Adjustable Load Ratio for Custom Intensity
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 multi-bearing and linear-bearing components 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.

Quiet, 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.
Wide 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.
Premium 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.

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.
Absolutely. The adjustable load ratio makes it easy to start with very light effective resistance, which is perfect for users of all levels. The guided motion also ensures safe and proper form.
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 extra-wide seat and back pads are 2.4 inches (60mm) thick and upholstered with vinyl upholstery over high-density foam. The extended leg roller is also generously padded for secure and 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.

Customer Reviews
Overall rating: 4.6 / 5 from 22 reviews.
Definitely an upgrade from the last leg machine. Some cosmetic damage on the paint but nothing I can’t deal with. So far everything feels smooth. Haven’t tried the laying leg curls. I’m short so those have always been an issue for me.
Easy set up! Using it is even easier! Honestly I’d compare it to a piece of equipment you’d find in a commercial gym! So smooth and easy to change weight and configurations between leg extension and leg curl. I’m very happy with my purchase that’s why I decided to review it.
Just what I was looking for. Works Great
definitely an upgrade from the first leg extension machine, smoother and thicker and bigger all around
My honest review of the RitFit Mustang PRO Leg Extension Curl Machine. Putting it together really straight forward, instructions were very clear and understandable, took maybe an hour to assemble. Using it, I really like it, comfortable, and smooth. Leg extension gives you the perfect stretch and contraction for your quads and you can really load it up in weight. Hamstring curls are no different, seat positioning is great and you can position to get that full stretch. Also, no wobble, doesn’t feel like it’s going to tip over with the added weight plates. The leg extension pad, is a love/hate type thing, love that it swivels so you’re not fighting on positioning and rolls when it needs to and plenty of pad for comfort. Hate also that it swivels and doesn’t lock in, as I said it’s a love/hate but mostly love. Highly recommend this machine over their first release.
The first model was highly rated on YouTube. I decided to go with the upgraded model on blind faith. I am so glad I did. The range of motion on the device is amazing. The padding is great. The materials used are fantastic. I would recommend installing the weight holder during step 2. Its incredibly harder to get install it later as you have to lift the entire machine to install. I rate this 5 stars.
Functionality of it feels good! Sturdy and strong. A little upset a few pieces came damaged. One of the pieces didn’t line up with another piece and took a little elbow grease getting it into place. Overall happy with the machine. I do wish the seat and back cushion was a little more adjustable. I’m taller and leg extensions aren’t the most comfortable
RitFit mustang pro leg extension. Seated quad extensions and laying hamstring curls. Adjustable plate to fraction the weights resistance. Adjusts to 0.8, 1.05, 1.15 and 1.3. Easily adjusted with plates on it.
The Mustang pro is a great add to any gym. It does everything you need plus more, might be the best bang for your buck piece of equipment for your home gym. Don't hesitate to buy this, worth every penny. Only thing I'd complain about is they didn't offer a black and red combo.
Hi! Overall, the machine is great and better than expected. Only issue I have is the lower right hand bolt for the back pad won't tighten up. I've swapped out with other bolts and it's an issue with the insert in the pad itself. All of the bolts work as they should.
I took a gamble on this and purchased it before it was released. This is the best piece of home gym equipment I have ever purchased. I would change a couple things about the assembly manual to make things slightly easier, but, overall it was easy to assemble, which took about 90 minutes. After throwing on some weight, it felt like I was on a piece of equipment at a gym. This is as close to gym quality as you can get. It's hard to believe what you get for the price. The pads on the seat are perfect, as well as the leg pad. The thing is quiet as a mouse and is perfectly smooth throughout the entire movement. I've waited for years to add leg equipment to my home gym, and this is the perfect addition. Do not hesitate to buy this machine.
Love the moving leverage addition to this machine. It allows me to work past failure. Ergonomics of the machine are spot on. Extremely happy with this purchase
Really smooth and great quality especially for the price. It filled a gap in my garage gym.
It feels really good and gets the job done the way it should. My only gripe on the machines I get from ritfit is they come with damaged. They need to be able to packaged things better then they do getting something new but already has cuts in the grips or dents and dings through out the metal is just annoying
I love this machine. Surprisingly great and easy to follow instructions and quality materials. Motion is smooth, comfortable and ergonomic. Very well done!
I pre-ordered the Mustang Pro leg extension machine before there was any real world reviews that I could find. It has the features I was looking for at the price point I wanted for my home gym. Great value for what you get. The pre-order took longer than advertised to ship, but I knew that was a risk when ordering and RitFit communicated and delivered on a follow-up date. The unit came about as assembled as possible, and the rest of it was super easy to put together, took about an hour. I think they went above and beyond on the build. A lot of parts that could have been bushings they actually used bearings. The welds and paint all look great (which is sometimes hit and miss with home equipment). Overall operation is super smooth and user friendly. Nice even weight curve, quiet and full range of motion. It is smooth and easy to switch between extension and curls, super solid in both positions. Super happy with it, highly recommend. My only improvement would be some way to adjust where the pad hits your shin.
Just finished my first leg workout using this machine, and am very impressed. Extremely stable, even with lots of weight. You can also do hip thrusts and calf raises on it
The product was damaged in shipping. The chrome RitFit logo was dented. It arrived 3 weeks late. My third RitFit, and last, purchase. Not a fan!!!!
As advertised
Great machine and instructions to build were super simple! This sucker is SOLID and heavy. I got it together and hit a legs workout that same day and it felt great. The simplicity of the machine makes this a great garage gym addition.
4/5 stars. Customer service was very responsive. Leg extension works great once I got it put together, but they sent the wrong part initially which delayed everything. To their credit, they did send the correct one and got it resolved. Do yourself a favor and inspect every part before you start assembly so you’re not halfway through and realizing something is off. Just be aware you might have to follow up if something is bent due to poor packaging. Overall, it worked out in the end.
