The Smith machine is a piece of weight training equipment designed to assist with various exercises. It consists of a barbell fixed within a vertical frame, allowing it to move only up and down. This design provides stability and safety, making it easier for users to perform exercises like squats, bench presses, and shoulder presses without a spotter. Many gym-goers appreciate the Smith machine for its ability to help beginners learn proper form and technique. Additionally, it allows for a controlled range of motion, which can reduce the risk of injury. However, some experienced lifters prefer free weights for a more natural movement pattern.
