Smith single leg split squat

Stand in front of the smith machine with your feet shoulder-width apart. Place one foot behind you on a bench or step, with your toes pointing forward. Hold onto the smith machine bar for stability. Bend your front knee and lower your body down into a lunge position, keeping your back straight. Pause for a moment at the bottom, then push through your front heel to return to the starting position. Repeat for the desired number of repetitions, then switch legs.
