A RitFit PLC01 vs Mustang PRO comparison comes down to one question. Do you want the lowest cost 2-in-1 leg extension and curl station, or do you want a lever that changes how heavy your plates feel without unloading the weight rod?
This guide compares the RitFit PLC01 Leg Extension Curl Machine and the RitFit Mustang PRO Leg Extension Curl Machine on price, load ratio, capacity, padding, and setup, so you can pick the right one for a garage gym before you order.
Quick Answer: The RitFit PLC01 vs Mustang PRO choice is about load control and price. The PLC01 is the lower cost 2-in-1 leg extension and curl machine with one fixed 0.66x ratio, while the Mustang PRO adds four adjustable ratios from 0.8x to 1.3x, a 550 lb user rating, and thicker padding.
Key Takeaways
- Lower cost pick: The RitFit PLC01 is listed at $419.99 with one fixed 0.66x load ratio, a 325 lb maximum user weight, and a 109 lb assembled frame.
- Upgrade pick: The RitFit Mustang PRO is listed at $569.99 with four pull pin ratios from 0.8x to 1.3x and a 550 lb maximum user weight.
- Same job, one footprint: Both are 2-in-1 plate loaded machines that switch between seated leg extensions and lying leg curls with a pull pin.
- Plate format: Both machines take 2 inch Olympic plates only, so the plates you already own carry over to either unit.
- Buying signal: Choose the PLC01 for a strict budget and a compact corner, and choose the Mustang PRO when you want adjustable resistance, thicker padding, and more rated capacity.
What Is the Difference Between the RitFit PLC01 and Mustang PRO Leg Machines?
The RitFit PLC01 and the RitFit Mustang PRO differ mainly in price, load ratio control, and rated user weight. The PLC01 keeps one fixed 0.66x lever ratio at $419.99, while the Mustang PRO moves between four pull pin ratios from 0.8x to 1.3x at $569.99.
- Price gap: The $150 difference buys the adjustable ratio system, a 550 lb user rating instead of 325 lb, and thicker contact padding.
- Load control: Four ratio positions fine tune how heavy your plates feel, while the PLC01 holds one fixed setting.
- Frame weight: The PLC01 frame weighs 109 lb and the Mustang PRO weighs 150 lb, so the lighter unit is easier to move into a tight corner.
- Training range: Both are 2-in-1 stations covering seated leg extensions and lying leg curls, so neither machine locks you into a single movement.
Both units sit in the same RitFit leg machine family, so the choice is about the resistance system and the budget rather than the type of training you can do.
"The leg curl/extension machine exceeded my expectations, and I wish I'd gotten it earlier. Many adjustment options make it easy to dial in; the leg curl works well, and it's easy to get a solid workout. The compact size made this a perfect fit for my home gym. Good quality as well."

What Does the RitFit Mustang PRO Leg Extension Curl Machine Offer?
The RitFit Mustang PRO Leg Extension Curl Machine is the adjustable option of this pair. It carries four load ratios, a 550 lb user rating, and 60 mm padding on every contact surface.
- Durability: A 400 lb plate capacity and a 550 lb rated user weight sit on a 50 x 70 mm main tube with an X frame load bearing section and a 48 inch wide base.
- Versatility: The machine covers seated leg extensions, lying leg curls, single leg work on both, plus band peg resistance for accommodating load.
- Load control: The pull pin slides across 0.8x, 1.05x, 1.15x, and 1.3x while you stay seated, so a drop set becomes a pin move instead of a plate swap.
- Comfort: Wide 60 mm seat and back pads plus 4.80 inch rollers spread pressure during heavy sets.
The ratio system is the real story, because lever position and movement speed both change the torque your knee works against on a leg extension.[1] A study on a modified leg extension machine measured that joint torque and angular velocity relationship directly.[1]
"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."

What Does the RitFit PLC01 Leg Extension Curl Machine Offer?
The RitFit PLC01 Leg Extension Curl Machine is the lower cost option of the two. It keeps one fixed 0.66x ratio, a 375 lb plate capacity, and a 109 lb frame, and its listing displays an overall rating of 4.7 out of 5 from 468 reviews.
- Durability: A 50 x 70 mm main tube and a 325 lb rated user weight suit steady plate loading rather than maximal loading.
- Versatility: One machine covers leg extensions, lying leg curls, single leg variations, and the hip thrust and calf raise positions buyers describe using.
