The S2AC Arm Curl Machine arms you with everything you need for solid performance—easy entry, smooth motion, and reliable support—so you can stay focused on your workout.
Seated curl with smooth resistance
The variable-resistance cam system guides your movement through a smooth arc, making every repetition feel controlled and consistent.
Adjustable seating for individual fit
With six seat positions available, users of different heights can dial in the right range, so your arm aligns naturally with the pivot.
Comfort that lasts
Thick DuraFirm padding cushions your arms and seat, reducing discomfort over long sessions.
Sturdy support for consistent use
Built from 2" x 3", 12-gauge steel with welded construction, this machine feels stable and dependable through every curl.
Safety-focused design
The fully shrouded weight stack keeps moving parts enclosed, keeping your workout space tidy and the machine easy to clean.
Full control with multi-grip handle
A revolving U-bar handle gives you options for different arm angles—whether you want high-peak contraction or deeper range.
Weight options for progression
Choose between the standard 160 lb stack or upgrade to 235 lb to support heavier users or higher-intensity workouts.
Designed for real-world gyms
With a weight of 380 lb and dimensions of roughly 41" L × 51" W × 57" H, it's a substantial, enduring fixture for any training area.
There’s no confusion here—just clean mechanics. You step in easily, choose your seat height, grip the U-bar, and start curling. The movement feels fluid and anchored with each rep. Switching grip positions offers flexibility without fiddly adjustments.
