Hoist ROC-IT RS-2102 Biceps Curl
SKU: RS-2102
Product Overview
The HOIST RS-2102 Biceps Curl applies ROX™ technology to the classic curl movement — the rocking seat forward lean increases the bicep stretch at full extension, then returns to optimal alignment during the curl peak contraction. The self-aligning handles adjust automatically to user arm lengths and the forward torso position engages core stabilization muscles as a secondary benefit of every set.
Key Features
- ROX™ technology: forward lean for increased biceps stretch
- Self-aligning handles adjusting to user arm dimensions
- Core activation through unsupported forward torso position
- Multiple grip width options for biceps head emphasis
- Silent Steel® weight stack for quiet operation
- Ratcheting adjustment for quick changes between users
