High-Knee March With a Twist Start with your right foot extended back behind you and your hands together, reaching up and out (at about a 45-degree angle from your face). Keep your core tight and the weight on your left foot, with little to no weight on the right foot. Drive your right knee up and toward your chest as you bring your hands down and twist your upper body to the right. Re-extend your hands up and out while you tap your right foot back behind you. Tip: keep a soft bend in the knees. Keep repeating, and don't forget to switch sides. Image Source: POPSUGAR Photography / Kyle Hartman
