A cam lever is a mechanism that maintains consistent cable tension, ensuring smooth, even resistance throughout movement. It uses a specially designed cam that dynamically adjusts resistance as you pull, subtly shifting the leverage point to keep the cable taut and prevent slack or sudden jerks. This results in a fluid, controlled exercise experience with continuous muscle engagement, eliminating resistance drop-offs for more effective cable-based workouts.
