A functional trainer is a versatile piece of gym equipment designed for functional strength training. It typically consists of two weight stacks and adjustable pulleys that allow for a wide range of movements in multiple planes of motion. Users can perform various exercises to mimic real-life movements and improve functional fitness, including pushing, pulling, lifting, and rotational movements. The adjustable cable height and attachments enable targeted muscle activation and rehabilitation exercises, making it suitable for users of all fitness levels. Functional trainers are valued for their ability to improve strength, stability, flexibility, and coordination, contributing to overall functional fitness and athletic performance.
