Seamlessly transition between unilateral training sides mid-session.
- Commercial Industrial Bearings: Deliver smooth, consistent motion through every rep for a premium training feel.

FAQ
What is the difference between a kneeling leg curl and a lying leg curl?
A kneeling leg curl places you in an upright kneeling position, which shortens the hamstrings at the top of the movement and creates a stronger peak contraction compared to the lying leg curl. It also stabilizes the pelvis more effectively, reducing unwanted lower back involvement and allowing for more targeted hamstring isolation. Many strength coaches prefer the kneeling design for serious hamstring development.
What does iso-lateral mean and why does it matter?
Iso-lateral means each limb operates independently - in this case, each leg curls separately rather than both legs moving together. This prevents your stronger leg from compensating for your weaker one, which is common on bilateral machines. Over time, iso-lateral training corrects strength imbalances, improves muscle symmetry, and reduces injury risk.
Does this machine require weight plates, and what size plates fit?
Yes, this is a plate-loaded machine, meaning weight plates are not included and must be added separately. The machine features 12" weight pegs on 4 storage horns and has a 10 lb starting resistance. Standard Olympic plates are compatible. The plate-loaded design gives you full control over resistance progression.
What assembly and delivery options are available?
Several delivery and installation options are available at checkout, including curbside delivery, garage delivery with no unpacking, warehouse pre-assembly, and full assembly and installation. Due to the size and weight of this machine (325 lb), freight shipping is used. If you need help choosing the right option for your facility, contact our team before placing your order.
What warranty does this machine come with?
The Pro Strength Adjustable Kneeling Leg Curl is backed by a 10-year structural warranty, a 3-year warranty on moving parts and wear items, a 1-year warranty on wear items, and 90-day coverage on paint, upholstery, cosmetic items, and labor.

Is there a weight limit for users on this machine?
