The Hoist RS-2602 Rotary Torso is a selectorized core station that trains trunk rotation from a kneeling position, with an adjustable chest pad and stabilizing handles. Hamilton Home Fitness sells it to commercial floors, studios, and serious home gyms that want a dedicated rotational station rather than a shared ab frame.
This is a single-purpose rotation station, not a multi-exercise core frame. You load it with a selector pin, set your starting angle, brace your chest against the pad and turn against resistance in either direction. It belongs to the Roc-It Selectorized line in the Hoist Fitness collection, which is the brand's pin-loaded commercial range.
What muscles does a rotary torso machine work on? Rotation is driven mainly by the obliques, with the deeper trunk muscles working to hold everything else still. The value of a machine is that it fixes your lower body so the turn comes from your trunk instead of your feet and hips.
Buyers weighing this against a crunch station should know the two do different jobs. Flexion machines fold you forward; this one turns you. If you want the full flexion-versus-rotation background and the plate-loaded comparison, that lives on our selectorized ab machines page. This page answers a narrower question: is this specific frame the right one for your floor?
Almost every rotary torso machine on the market seats you and pins your hips with thigh pads. The RS-2602 does not. You kneel on a pad, brace your chest, and hold stabilizing handles that Hoist states are there to support the upper body and minimize low back stress.
That single design choice decides more of the purchase than any spec on the sheet, and no listing spells it out. Even the closest alternative on our own floor, the BodyKore GR617 rotary torso, is a seated frame with a rotating base.
Here is what it means in practice. Every set begins by getting down onto the pad and ends by getting back up. On a mixed-ability floor, that is a real consideration before a five-figure order. The chest pad height adjusts, the start angle adjusts, and the load adjusts—the requirement to kneel does not.
Choose the RS-2602 if your users can kneel comfortably for a full working set. If that is in doubt, a seated or standing rotation station is the better buy, and no amount of adjustment on this frame will change it.
The RS-2602 gives you two motions from one frame. In ROC-IT mode the support moves with you, which Hoist describes as an instability option intended to increase muscle engagement. In LOCK IT mode the support is fixed, and the turn happens against a stable base.
Most Hoist stations sold through Hamilton Home Fitness give you the rocking motion and nothing else. This one lets you switch it off, which is why it works for two different training jobs on the same floor: locked for strict, heavier, repeatable sets, unlocked when you want the stability demand added on top.
✅ Kneeling brace keeps hips out of the turn
✅ Chest pad sets your bracing point
✅ Stabilizing handles steady the upper body.
✅ Lock the base for strict, controlled reps.
✅ Unlock it to add a live stability demand.
✅ Numbered starts repeat session to session
✅ Turns both ways from one setup
✅ Pin-selected load changes in one motion
✅ Optional kit raises the top of the stack.
✅ Equal footprint front-to-back and side-to-side
✅ Hand-tool assembly, no special equipment
✅ Wipe-down upholstery keeps upkeep simple
Hoist requires this unit to be bolted to the exercise floor with minimum 4-1/2 inch bolts, and warns that failure to do so may result in serious injury or death. Plan the position once, because it is permanent.
The equal footprint helps here: because the frame claims the same space in both directions, you can rotate it to any orientation in a floor plan without recalculating the space it takes. Review our shipping and returns terms before you order, since anchored commercial equipment is not a casual return. Ready to place it? Add the RS-2602 to your cart, or book a gym design consultation if it is going into a full build.
The same movement is sold in three body positions, and the position is the honest fork. Compare against the seated Hoist option and the standing alternative before deciding, and note that the Hoist Abdominals RS-2601 sits at the same price but trains flexion instead of rotation. If standing suits your users better, the Abs Company Standing Ab Twist is the on-floor comparison.
Rotation is under-trained on most strength floors, and a dedicated station is how facilities fix that without tying up a cable rig. This frame earns its footprint in a specific set of rooms.

Does the RS-2602 have a user weight limit?
Hoist does not publish one. It is absent from the product listing, the spec sheet, and the owner's manual, so we will not quote a figure we cannot source. Ask us and we will put the question to Hoist directly.
Will a rotary torso machine slim your waist?
No. Loaded rotation builds the muscles that turn and brace your trunk. Body composition is decided by overall training and diet, not by the movement pattern you choose.
Is loaded trunk rotation safe for your lower back?
Hoist states the kneeling pad and stabilizing handles are designed to minimize low back stress, and that is the manufacturer's design intent rather than a medical finding. Loaded rotation is a pattern to start light on and build slowly. Hoist's own manual advises consulting a physician before beginning any exercise program, and anyone with a diagnosed spinal condition should get clearance first.
Will it fit through a standard doorway?
Hoist publishes no crate dimensions for this frame. It ships as a kit and is built on site, so confirm delivery access with us before you order rather than measuring against the assembled height.
Can one person put it together?
No. Hoist specifies two people, plus a ratchet wrench with 1/2", 9/16", and 3/4" sockets, an adjustable wrench, a rubber mallet, a tape measure, a level, and an SAE hex key set.
Does the warranty cover home use?
Hoist's current schedule places the RS line in the commercial and light commercial columns: ten years on body and frame, five on structural moving parts, three on bearings, bushings and pulleys, and one year on finish, cables, upholstery and accessories. Light commercial means no membership dues and no more than 50 users per day. Cover applies to manufacturer defects only, is not transferable, and you pay freight on warranty parts.
