Cable machines are versatile fitness equipment used in gyms for strength training. They consist of a frame with adjustable pulleys and cables, allowing users to perform a variety of exercises targeting different muscle groups. The adjustable weights provide resistance, making it suitable for both beginners and advanced athletes. These machines can be used for exercises like cable rows, tricep pushdowns, and cable chest flies. The design allows for a full range of motion, promoting better muscle engagement and reducing the risk of injury. Cable machines are popular for their ability to provide constant tension throughout the movement.
