Jumping Jacks
Stand upright with your feet together and your arms relaxed by your sides. In one motion, jump your feet out to wider than shoulder-width while sweeping your arms up overhead. Immediately jump back to bring your feet together and your arms down to your sides, keeping a soft bend in your knees to absorb each landing. Maintain a steady, rhythmic pace and keep your core engaged throughout the timed set.
