Equipment

  • Suspension trainer

Setup

  1. Adjust the suspension trainer to mid-length and stand facing the anchor point.
  2. Grasp the handles with a neutral grip, elbows slightly bent, and center your weight on one foot.
  3. Lift the non-working leg off the floor, extending it slightly forward to clear the ground.

How to do it

  1. Inhale and lower your hips back and down in a controlled manner, keeping the working heel glued to the floor.
  2. Descend as deep as your mobility allows, using the handles for balance and minimal assistance.
  3. Exhale and drive through the mid-foot of the standing leg to return to the starting position.
  4. Perform all reps on one side before switching to the other to maintain consistent tension.

Form checklist

  • Keep the working knee aligned with your second and third toes.
  • Maintain an upright torso and avoid excessive rounding of the lower back.
  • Ensure the non-working leg remains elevated throughout the entire set.
  • Use your arms for balance only, avoiding the urge to pull yourself up with your upper body.

Pro tips

  • Focus on 'tri-pod foot' stability—distribute weight evenly between your heel, big toe, and pinky toe.
  • Slow down the eccentric (lowering) phase to 3 seconds to maximize muscle fiber recruitment and control.

Make it harder

  • Hold a pause at the bottom of the squat for 2 seconds to eliminate momentum.
  • Reduce the assistance by holding the straps with only two fingers on each hand.
