Turn your rack into a Smith Machine
The Polymax Smith Machine turns your Athéna or CS-1 rack into a guided machine, with no extra floor space. Two carriages mount on the front uprights and glide vertically on UHMW rollers. You attach your own barbell and get a guided bar path for squats, bench press, hip thrusts or overhead press.
What makes the difference
- Your own barbell. Keep the bar you like, with the knurling you prefer, and use specialty bars too.
- The upright stays usable. The carriages take little space: mounted on the front uprights, they still let you fit safeties and J-hooks inside or outside the rack.
- No extra floor space. Your rack becomes a Smith Machine, with no additional machine in the room.
- Affordable. Far cheaper than a full Smith Machine.
- Short handles included. For unilateral work: rows, presses, shrugs.
- 300 kg per side. Train heavy with confidence.
Compatibility
- 60x60 mm version: uprights with Ø 16 mm holes, Athéna racks.
- 75x75 mm version: uprights with Ø 25 mm holes, CS-1 racks.
- Rack 1,120 mm wide inside: use a barbell with a shaft longer than 132 cm, otherwise the sleeves may jam in the carriages.
Which barbell should I use?
Any Olympic barbell with a 28 to 30 mm shaft works, as well as specialty bars. To be sure of compatibility, we offer a dedicated bar, sold as a bundle with the Smith Machine.
