The Biceps Curl and Triceps Extension machine features an angled arm pad designed to minimize shoulder movement, allowing for targeted emphasis on either the biceps or triceps. The curling/extension bar is adaptable, pivoting to accommodate different forearm lengths and axis of rotation alignment. The adjustable seat ensures ergonomic alignment of elbows with the machine. To enhance the user's experience, the machine is equipped with a built-in rep counter and top cap storage.
