Hoist Fitness Leg Extension RS-2401

Hoist RS-2401 Leg Extension Machine for Sale

The Hoist RS-2401 is a selectorized leg extension machine built for commercial and light-commercial floors. It isolates the quadriceps from a seated position, and its back support rocks rearward through each rep instead of holding you still. It suits gyms, studios, clinics, and serious home builds.

• Product length—51.75" (131 cm)
• Product width—50.00" (127 cm)
• Product height—55.00" (140 cm)
• Machine weight—623 lbs. (283 kg)
• Floor anchoring—required, 4-1/2" bolts minimum
• Best fit—quad isolation, multi-user floors

What the Roc-It Motion Changes

The back support moves with you through the rep, and that single mechanical difference is what separates the RS-2401 from every fixed-seat station in its price band.

Almost every leg extension machine for sale today is built on the same premise: set the machine to fit, then hold still. Listings count seat positions. Coaching guides tell you to keep your glutes glued to the pad, grip the handles, pull yourself down, and drop a plate if your hips come up.

The hoist starts from the opposite end. The manufacturer's published specification says the RS-2401 begins in an upright posture and rocks rearward during the exercise and states that lowering the hips maintains a posterior pelvic tilt to better load the quadriceps. The pelvis isn't being pinned in place. It's being carried in a controlled direction, which Hoist also credits with a greater range of motion and a more natural hinge.

Why do my hips lift off the seat during leg extensions? Usually because the load is heavy enough that the hip flexors and lower back start helping. On a fixed frame, the answer is less weight or a better back-pad setting. Here the movement is engineered into the linkage instead. It's worth understanding before you compare this against anything else in the Hoist Fitness range.

Choose the RS-2401 if that rocking motion is what you want—not if you simply want a sturdier version of the machine you already train on.

Fit and Range Are Set Separately

Three separate systems handle fit here, so no single adjustment has to compromise between body size and range of motion.

The back pad is gas-shock assisted and moves to accommodate varying leg lengths, so changing it between users takes a hand rather than a shove. The roller pad self-aligns, and Hoist states this reduces potential stress on the ankle joints. Range of motion is its own control: a tapered pull-pin sets one of seven numbered start positions, marked on the frame so the setting can be recorded and repeated.

That separation matters more than the adjustment count. Setting up on a shared floor works best in a fixed order:

1. Set the back pad so the knee lines up with the marked pivot.
2. Let the roller find your lower shin without forcing it.
3. Pick a numbered range setting and note it for next time.

If you're new to the movement itself, the leg extension setup guide covers form before you spend anything.

Inside the Weight Stack

The RS-2401 carries a 270 lbs. (123 kg) selectorized stack, and Hoist's own parts list shows it isn't built from one plate size.

• Top weight—30 lb assembly
• Small plates—ten at 10 lb each
• Large plates—seven at 20 lb each
• Optional upgrade — RS-CAGE-NG-OPT1
• Stack with upgrade—275 lbs. (125 kg)
• Machine with upgrade—635 lbs. (288 kg)

Mixed plate sizes mean the jump between two pin settings isn't constant across the range. Anyone told that a stack always gives fine progression should check the increment at their actual working weight rather than assume it. The optional upgrade adds five pounds of selectable load and twelve pounds to the machine, which tells you it's a hardware assembly rather than a loose plate dropped on top. Comparable options sit across the selectorized leg machine range.

Delivery, Anchoring, and Assembly

This arrives as freight, builds on site, and has to be bolted down before anyone trains on it.

Anchoring is not optional. The hoist's owner's manual is blunt about the reason—an unsecured unit can tip. That requirement quietly rules out floating floors, and it means renters and upstairs rooms need a serious conversation before the order goes in. Assembly takes two people and a full hand-tool kit: sockets, an adjustable wrench, a hex key set, a rubber mallet, a tape measure, and a level. Check the shipping and returns terms before the truck is booked.

Can the RS-2401 sit flat against a wall? Not comfortably. Its width comes within a couple of inches of its length, which makes it closer to square than the long, narrow leg stations most rooms get planned around. Treat it as a corner or island piece.

Three Hoist Leg Extension Options

Three hoist machines here will run leg extensions at three different prices, and the cheapest of them covers the most movements—worth knowing before you commit.

Hoist RS-2401 Leg Extension

• Price—$5,226.00
• Movements—leg extension only
• Hoist line—Roc-It Selectorized
• Best fit—quad work on a moving seat

Hoist CL-3401 Club Line Leg Extension

• Price—$4,400.00
• Movements—leg extension only
• Hoist line—Club Line
• Best fit—dedicated station, lower spend

Hoist HD-3400 Leg Extension/Leg Curl

• Price—$3,960.00
• Movements—leg extension and leg curl
• Hoist line—Home and Dual
• Best fit—two exercises, one footprint

Two of the three cost less than the RS-2401, and one of those trains has hamstrings as well. Weigh that honestly against what your floor actually programs. The Club Line CL-3401 and the HD-3400 extension and curl combo both deserve a look before you decide.

Who It Suits and Who Should Skip It

A strong fit for:

• Floors where one station sees daily traffic
• Buyers standardizing on a single brand
• Clinics logging a repeatable start position
• Anyone adding a matching curl station later

Skip it if:

• You need two movements on one frame
• You expect to reconfigure the floor often
• Quad isolation isn't in the programming
• A four-figure station overshoots the room

Facilities building out a full leg section often pair this with the matching Leg Curl RS-2402 so both sides of the thigh get the same feel.

Frequently Asked Questions

Does the Hoist RS-2401 arrive assembled?
No. It ships disassembled and is built on site. The hoist specifies two people and standard hand tools, and the frame should be checked square and perpendicular once everything is together.

Is the RS-2401 covered when it's used at home?
Yes, but under commercial or light-commercial terms rather than a residential schedule. Hoist decides the tier by how the room is used, so confirm which applies to your situation before registering the warranty.

Are leg extension machines bad for your knees?
Not inherently for healthy adults training at sensible loads. Knee alignment with the machine's pivot and a controlled tempo matter more than the machine itself. Anyone with an existing knee condition should get clearance from a physician or physical therapist first.

Can I return the RS-2401 after it's set up?
Only within the published window, undamaged and back in its original packaging, with a restocking fee and return freight on the buyer. Equipment used beyond testing isn't eligible, so measure the room before it ships. A gym design consultation removes most of that risk upfront.

Why is this sold by private invoice?
Hoist orders here are quoted rather than run through standard checkout. That allows freight, configuration, and multi-station pricing to be handled properly on a machine of this weight and value.

Does Hoist publish a user weight limit for the RS-2401?
No user weight limit appears in the listing, the specification sheet, or the owner's manual. Rather than guess at a number, ask for written confirmation from Hoist if a specific limit is required for your facility.
