Arm isolation machines don't get the spotlight that racks and presses do, but Body-Solid makes three dedicated biceps/triceps machines at three very different price points. In this Body-Solid biceps triceps machine comparison we're lining up the DBTC ProDual, the GCBT-STK Pro Select, and the GCBT380B CAM to help you figure out which tier actually fits your gym's budget and traffic.
These aren't three versions of the same machine — they're a genuine good/better/best ladder, each stepping up in adjustability, build, and price. Here's how they stack up.
GCBT380B CAM Biceps Triceps — Entry Tier
Price: $930 | Construction: 2" x 2" and 2" x 4" steel, plate-loaded, 1" weight post | Product Weight: 79 lbs. | Height: 41"
The GCBT380B CAM Biceps Triceps is the entry point into Body-Solid's biceps/triceps lineup. It's plate-loaded rather than selectorized, which keeps the price down significantly and the footprint small — at just 79 lbs. it's the lightest and most compact of the three by a wide margin. That makes it a strong fit for smaller studios or home gyms that want a dedicated arm station without committing floor space or budget to a full stack machine.
Best for: Budget-conscious buyers and space-constrained gyms that don't need a weight stack.
GCBT-STK Pro Select CAM Biceps Triceps — Mid Tier
Price: $2,215 | Weight Stack: 210 lbs. (310 lb. upgrade available) | Construction: 2" x 2" and 2" x 4" steel | Dimensions: 52" L x 36" W x 71" H, 395 lbs.
The GCBT-STK Pro Select CAM Biceps Triceps is the middle tier, and the jump from the GCBT380B is significant: it moves to a selectorized 210 lb. weight stack (upgradable to 310 lbs.) instead of plate loading, which speeds up transitions between users on a busy commercial floor. At 395 lbs. and a larger footprint, it's built as a permanent commercial-floor fixture rather than a space-saving option, backed by Body-Solid's Commercial/Lifetime warranty.
Best for: Commercial gyms that want selectorized convenience and stack-based progressive loading without stepping up to the premium ProDual tier.
DBTC ProDual Biceps and Triceps — Premium Tier
Price: $4,175 | Weight Stack: 210 lbs. (310 lb. option) | Dimensions: 53" W x 40" L x 62" H, 501 lbs. | Cables: 5.5mm dia., 2,500 lb.-rated aircraft cable
The DBTC ProDual Biceps and Triceps tops the lineup as Body-Solid's premium ProDual model, carrying the brand's Full Commercial Warranty and heavy-duty 2,500 lb.-rated aircraft cables built for high-volume commercial use. At 501 lbs., it's a substantially heavier, more robust machine than either the GCBT-STK or GCBT380B, reflecting a build quality intended for high-rep, high-traffic environments like clubs and training facilities rather than home use.
Best for: Commercial clubs and training facilities that want top-tier durability and are equipping a floor for heavy daily use.
