Setup
- Adjust the suspension trainer to mid-length and stand facing the anchor point.
- Grasp the handles with a neutral grip, elbows slightly bent, and center your weight on one foot.
- Lift the non-working leg off the floor, extending it slightly forward to clear the ground.
How to do it
- Inhale and lower your hips back and down in a controlled manner, keeping the working heel glued to the floor.
- Descend as deep as your mobility allows, using the handles for balance and minimal assistance.
- Exhale and drive through the mid-foot of the standing leg to return to the starting position.
- 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.
