Smith Machine One Leg Squat Instructions

  1. Set up for the exercise by setting the bar in a smith machine to just below shoulder height and loading the weight you want to use. Position a flat bench or some type of raised platform around 2 to 3 feet behind the smith machine (your back will be to the bench).
  2. Stand under the bar with your feet about shoulder-width apart.
  3. Position the bar so that it is resting on the muscles on the top of your back, not on the back of your neck. The bar should feel comfortable. If it doesn't, try adding some padding to the bar.
  4. Now take your hands over the back and grip the bar with a wide grip for stability. You should now bend at the knees and straighten your back in preparation to take the weight off the rack. Keeping your back straight and eyes up, push up through the legs and take the weight off the rack.
  5. Place the top of your right foot on the bench behind you. You are now in the starting position.
  6. While maintaining your balance squat down through your hips by bending at the front knee.
  7. Keep your torso straight and head up. Don't allow your front knee to track out over your toes.
  8. Push yourself back to the starting position by using your heal to drive you.
  9. Repeat this movement for desired reps and then repeat with your left foot on the bench behind you.

Exercise Tips:

  1. Never allow your knees to track out over your toes during this movement. Doing so will place undue stress on the knee joints.
  2. This exercise requires a good deal of balance and is not recommended for those with balance issues. Begin by using a very light weight to first perfect the movement.
  3. Keep your head up and back straight throughout the exercise. Never allow your back to round.
