Set up with a chair, bench, or step. You can find a good distance for the RLESS by sitting on the chair/bench and putting your front foot as far forward as it can reach while seated. This is where your front leg might feel best in the RLESS. You can put your back foot however is comfortable and stable and allows you to keep your hips square throughout the exercise. Lower your hips, sending your knee forward in line with your toe, then hold this bottom position for the allotted time.
