Primal Performance Series 125kg Pin-Select Dual - Bicep Curl/Tricep Extension

The Primal Performance Series Dual Bicep Curl and Tricep Extension is a commercial pin loaded arm machine that trains both sides of the upper arm on one frame, with a 125 kg weight stack. It needs just 1090 × 1060 mm of floor space and stands 1630 mm tall, so gyms get two dedicated arm stations in the footprint of one.

Combining curls and extensions on one machine frees up floor space on a crowded strength floor while still giving members a fixed, supported path for direct arm work. Changing between the two movements takes a quick adjustment, not a trip to another station.

Who it is for

• Commercial gyms that want dedicated arm training without adding two separate machines
• PT studios with limited floor space that still need a full selectorised line
• Strength and conditioning facilities running accessory work alongside barbell programs
• Clubs and hotels where members want simple, guided arm exercises

Key features

• Two exercises on one frame: seated bicep curls and tricep extensions
• 125 kg pin select stack for quick load changes between sets and users
• Gas sprung adjustments for smooth, fast setup changes
• All metal components built to cope with busy commercial floors
• Urethane injection moulded pads with double stitched covers
• Laser cut metal shroud that encloses the stack for user safety
• Electro powder coated matte black finish to match the rest of the Performance Series dual range

Muscles worked and training uses

The curl side trains elbow flexion and the extension side trains elbow extension, so one station covers the front and back of the upper arm with the torso braced.

• Primary: biceps brachii (curl) and triceps brachii (extension)
• Secondary: brachialis, brachioradialis and forearm flexors
• Supersets of curls and extensions without moving to another machine
• Arm hypertrophy blocks in the 10 to 15 rep range with quick drop sets
• Accessory work after pressing and pulling sessions

Specifications

Frequently asked questions

How much space does the dual bicep and tricep machine take up?

It measures 1090 mm long, 1060 mm wide and 1630 mm high. With about 600 mm of clear space on each side for getting in and out, plan for a zone of roughly 2.3 × 2.3 m.

What weight stack does it use?

It runs on a 125 kg pin select stack. Users set the load by moving the pin, so there are no plates to handle.

Will it fit under a normal ceiling?

Yes. The machine is 1630 mm tall and neither movement travels overhead, so a standard 2.4 m ceiling gives plenty of room.

What does the warranty cover?

Primal Strength rates it for full commercial use with 5 years on the frame, 3 years on parts, and 1 year on pads, cables, pulleys and wearables, plus 1 year labour.

Can you deliver and install it in Australia?

Yes. We ship Australia-wide from our Melbourne warehouse, and most metro deliveries arrive 1 to 7 business days after dispatch. It weighs 303 kg packed, so some regional addresses need a freight quote. Send us your details through the Ask about this machine form on this page for a delivery and installation quote.

Is it a good choice for a home gym?

Primal builds it for PT studios and commercial floors rather than homes. If you still want one at home, check access first: the crate is 1800 × 1140 × 590 mm and 303 kg, so it needs a clear path and ground floor or lift access.
