The Mustang PRO's innovative adjustable load-ratio system offers four distinct resistance settings, ranging from lighter to heavier (0.8×, 1.05×, 1.15×, 1.3×). Simply pull the pin to instantly dial in the challenge, with all four settings switching smoothly in seconds while you remain seated and without unloading plates. This gives lifters of all levels the ability to fine-tune every set, push past plateaus, make steady progress, and easily reduce resistance for true within-set failure training.
All-in-One Quad & Hamstring Station
Train both leg extensions and lying leg curls on a single, space-efficient machine. A simple pull-pin lets you switch between quad and hamstring modes in seconds, making it easy to run supersets, save space, and get more done in less time, all without changing equipment. Every movement also supports single-leg training, so you can isolate each side and help correct muscle imbalances.
Premium Comfort for Every Set
Extra-wide 2.36 inches thick seat and back pads, paired with large 4.80 inches diameter foam rollers, distribute pressure evenly so heavy sets stay comfortable and secure. Upgraded rubber grips, smooth cable travel, and band-peg compatibility complete the premium training experience.
400 lb Capacity & Rock-Solid X-Frame Stability
Built from heavy-duty 1.97 × 2.76 inches (50×70 mm / 14-gauge) steel tubing, the reinforced X-frame delivers exceptional rigidity and balance. The machine supports up to 400 lb of loaded weight and users up to 550 lb, providing a planted, confidence-inspiring feel that rivals commercial gym equipment.
Butter-Smooth Cable Motion
High-quality aluminum pulleys combined with multiple bearings and two linear ball-bearing guide rails create an exceptionally smooth resistance path. The result is fluid, controlled motion with minimal friction — helping protect your joints, improve control, and maintain consistent tension throughout every rep, without the dead spots and lockout drop-off that plague lever-only machines.
Ergonomic Adjustments for Any Body Size
The synchronized seat and backrest offer multiple adjustments: the first two settings optimize seated leg extensions with slightly different quad emphasis, while the third locks in a 15° incline for lying curls. This ergonomically tuned angle keeps your pelvis neutral, minimizing lower-back stress for peak hamstring isolation.
More Details
01Quiet, Home-Friendly Motion
Sealed pulleys and an optimized cable path minimize noise and vibration, making this machine ideal for garages, basements, or shared living spaces.
02Wide Stable Base for Heavy Lifts
The 48-inch-wide base and X-frame load-section keep all four feet planted under heavy loads — no sway, no creep, no rerack to recenter the bar. This is the kind of stability serious leg-day work demands when fatigue starts to bite at form.
03Premium Powder-Coated Frame
Thick-gauge steel with a durable powder-coat finish resists chips, scuffs, and rust, so your machine keeps looking new after years of sweaty workouts.
04Easy Plate Compatibility
A long weight horn fits 2-inch Olympic plates with room to grow. You simply slide on more weight as your legs get stronger.
05Comfort-First Touch Points
Rounded edges, soft vinyl upholstery, and foam-wrapped contact areas reduce pinching and pressure, so you focus on muscle burn — not joint discomfort.
06Embossed Grain Pad Surface
A finely embossed grain across the textured, easy-clean vinyl upholstery gives the seat and backrest a leather-like feel — grippy under sweat and crack-resistant where smooth vinyl fails over time.

The Mustang has a fixed 0.8x load ratio, while the Mustang PRO has four adjustable load ratios: 0.8x, 1.05x, 1.15x, and 1.3x. Both models support seated leg extensions and lying leg curls, with three synchronized seat and backrest positions. On either model, you can add or remove weight plates to change the training weight.
It's a 2-in-1 machine designed for two primary exercises: Seated Leg Extensions (targeting quadriceps) and Lying Leg Curls (targeting hamstrings). A quick pull-pin lets you switch between modes in seconds.
The weight rod can be loaded with up to 400 lbs of weight plates. The machine itself is rated for a maximum user weight of 550 lbs, thanks to its sturdy steel X-frame construction.
Instead of just adding plates, you use a 4-position pull-pin on the weight rod. Each position offers a different load ratio (0.8x, 1.05x, 1.15x, 1.3x), effectively changing how heavy the weight plates feel. This allows for quick drop sets, or fine-tuning without changing plates.
The seat and backrest are synchronized and have 3 preset angle positions. Simply move the adjustment lever to change both simultaneously for different exercise focuses and comfort.
Yes. You can adjust the training weight on either model by adding or removing plates and use the three synchronized seat and backrest positions to find a comfortable setup. The Mustang PRO also offers four adjustable load ratios; the Mustang's load ratio is fixed at 0.8x.
The Mustang PRO accepts 2-inch Olympic plates only. The 350 mm effective load-bar length, combined with the 4-position pull-pin slide mechanism, is engineered around Olympic-sized plate hubs and standard Olympic plate spacing. 1-inch standard plates are not compatible.
Among home leg machines, the load-ratio system here offers four positions ranging from 0.8x to 1.3x, versus the more common one fixed ratio or shallow three-position range found elsewhere. Pad thickness across all contact surfaces reaches 60 mm (2.36 in), which is the largest disclosed in the segment. The wide stance of the X-frame trades a larger floor footprint for greater stability under heavy loading.
Yes. The seat pad measures 17.7 (13.4) × 18.5 in [450 (340) × 470 mm], and the backrest pad measures 12.2 (11.0) × 24.0 in [310 (280) × 610 mm]. Both pads are 60 mm (2.36 in) thick with vinyl upholstery. The padded leg roller measures 20.1 in (510 mm) long and 4.80 in (122 mm) in diameter for comfortable support.
The machine is designed to accommodate users between 5 ft 1 in and 6 ft 5 in (1.55m - 1.95m). The adjustable seat and multiple pivot points ensure proper alignment for this height range.
Yes. In the leg curl position, the seat has a built-in 15 degree tilt. This forms a V shape with the back pad, helping to keep your pelvis neutral and lower back supported while pre-stretching your hamstrings.
No. The stable X-base frame and smooth aluminum cable pulley system are designed for quiet, stable, and jerk-free operation, even under heavier loads.
Assembly is straightforward using included hardware and instructions. Labeled parts and online manuals make the process easier.
