As a runner, Pilates is one of my favorite ways to avoid getting injured before I reach the start line. The simple bodyweight exercises help me address imbalances in my body without putting additional strain on tired legs, plus they help strengthen my core and stabilize my hips.

I’ve already shared my favorite Pilates ab exercise for rebuilding my core postpartum, but one of my go-to leg exercises hits the quads, glutes, shins and deep core muscles — and you can do it while kneeling on your exercise mat.
