The HOIST Fitness RS-2402 is a selectorized leg curl machine from the Roc-It line, built as a single seated station. The seat rocks rearward through each rep instead of locking your hips at one angle. It suits commercial floors, studios, and serious home gyms that want one dedicated hamstring station.
This is a pin-loaded hamstring station that does one job and nothing else. You sit, set the pin, and curl. There is no changeover pin, no second exercise, and no plates to load between sets.
That single-purpose design is why it sits in the RS Roc-It Selectorized family rather than in Hoist's dual or plate-loaded lines. If you want to see where it sits against the rest of the range, the HOIST Fitness collection covers every line the brand builds.
What muscles does a leg curl machine work on? Knee flexion against resistance loads the hamstrings, with some help from the calf muscle that crosses the knee. It is the direct counterpart to the quad work a leg extension gives you.
The RS-2402 does not hold your hip at a fixed angle. Hoist's specification states the machine begins in an upright posture, then rocks rearward during the exercise, lowering the hips into a posterior pelvic tilt to give a greater range of motion.
That matters more than any listing will tell you. Almost every article comparing seated and prone leg curls is built on one idea: a seated curl holds the hip flexed, which keeps the hamstring long at the start of the rep. Those comparisons test fixed-frame machines. They do not test a seat that travels.
So the honest position is this. The rocking platform is a real, documented mechanical difference from a fixed seated curl. What nobody can tell you is how it changes hypertrophy outcomes, because the studies everyone quotes never looked at it. Treat the ride as a comfort and range-of-motion feature, not as a proven growth advantage.
If you are still choosing between movement patterns rather than models, our guide to leg exercise machines covers how each lower-body station earns its floor space.
Measure this one as a square, not a strip. At 52.25 inches long by 50.00 inches wide, the frame is almost as wide as it is deep, which is unusual for a leg machine and changes how it sits in a room.
Work through it in this order before you order:
A long, narrow machine can be pushed flat against a wall to reclaim depth. A near-square one cannot. Add the 636 lb frame weight, and this is not equipment you slide across the room on a whim. Facilities planning a full-strength floor can book a gym design consultation before committing to a layout.
How much space does a leg curl machine need? Plan for the assembled footprint plus entry and service room on at least two sides. Ceiling height is rarely the constraint on a seated curl.

Warranty and ordering
Those warranty terms come from Hoist's own published schedule, which places the RS line in its commercial and light commercial columns. Related quad stations sit in our leg extension machine collection.
Before you buy a dedicated station, price it honestly against a machine that does two movements. Hoist builds one, and we stock it.
Choose the RS-2402 if hamstring volume is heavy enough to justify a station of its own. Choose the combo if two movements matter more than a bigger stack.
HOIST Roc-It Leg Curl RS-2402
HOIST Dual Series HD-3400
The HOIST HD-3400 Leg Extension/Leg Curl costs $1,266 less, adds a second exercise, and takes only about eight and a half more inches of length. What the RS-2402 buys instead is a larger stack, a purpose-built curl geometry, and no queue at the changeover pin.
At the home-gym end of the same decision, the Body-Solid GCEC340B CAM Leg Extension Curl covers both movements at a fraction of the outlay, with a lighter frame and less resistance headroom.

A strong fit if:
Look elsewhere if:
That third point is worth saying plainly. Hoist's residential warranty column does not list the RS line at all, so a home buyer receives commercial or light commercial terms depending on how the room is used. Buyers who want a lighter, home-rated option should look at the Body-Solid GLCE365B instead.
Hoist warrants this machine to the original purchaser only, against defects in workmanship and materials under normal use or service. Coverage applies to manufacturer defects, and Hoist reserves the right to change specifications, design, and function at any time.
Which warranty column applies depends on the room, not the model number. Commercial terms apply where a facility charges membership dues or the equipment sees more than 50 users a day. Light commercial terms apply to hotels, apartment buildings, training studios, and similar sites below that threshold.
Hamilton Home Fitness is an authorized hoist dealer and ships nationwide from our Tennessee headquarters. Because Hoist runs as a private invoice line, our team confirms freight and lead time with you directly rather than quoting a generic delivery window.
Check our shipping and returns terms before you order, particularly the packaging condition rules. On a 636 lb crate machine, the room measurement has to be right the first time.
Is the RS-2402 the same as the RS-2401?
No. The RS-2401 is the leg extension in the same Roc-It family, and it trains the quadriceps. The RS-2402 is the hamstring station. The two are frequently confused because they share a frame style and several published features.
Does the RS-2402 arrive assembled?
Hoist does not publish assembly requirements or crate dimensions for this model, so we cannot state them here. Confirm both with our team before delivery day, since the crate size decides your access route.
Can the 5 lb upgrade be added after purchase?
Hoist lists RS-CAGE-NG-OPT1 as an optional add-on weight system but does not publish whether it can be retrofitted later. Ask us to confirm with the manufacturer before you finalize the order.
What is the smallest weight jump on the stack?
Hoist publishes no increment size for this model. The only sub-step it documents is the optional upgrade, so plan progression around that if small jumps matter to your programming.
Why is the frame so much heavier than the stack?
On a selectorized machine, most of the mass is structure rather than resistance. That weight is what keeps the frame from shifting when a strong lifter finishes a hard set, and it is why the machine is rated for daily commercial traffic.
Do I need a leg extension as well?
Not necessarily. Squats and presses already load the quads heavily, while hamstrings often go undertrained. If your program already covers knee extension elsewhere, a dedicated curl station is the more useful addition.
Measure the room, confirm the access route, then place your order and let our team handle the freight from Tennessee. You get a commercial Roc-It station, Hoist's published warranty schedule, and an authorized dealer answering the phone if anything needs sorting after delivery.
