Body-Solid's ProDual line covers a lot of ground, and most buyers search by what a machine actually trains — a hip abductor adductor machine, a pec fly rear delt machine, a commercial biceps triceps machine — rather than by model code. This guide covers three ProDual machines that don't get discussed as often as some of Body-Solid's other commercial single-station lines: the DIOT, DPEC, and DBTC.
A note on naming: these three are the standard (non "-SF") ProDual models. If you've seen Body-Solid's separate Pro Dual Buyer's Guide covering the 7-machine "-SF" suffix lineup, that's a different set of models — the DIOT, DPEC, and DBTC below are not part of that -SF series, so don't assume specs or pricing carry over between the two lines.
DIOT: ProDual Inner Outer Thigh
Price: $4,710 (range $4,810.00 - $5,025.00) | Application/Use: Commercial | Type: Leg Machine | Weight Stack: 210 lb. (310 lb. option) | Dimensions: 76" L x 36" W x 62" H | Product Weight: 475 lbs. | Warranty: Body-Solid Full Commercial Warranty
The DIOT ProDual Inner Outer Thigh is a hip abductor adductor machine built as a dual-function station — one seat handles both the inner-thigh (adduction) and outer-thigh (abduction) movement patterns, rather than requiring two separate machines. Its 210 lb. weight stack comes standard, with a 310 lb. option available for facilities that need more resistance range.
Best for: Commercial facilities or serious home gyms that want dedicated hip abductor/adductor training in a single station.
DPEC: ProDual Pec Rear Delt
Price: $4,175 (range $4,275.00 - $4,490.00) | Application/Use: Commercial | Type: Chest Machine | Weight Stack: 210 lb. (310 lb. option) | Dimensions: 54" L x 38" W x 69" H | Product Weight: 502 lbs. | Cable: 5.5mm dia. 2,500 lb. rated aircraft cable
The DPEC ProDual Pec Rear Delt is the pec fly rear delt machine in the ProDual line, combining chest fly and rear deltoid training in one dual-function station. Like the DIOT, it ships with a 210 lb. stack and a 310 lb. upgrade path, and uses the same heavy-duty 5.5mm, 2,500 lb.-rated aircraft cable found across the ProDual family.
Best for: Facilities or home gyms that want combined chest and rear delt training without dedicating floor space to two separate machines.
DBTC: ProDual Biceps and Triceps
Price: $4,175 (range $4,275.00 - $4,490.00) | Application/Use: Commercial | Type: Arm Machine | Weight Stack: 210 lb. (310 lb. option) | Dimensions: 53" W x 40" L x 62" H | Product Weight: 501 lbs. | Warranty: Body-Solid Full Commercial Warranty | Cable: 5.5mm dia. 2,500 lb. rated aircraft cables
The DBTC ProDual Biceps and Triceps rounds out this group as a commercial single-station selectorized machine built specifically as a biceps triceps machine commercial applications rely on for high-volume arm training. Specs closely mirror the DPEC above — 210 lb. standard stack, 310 lb. option, and the same rated aircraft cable — with a slightly different frame footprint suited to the arm curl and pressdown movement pattern.
Best for: Commercial facilities or home gyms building out dedicated arm-training stations alongside other ProDual machines.
ProDual DIOT DPEC DBTC: How Do They Compare?
All three machines share the same core ProDual DNA — dual-function training, a 210 lb. standard weight stack with a 310 lb. option, and commercial-grade construction — but they target completely different muscle groups. The DIOT is legs (hip abductor/adductor), the DPEC is chest/rear delt, and the DBTC is arms (biceps/triceps). The DPEC and DBTC are priced identically at $4,175, while the DIOT runs slightly higher at $4,710, reflecting its larger frame footprint. Most buyers choose based on which muscle group is the current gap in their equipment lineup rather than comparing all three head-to-head.

Frequently Asked Questions
What is a hip abductor adductor machine?
A hip abductor adductor machine, like the DIOT ProDual Inner Outer Thigh, trains both the inner-thigh (adduction) and outer-thigh (abduction) muscle groups from a single seated station, rather than requiring two separate machines.
What does a pec fly rear delt machine do?
A pec fly rear delt machine, like the DPEC ProDual Pec Rear Delt, combines chest fly training with rear deltoid training in one dual-function station, using the same seat and cable system for both movement patterns.
What is a commercial biceps triceps machine?
A commercial biceps triceps machine, like the DBTC ProDual Biceps and Triceps, is a selectorized station built for high-volume arm training, combining bicep curl and tricep pressdown movements in one machine.
How do the ProDual DIOT, DPEC, and DBTC compare to each other?
They share the same dual-function design philosophy, a 210 lb. standard weight stack with a 310 lb. option, and commercial-grade construction, but each targets a different muscle group: DIOT for hips, DPEC for chest/rear delt, and DBTC for arms.
Are the DIOT, DPEC, and DBTC the same as Body-Solid's -SF ProDual machines?
No. These three are the standard ProDual models, separate from the 7-machine "-SF" suffix lineup covered in Body-Solid's other Pro Dual Buyer's Guide. Specs and pricing between the two lines shouldn't be assumed to match.
