How to progress the exercise
This exercise can be made more challenging by using one leg instead of two. Also, Holding your arms crossed over your chest, as opposed to out by your sides, creates a greater stability challenge for your core.
Additional Information
Tip: To avoid arching your back during this exercise, focus on squeezing your glutes, as well as pulling in your abdominals, at the same time. The glutes and the abs contracting at the same time will keep your pelvis posteriorly rotated, which will keep your back flat throughout the movement.