- Fit: A 4-position backrest angles independently of the seat, which helps shorter and taller lifters find knee to pivot alignment.
- Style: The same frame also ships as the RitFit Pink PLC01 Leg Extension Curl Machine for buyers matching a color scheme.
The fixed ratio is the tradeoff. Buyers who load close to capacity note that the pulley ratio eats plates faster, which matters more when every set needs another pair on the rod.
"Small area big punch. Foot print fits perfect to be able to unlock additional at home leg workouts."

How Do You Train Quads and Hamstrings on Either Machine?
Leg extensions and leg curls follow the same setup rules on both machines. Align the knee with the pivot point, control the lowering phase, and add load only when you own the full range of motion.
- Leg extension setup: Set the backrest so the knee sits level with the pivot, place the roller just above the ankle, and finish each rep without slamming into lockout.
- Lying leg curl setup: Keep the hips down on the pad, set the roller above the heel, and bring the pad close to the glutes on every rep.
- Single leg work: Training one limb at a time exposes side to side differences that a two leg set can hide.
- Progressive overload: Small plate jumps beat jumpy loading, and the four ratio positions on the Mustang PRO make those jumps smaller.
A trial found that drop set loading on the leg extension produced quadriceps growth that was not uniform across regions of the muscle, which is a reminder that variation is a tool rather than a substitute for controlled reps.[2]
"Always start from a fully extended knee and always bring the pad to touch your butt with each rep. If you can't touch the pad to your butt, it doesn't count as a rep unless you're purposefully training lengthened partials."
Dr. Mike Israetel, PhD, PhD in Sport Physiology, Renaissance Periodization, Complete Hamstring Training Guide
Is the Adjustable Load Ratio Worth the Extra Money?
The Mustang PRO costs $150 more than the PLC01 and adds four load ratio positions. It also carries 225 lb of extra rated user weight and 13 mm of extra pad thickness, which is either the point of the machine or pure overhead.
- Worth it for heavy loading: A 550 lb user rating and a 400 lb plate capacity leave more headroom than a 325 lb rating and a 375 lb capacity.
- Worth it for drop sets: The pull pin switches ratios in seconds without unloading plates, which is the fastest way to cut resistance inside a set.
- Worth it for shared gyms: Four ratios let a lighter and a stronger lifter use one machine on the same plates.
- Not worth it on a tight budget: If your plate loading stays moderate and you train alone, the PLC01 delivers the same two movements for less.
Skip the upgrade if the largest plate jump on your rod is already your ceiling and you rarely train close to failure. Pay for it if you want to reduce resistance mid set, or if two people of different strength share one machine.
Which RitFit Leg Machine Should You Buy?
Choose the RitFit PLC01 when the budget is the deciding factor and the machine sits in a compact corner. Choose the RitFit Mustang PRO when you want adjustable resistance and more rated capacity for heavy plate loading.
| Lifter profile | Recommended RitFit machine | Why |
|---|---|---|
| First home gym on a strict budget | RitFit PLC01 | Lowest entry price, 109 lb frame, 375 lb plate capacity |
| Lifter loading heavy plates every week | RitFit Mustang PRO | 550 lb user rating and 400 lb plate capacity |
| Solo lifter running drop sets | RitFit Mustang PRO | Pull pin ratio changes without reloading the weight rod |
| Household with mixed strength levels | RitFit Mustang PRO | Four ratios let two lifters share one plate stack |
| Garage built around a pink setup | RitFit Pink PLC01 | Same frame and load ratio in the pink colorway |
Recommendations compare RitFit machines only and follow the listed specifications rather than third party ratings.
Isolation work is not the whole leg day, though. A randomized controlled trial in physically active women found that single joint and multi joint resistance exercises produced exercise specific strength adaptations, so compound work still belongs next to whichever machine you pick.[3]
If that means adding a compound station later, both the RitFit Gazelle Pro 3-in-1 Leg Press and Hack Squat Machine and the RitFit BLP01 3-in-1 Leg Press and Hack Squat Machine cover the press and squat half of the session.
What Are Your Long-Term Upgrade Options?
Both machines are entry points into a leg training stack rather than dead ends. RitFit sells matching leg day pieces, so the upgrade path is about adding compound work and accessories instead of replacing the machine you already own.
