Single cable columns, also known as single cable machines, are versatile strength training devices found in many gyms. They feature an adjustable cable pulley system connected to a weight stack. The design allows for a wide range of exercises targeting different muscle groups, including chest, shoulders, arms, back, and legs. With the adjustable height of the pulley and interchangeable handles or attachments, users can perform various movements from different angles, making it ideal for functional training, strength building, and rehabilitation exercises.
