STS Preacher Curl Machine – Commercial Grade Biceps Curl Bench

Lock In Form. Isolate the Biceps. Build Serious Arms.

This ships freight for $250 due to its size and weight. 

The York STS Preacher Curl Machine is purpose-built for one thing — strict, focused biceps training.

By stabilizing the upper arm and eliminating momentum, preacher curls force the biceps to do the work — creating better contraction, cleaner reps, and more effective arm development.

Whether you're building size, strength, or simply improving arm training mechanics, this commercial-grade preacher curl bench delivers rock-solid stability and long-term durability.

No swing.
No cheating reps.
Just pure arm work.

Built with an adjustable seat pad, polished chrome bar holders, and heavy contour foam padding, it’s designed for repeated use in serious home gyms, training studios, and commercial facilities.
