Hoist Fitness Triceps Extension RS-1103

Hoist RS-1103 Tricep Extension Machine

The Hoist RS-1103 Triceps Extension is a selectorized, single-station triceps machine from Hoist's Roc-It range. The user support starts in a slight forward lean and rocks rearward into the working position, following a seated bar-dip path. It suits home gyms, studios and commercial floors adding a dedicated arm station.

• Assembled footprint — 65.00" x 51.25" (165 x 130 cm)
• Product height — 54.75" (139 cm)
• Frame weight — 557 lbs. (253 kg)
• Resistance — selectorized pin-loaded stack
• Seat adjustment — ratcheting, seven positions
• Floor fixing — bolt-down required

What the RS-1103 Is Built to Do

This machine trains the triceps through a seated pressing path rather than a strict elbow-only extension. Hoist's own specification describes the motion as mimicking a bar dip, with adjustable exercise handles setting your arm position before the first rep.

That distinction matters more than most spec lists admit. A dip-pattern press lets you load the triceps heavily with your torso braced, which is why gyms keep one on the floor alongside a pushdown column. If you want the full picture of how the styles differ, the tricep extension machines category covers the whole range.

Hoist states that the adjustable handles reduce excessive shoulder stress and instability. Treat that as the manufacturer's design intent rather than a measured result — it is a positioning claim, not a clinical one.

Why the Foot Assist Pedal Matters

Hoist's parts list for this model includes an assist pedal assembly, and the machine carries its own dedicated foot-assist decal. That is unusual equipment on an arm station, and it changes what the last two reps of a hard set look like.

Every competing listing sells triceps machines on stack size, cam smoothness and steel gauge. None of them answers the question that actually decides a solo session: what happens when the weight stops moving and there is nobody behind you. A foot-driven assist gives your legs a way to contribute at the sticking point.

Be aware of one honest limit: Hoist publishes the pedal as equipment but does not publish how far it travels or how much load it offsets. Plan your working weight on what you can move unassisted.

Planning Floor Space and Anchoring

Measure the room before you order, because this is a wide station and it is meant to stay where you put it. The frame is heavy enough that repositioning it later is a two-person job at minimum.

How much clear floor space does this machine need? Add walking room on both sides of the stated footprint. You need entry space at the seat, clearance behind the stack for maintenance, and enough room to step off the pedal without hitting a wall.

Does a seated triceps machine have to be bolted down? For this one, yes. Hoist's owner's manual instructs you to bolt the unit to the exercise floor using minimum 4-1/2" bolts to prevent tipping, and warns that failing to do so may result in serious injury or death. That rules out floating floors, rental spaces and rooms where drilling is not an option.

Full Specifications

Everything below comes from the product sheet, the live listing and Hoist's own published documents. Where a detail is not published, this page says so rather than guessing.

Build and motion

• Model — RS-1103
• Line — Roc-It selectorized
• Movement — seated triceps extension
• Handles — adjustable exercise handles
• User capacity — not published by Hoist

Warranty and support

• Coverage — original purchaser only
• Scope — manufacturer defects only
• Frame and body — 10 years
• Structural moving parts — 5 years
• Bearings, bushings, pulleys — 3 years
• Finish, cables, upholstery — 1 year
• Transferable — no

Those terms are Hoist's commercial and light commercial schedule, which is the tier the RS line sits in. Hoist warrants the product to be free from defects in workmanship and materials under normal use or service, and reserves the right to change specifications, design and function at any time. Full terms sit under the Support link on Hoist's site.

Assembly and upkeep

• Build crew — two people
• Tools — sockets, wrench, mallet, hex keys
• Alignment — guide rods checked with a level
• Cleaning — no ammonia, acid or petroleum solvents

The machine ships with a commercial maintenance decal. Hoist publishes a separate, lighter home schedule, so a private buyer should follow that one instead of the daily commercial routine printed on the frame.

Who It Suits, and Who Should Skip It

A good fit if you:

• Train alone and push past the last clean rep
• Want a dedicated arm station, not a combo
• Own the floor and can anchor the frame
• Are equipping a studio or commercial gym

Look elsewhere if you:

• Want strict elbow-only isolation with the arm pinned
• Need one station to cover biceps and triceps
• Are working with a narrow or shared room
• Cannot drill into your flooring

Is a smaller weight stack a problem for triceps training? Rarely. The triceps work as a single-joint muscle here, and most lifters never approach the ceiling of a commercial stack on this movement. Footprint and seat fit will limit you long before the load does.

RS-1103 vs Two Hoist Alternatives

Three Hoist machines cover triceps work at different prices and footprints. The Club Line Triceps Extension CL-3103 runs the same movement on a fixed frame, while the Preacher Curl/Triceps Extension HD-3100 covers both arm groups on one unit.

Hoist RS-1103 Triceps Extension

• Price — $5,226.00
• Weight stack — 180 lbs. (82 kg)
• Exercises — triceps only
• Seat system — ratcheting pull-pin

Hoist CL-3103 Triceps Extension

• Price — $4,400.00
• Weight stack — 200 lbs. (91 kg)
• Exercises — triceps only
• Seat system — gas-spring assisted

Hoist HD-3100 Preacher Curl/Triceps

• Price — $3,960.00
• Weight stack — 190 lbs. (86 kg)
• Exercises — biceps and triceps
• Seat system — seven pad positions

Choose the RS-1103 if you train solo and want the assist pedal. Choose the CL-3103 if a tighter frame and a heavier stack matter more, or the HD-3100 if one machine has to earn its floor space twice. Compare all three against your room dimensions before you decide, and browse the full bicep and tricep machine range if a combo makes more sense.

Frequently Asked Questions

Can one person assemble the RS-1103?

No. Hoist's manual specifies two people for the build. You will also need a ratchet with 1/2", 9/16" and 3/4" sockets, an adjustable wrench, a rubber mallet, hex keys, a tape measure and a level.

Does Hoist publish a user weight limit for this machine?

No. Neither the product sheet, the live listing, the spec sheet nor the owner's manual states a maximum user weight for the RS-1103. Any figure you see quoted elsewhere is not from Hoist's documentation for this model.

Can the weight stack be upgraded?

Hoist lists a 5 lb stack upgrade on some models, including the HD-3100. No such option is published for the RS-1103, so treat the supplied stack as fixed unless Hoist Fitness confirms otherwise for your order.

Is shipping free on this machine?

Not on Hoist. Free shipping applies to selected brands only, and Hoist is not among them. Larger commercial pieces ship freight from our Tennessee base to all 50 states.

What is the return window?

Thirty days, with the equipment undamaged and back in its original packaging, subject to a restocking fee and return freight paid by you. Anything unboxed and used beyond testing is not eligible — see our shipping and returns terms for the full policy.

Is this the right machine for a light commercial room?

Yes, provided the floor can be drilled. Hoist's light commercial tier covers facilities that charge no membership dues and see no more than 50 users per day, which fits hotels, apartment clubhouses and training studios.
