Jumping jacks are a simple full-body exercise that mainly gets your heart rate up and works your legs, arms, core, and shoulders. They’re often used as a warm-up, cardio move, or quick conditioning exercise.

What they do

  • Raise your heart rate and improve cardiovascular fitness.
  • Activate multiple muscle groups at once, including quads, calves, glutes, hip flexors, abdominals, and deltoids.
  • Help improve coordination, rhythm, and balance because your arms and legs move together.
  • Can support strength and endurance, especially in the lower body.

Why people use them

Jumping jacks are popular because they’re fast, need no equipment, and can fit into warm-ups, home workouts, or HIIT routines.
