Jumping jacks are a classic full-body cardio exercise where you jump your feet out wide while raising your arms overhead, then return to standing. They raise your heart rate quickly while working the shoulders, hips, inner and outer thighs, and calves, making them a staple warm-up and conditioning move. Start with feet together and arms at your sides, then simultaneously jump your legs apart and sweep your arms up overhead, before reversing the motion in a steady rhythm. Land softly with a slight bend in your knees to absorb impact, and keep your core engaged so your movements stay controlled. Maintain an even, sustainable pace. Jumping jacks need no equipment and very little space, making them an easy way to warm the whole body, build cardiovascular endurance, and improve coordination between your upper and lower body.
