Commercial-grade leg extension + prone leg curl machine for complete quad and hamstring development in COMMERCIAL GYMS
The Muscle D Pro Strength Leg Extension / Prone Leg Curl Combo is built for busy commercial floors that demand fast training transitions, smooth performance, and rugged construction. This dual-function station lets members target the quadriceps with seated leg extensions and carve stronger hamstrings with prone leg curls—all in one premium machine.
Designed with a tough 11-gauge steel frame and a heavy-duty bearing system, the motion stays ultra-smooth and consistent under high-traffic usage. That fluid movement helps users maintain clean form, feel the working muscles through the full range, and train hard without a “sticky” or uneven rep.
Multiple quick, simple adjustments make it easy to dial in seat/back positioning and roller pad setup for proper alignment across a wide range of users. Whether your facility is serving athletes, general members, or strength-focused lifters, this Muscle D combo machine delivers the versatility and durability needed for serious lower-body training.
Quick Thumb Lever Leg & Roller Pad Adjustments
Set the range of motion in seconds using the thumb lever range adjustment. A second thumb lever makes it easy to move the roller pad into the ideal position so users can lock in proper alignment for stronger, more comfortable reps.
Dual-Function Design for Complete Leg Training
Leg extensions emphasize the quadriceps for knee extension strength and hypertrophy, while prone leg curls target the hamstrings for balanced posterior-chain development—perfect for well-rounded lower-body programming in commercial gyms.
Smooth, Controlled Motion Under Load
A premium bearing-driven movement system keeps the rep path fluid and consistent, helping reduce friction and improve training feel—ideal for athletes and members pushing progressive overload.
One Pop Pin Switch Between Movements
Move efficiently between leg extensions and leg curls with a single pop-pin adjustment. This fast transition supports smoother gym traffic flow and keeps workouts moving during peak hours.
Stabilizer Handles in Both Positions
Integrated stabilizer handles are available for both leg extension and leg curl setups, helping users brace properly for more controlled reps and stronger contractions.
Commercial-Grade Build for High-Traffic Floors
Built with 11-gauge steel for long-term durability, this machine is designed to thrive in commercial gyms, training studios, and performance facilities where equipment sees constant daily use.