- Bundle path: RitFit The Ultimate Leg Day Duo pairs a leg press and hack squat machine with a leg extension and curl machine in one order.
- Accessory path: The RitFit Cougar Leg Adduction and Abduction Machine adds hip work, and the RitFit BE01 Adjustable Back Extension Machine covers the posterior chain.
- Rack owner path: If you already run an M2 or M1 PRO rack, the RitFit LEM2 Leg Extension Rack Attachment or the RitFit LHM1 Leg Holder Attachment for M1 Pro can cover isolation without a second frame.
- Loading path: Both machines are plate loaded, so an Olympic plate set and a bench usually come next if you do not own them.
Bundles and promotions shift through the year, so treat a bundle as a convenience purchase and compare the current listings before you commit.
How Do You Set Up Either Machine Safely?
Setup on both machines comes down to four checks before your first heavy set. Line the knee up with the pivot, choose the seat and backrest angle, set the roller height, and confirm the plate load against the listed capacity.
- Knee to pivot alignment: The knee joint should sit level with the rotating cam, which keeps the loaded range centered on the joint instead of the shin.
- Seat and backrest: The Mustang PRO synchronizes three seat and backrest positions with a 15 degree hamstring tilt, and the PLC01 uses a 4-position backrest that moves independently of the seat.
- Roller height: Above the ankle for extensions and above the heel for curls, so the pad never presses into the shin bone or the Achilles.
- Plate limits: Stay inside 400 lb on the Mustang PRO and 375 lb on the PLC01, and start with the 0.8x ratio on the Mustang PRO while you learn the movement.
Stop the set if the knee feels pinched rather than loaded, then reset the seat before you add weight again. Neither machine replaces a warm up, so give the knees a few light sets before the working weight.
FAQs About the RitFit PLC01 vs Mustang PRO
Which RitFit leg machine is the better budget pick?
If your ceiling is a strict budget, the RitFit PLC01 at 419.99 dollars is the better fit, because it still delivers a 2-in-1 leg extension and leg curl station. The Mustang PRO sits higher at 569.99 dollars and adds four pull pin load ratio settings.
What do the 0.66x and 1.3x load ratios mean on these leg machines?
A load ratio changes how heavy the plates feel through the lever arm. The PLC01 uses one fixed 0.66x ratio, so each plate feels lighter than its face value. The Mustang PRO switches between 0.8x, 1.05x, 1.15x, and 1.3x with a pull pin while you stay seated.
Can the PLC01 and Mustang PRO handle heavy leg extensions for taller lifters?
Height range matters more than raw capacity for most buyers. RitFit lists the PLC01 for users from about 5 feet 2 inches to 6 feet 2 inches, while the Mustang PRO covers roughly 5 feet 1 inch to 6 feet 5 inches. Taller lifters should check knee to pivot alignment.
Do both RitFit leg machines use 2 inch Olympic weight plates?
Yes. Both the RitFit PLC01 and the Mustang PRO are plate loaded and built around 2 inch Olympic plates, so you can reuse the plates from your existing home gym setup. One inch standard plates do not fit the load bar on either machine.
Which of the two machines is easier to assemble in a garage gym?
Both arrive as partial assemblies with printed manuals and video walkthroughs. Verified buyers of the PLC01 describe roughly an hour of straightforward assembly, and Mustang PRO owners report a similar single person build. Two people still make lifting the main frame easier.
Can you train quads and hamstrings on the same leg machine?
Yes. Both machines switch between seated leg extensions for the quadriceps and lying leg curls for the hamstrings using a pull pin. That 2-in-1 design means one footprint covers both sides of leg day, and both support single leg work to even out side to side differences.
How much floor space does each leg machine need in a garage?
The Mustang PRO trades a wider 48 inch base for more stability under heavy loads, while the 109 pound PLC01 frame is the lighter and more compact of the two. Measure your ceiling and clearance before ordering, and leave room behind the roller for full knee extension.
Conclusion
The RitFit PLC01 vs Mustang PRO decision is a budget decision first and a feature decision second. Both are 2-in-1 plate loaded leg machines covering quadriceps isolation and hamstring curls from one footprint.
Pick the PLC01 at $419.99 if the price ceiling matters most, and pick the Mustang PRO at $569.99 if you want four load ratios and a 550 lb user rating. Check the current RitFit discount guide before ordering and confirm the live spec sheet for your space.
