Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Position feet shoulder-width apart, slightly in front of the Smith machine bar. Unrack and secure the bar across your upper back. Maintain a straight back, engaged core, and chest up. Bend at knees and hips, keeping knees aligned with toes, to lower until thighs are parallel to the floor. Press through heels to return to the starting position, fully extending legs without locking knees. Repeat.
Keep knees aligned with toes to prevent injury. Use a controlled tempo. Push through heels to target quads and glutes. Maintain a tight core. Adjust foot position for full range of motion. Avoid locking knees.
