A smith machine is a weightlifting machine that consists of a barbell fixed to a vertical rail, allowing for guided up-and-down movements. It is commonly used for exercises such as squats, bench presses, and overhead presses.
The primary advantage of a smith machine is its inherent safety features. The fixed barbell ensures proper form and prevents the user from dropping the weight, making it suitable for beginners and individuals with mobility limitations. Additionally, the guided movement minimizes the risk of muscle imbalances and injuries.
