Set-up: Stand tall, brace through the core, pull your shoulder blades back and establish a neutral spine position. Place your weight onto your heels.
Movement: Step out to the side with your knee in line with toes. Do not allow your knee to pass forward over your toes. Land on your heels and not your toes. The trunk should remain stable and movement in the upper body should come from the hips. Think about hinging through your hips to lower your upper body, rather than flexing your spine.
Repetitions: Perform all prescribed reps on one side, then on the other. This counts as one set.
