If you're shopping for the best bicep and tricep machine for a home gym, Body-Solid's arm-training lineup covers a wide range of budgets and setups, from plate-loaded CAM machines to fully stacked, commercial-grade cable stations. Isolating the biceps and triceps with dedicated machines lets you load specific angles that a barbell curl or dip alone can't reach, and it's a fast way to add volume to an arm day without waiting on a cable crossover. Below we break down six real Body-Solid machines — five built specifically for arms, plus one true shoulder/rear-delt option to round out the upper body — with actual pricing and specs so you can see what fits your space and budget.
Most of the machines below are pure biceps-and-triceps isolation stations. We've also included the DPEC ProDual Pec Rear Delt because rear-delt work pairs naturally with an arm day and it's the one machine in this group that actually trains the shoulder girdle — so if you came here looking for shoulder-specific equipment, that's your pick, while the rest of this guide is squarely about biceps and triceps.
GCBT380B CAM Biceps Triceps — Best Entry-Level Pick
Price: $930 | Type: CAM Arm Machine | Loading: Plate-loaded, 1" weight post | Frame: 2"x2" and 2"x4" steel | Weight: 79 lbs.
The GCBT380B is Body-Solid's CAM bicep tricep machine, and it's the most accessible way to get dedicated arm isolation without a weight stack to budget for. Because it's plate-loaded, you control resistance with standard Olympic plates, which keeps the machine's own footprint and weight down at 79 lbs. — easy to tuck into a home gym corner. The CAM design (a rotating pulley shaped to change resistance through the range of motion) is what separates this from a basic preacher curl bench: resistance builds where your biceps and triceps are actually strongest, rather than staying flat.
Best for: home gym owners who already have Olympic plates and want a compact, affordable dedicated arm station.
GCBT-STK Pro Select CAM Biceps Triceps
Price: $2,215 (range $2,315–$2,605) | Weight Stack: 210 lbs. (310 lb. upgrade available) | Frame: 2"x2" and 2"x4" steel | Dimensions: 52"L x 36"W x 71"H | Weight: 395 lbs.
Step up to the GCBT-STK Pro Select and you get the same CAM-driven biceps and triceps motion as the GCBT380B, but with a self-contained 210 lb. weight stack (upgradable to 310 lbs.) instead of loose plates. That's the appeal of a Pro Select bicep tricep machine like this one: no plate loading between sets, and a heavier ceiling for advanced lifters who've outgrown a plate-loaded station. At 395 lbs., it's built for a dedicated gym room or small commercial floor rather than a spare bedroom.
Best for: small commercial gyms or serious home gyms that want quick-change weight-stack convenience.
S2ACX Series 2 Arm Curl
Price: $2,795 (range $2,895–$3,125) | Weight Stack: 160 lbs. standard (235 lb. upgrade) | Weight: 380 lbs. | Dimensions: 41"L x 51"W x 57"H
The S2ACX is Body-Solid's Series 2 take on a dedicated arm curl station, built to commercial-grade standards with a stack-based system that's quick to adjust between users — a real advantage in a studio or small gym setting where several members rotate through the same station. The 160 lb. standard stack is lighter than some of the other machines here, but the 235 lb. upgrade option covers most serious lifters, and the Series 2 line is built for higher daily use than a home-only machine.
Best for: studios and small commercial facilities that need a dedicated arm curl station built for member turnover.
S2BTPX Series 2 Biceps and Triceps
Price: $3,140 (range $3,240–$3,475) | Weight Stack: 160 lbs. standard (235 lb. upgrade) | Weight: 400 lbs. | Dimensions: 52"x43"x84"
Where the S2ACX isolates the biceps, the S2BTPX covers both biceps and triceps in one commercial-grade Series 2 station, making it a more space-efficient choice if you only have room for one arm machine on the floor. It shares the same 160/235 lb. stack options as the rest of the Series 2 line, and its taller 84" footprint reflects a dual-motion design built to handle both curl and extension patterns from a single seat.
Best for: gyms that want one machine to cover both biceps and triceps instead of two separate stations.
DBTC ProDual Biceps and Triceps — Best for Serious Commercial Use
Price: $4,175 (range $4,275–$4,490) | Weight Stack: 210 lbs. (310 lb. option) | Weight: 501 lbs. | Dimensions: 53"W x 40"L x 62"H | Cables: 5.5mm dia., 2,500 lb. rated aircraft cable
The DBTC ProDual is the flagship of this lineup — a dual-function biceps and triceps machine built with 2,500 lb.-rated aircraft cables and a 501 lb. frame that's meant to take heavy daily use in a commercial club. The ProDual line is Body-Solid's top commercial tier, and the 210 lb. stack (with a 310 lb. option) gives it real headroom for advanced lifters. If budget isn't the deciding factor and you want the most durable bicep and tricep machine in Body-Solid's catalog, this is it.
Best for: commercial clubs and serious home gyms that want the most heavy-duty, highest-capacity option available.
DPEC ProDual Pec Rear Delt — The Shoulder Add-On
Price: $4,175 (range $4,275–$4,490) | Weight Stack: 210 lbs. (310 lb. option) | Weight: 502 lbs. | Dimensions: 54"L x 38"W x 69"H | Cables: 5.5mm dia., 2,500 lb. rated aircraft cable
The DPEC ProDual Pec Rear Delt is built for chest and shoulder work, not arms — but rear-delt flyes are a staple accessory movement on most arm days, which is why it's included here. Like the DBTC, it's built on Body-Solid's ProDual commercial platform with the same 210/310 lb. stack options and 2,500 lb. rated cables, so the two machines share a footprint and build quality if you're outfitting a facility with both.
Best for: gyms that already have the DBTC and want a matching rear-delt and pec station on the same commercial platform.

Frequently Asked Questions
What is the Body-Solid GCBT380 price?
The GCBT380B CAM Biceps Triceps machine is $930. It's plate-loaded, so that price doesn't include weight plates.
How does a Body-Solid CAM bicep tricep machine work?
CAM machines use a shaped pulley (the "cam") instead of a round one, so resistance changes through the range of motion to better match where your biceps and triceps are strongest, rather than staying constant like a straight cable pull.
Is a cable machine for biceps and triceps better than a preacher curl bench?
A preacher curl machine isolates one joint angle, while a cable or CAM-based machine like the ones above lets you work through a fuller range of motion and switch attachments. Neither is strictly "better" — it depends on whether you want single-angle isolation or more exercise variety from one station.
What's the difference between the Pro Select and Series 2 bicep tricep machines?
The GCBT-STK Pro Select uses a 210 lb. stack (310 lb. optional) in a 395 lb. frame, while the Series 2 S2ACX and S2BTPX use a 160 lb. standard stack (235 lb. optional) in heavier, more commercial-oriented frames built for higher daily use.
Which Body-Solid arm machine is best for a small commercial gym?
For a small commercial floor, the Series 2 S2ACX or S2BTPX are built for member turnover and daily use, while the DBTC ProDual is the step up if you want the highest-capacity, heaviest-duty option.
