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.
  • Ergonomic Comfort: High-quality padding reduces strain and enhances comfort during use.
  • Compact Footprint: Ideal for home gyms or commercial spaces, offering maximum functionality in minimal space.
