Set the Smith machine bar at knee height or slightly above, stand with feet shoulder-width apart, and grip the bar with an overhand grip. Brace your core and keep your back straight, then drive through your heels to lift the bar by extending your hips and knees. Pull the bar upward while keeping it close to your body, pause briefly at the top, then lower back down with control to the starting height.
Log your smith rack pull sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
