Selectorized Seated Leg Extension & Leg Curl Machine w/ 250lb weight stack (New)

The SFE Selectorized Seated Leg Extension & Leg Curl Machine w/ 250lb weight stack combines two of the most biomechanically effective lower-body isolation movements into one heavy-duty, compact machine - giving you the ability to isolate and overload both quads and hamstrings in a single footprint.

Key Features & Adjustability:

• Fully adjustable back pad moves forward and backward to fit a wide range of users, tested on users as short at 4'10" and as tall as 6'10"!
• Extended seat pad and additional back pad position stops to better accommodate taller lifters and those with longer legs.
• Leg roller movement arm with 9 starting positions, plus leg roller adjustment with 5 positions, for dialing in perfect setup on both movements.
• Knee / thigh pad adjustment with 8 secure starting positions for seated leg curls, plus comfortable rubber grip handles for added stability.
• Laser-engraved numbering on the movement arm, roller, and thigh pad for easy, repeatable position recall.

These adjustments allow you to train both movements through a full or partial range of motion, depending on your body type and training goals.

Performance & Build:

With a smooth, consistent tension curve and heavy-duty construction, this machine delivers commercial-grade feel and performance. Textured rubber grips on both movements provide security and comfort through even your heaviest sets. Every machine ships with the maximum-capacity 250lb weight stack at a 1:1 pulley ratio, giving you all the resistance you need right out of the box.

Compact Footprint:

Despite its versatility and heavy-duty build, the machine fits easily into a home gym or training studio and delivers big gym functionality in a manageable footprint. (See dimensions panel in the photo gallery for minimum and maximum dimensions across all positions.)

Key Features:

• Dual Functionality: Supports both leg extensions and seated leg curls for a complete lower-body workout.
• Selectorized Weight Stack: Easily adjust resistance with a simple pin system for quick weight changes.
• Adjustable Design: Accommodates different user heights and exercise preferences.
• Durable Construction: Heavy-duty steel frame with a sleek finish ensures long-lasting performance.

Is this commercial quality or residential quality?

Our products are 100% commercial grade and are in use in many boutique commercial gyms across the US. By making combo machines and sticking to the steel, we keep the cost low and make it affordable for residential users.

Can I add additional weight to the machine?

No, our machines are at maximum but you can add accessories to increase weight or resistance.

How do I maintain this machine?

Our machines need very little maintenance. We recommend white lithium grease to lubricate the moving parts on an as needed basis (based on usage). Once per year we recommend re-tightening all the bolts to prevent unnecessary wear & tear.

Arrives in one box. Includes all parts for full assembly; frame, pads, weight plates, pins, hardware & instruction manual.

SFE machines are heavy-duty, commercial-grade equipment designed for serious training, and they require proper tools and at least two people for assembly.

They arrive in wooden crate on a pallet. Our machines are built for heavy duty use and demand time and effort to set up correctly. We provide detailed assembly manuals for every model, but please be prepared for the process.

Although the majority of our customers are able to assemble the machines themselves, if you are not experienced with equipment that involves bearings, guide rods, weight stacks, and/or heavy frames, we strongly recommend hiring a local fitness equipment technician.

Companies such as Fitness Machine Technicians typically charge $200 to $400 per machine, which can save you 2 to 6+ hours, depending on your tools and experience.

Please note that we do not offer assembly services outside of the Phoenix metro area, as hiring locally is usually faster and more cost-effective, and we prefer to pass those savings on to you!
