A leg press machine is a piece of gym equipment designed to strengthen the lower body, primarily targeting the quadriceps, hamstrings, and glutes. Users sit on a padded seat and push a weighted platform away using their feet, allowing for controlled movement and resistance. This machine is popular for its ability to isolate leg muscles without putting excessive strain on the back. Leg press machines come in various designs, including horizontal and 45-degree angles, catering to different preferences and fitness levels. They are often used in strength training routines and can be adjusted for weight to accommodate both beginners and advanced users.
