Description

The equipment is a commercial-grade seated biceps curl machine, featuring a robust black steel frame with contrasting red adjustment points and movement arms. Design and Build The machine has a heavy-duty frame (often steel tubing) finished in black, designed for durability in a gym environment. Key components for user interaction, such as adjustment levers and the main cam/lever mechanism, are highlighted in bright red. It utilizes a pin-loaded weight stack system enclosed within the main upright structure for adjustable resistance. Ergonomics and Function The primary function is to provide an isolated and controlled exercise for the biceps muscle. Arm Pad: A large, angled black padded rest supports the user's upper arms and chest, ensuring the elbows are correctly positioned and preventing shoulder involvement or cheating with momentum. Seat: A black padded seat is typically adjustable vertically to accommodate users of different heights. Handles: The user grips handles attached to the red moving arm, which rotates around a fixed pivot point. Movement: The machine guides the user through a natural arc of movement, focusing the contraction purely on the biceps brachii.
