Performance
- Resistance range: 22–440 lb, set with one twist
- Twenty resistance levels, dialled in with a simple twist knob and no tools. Start light on day one, then keep turning it up. One compact trainer stands in for a whole rack of bands and dumbbells.
- Rep counter: Every rep, counted for you
- The built-in LCD counts each rep in real time, so you can chase a number instead of losing track mid-set. Pick a target, beat it, and watch it climb session after session.
Build & materials
- Frame: Double-layer carbon steel
- High-density carbon steel with a reinforced triangular structure and heavy-duty rivets, so it holds its shape at full load, rep after rep. Compact at 16.7 × 6.4 in.
- Handles: Non-slip ergonomic grips
- Wear-resistant PU handles shaped for your hand, with a textured grip that stays put through the longest sets. Choose black, blue or red to match your gym.
Use & fit
- Muscles worked: Chest, arms, shoulders and forearms
- Press, pull and squeeze from the same frame and train your whole upper body with one tool, in a corner of the room instead of a corner of the gym.

Specification
Every detail, spelled out.
What it is actually made of and how it is built, measured and described plainly, not marketing copy standing in for a spec sheet.
01 · Feature
Hydraulic power, safely housed
The cylinder and strength gauge sit inside a reinforced housing, so knocks stay off the working parts and the oil stays sealed in. A smooth micro-rebound brings the arms back under control, never snapping.
02 · Feature
A triangle that keeps every rep honest
The triangular frame locks each rep onto the same arc. No wobble and no wandering, just a stable, repeatable press from the first rep to the fiftieth.
03 · Feature
Folds away in seconds
One snap-lock at the base and it folds flat. Slide it under the bed, into a closet or into a gym bag, so a full upper-body session goes wherever you do.
04 · Resistance range
22–440 lb, set with one twist
Twenty resistance levels, dialled in with a simple twist knob and no tools. Start light on day one, then keep turning it up. One compact trainer stands in for a whole rack of bands and dumbbells.
