A must in circuit training, jumping jacks are a particularly dynamic exercise. Combining muscular and cardio strengthening, they allow you to burn a maximum number of calories. How can you achieve this and outdo yourself by trying a 30-day jumping jack challenge?
All about jumping jacks
Also known as star jumps or spread jumps, jumping jacks are as easy as they are fun. Their name is inspired by a toy puppet, Jack, whose arms and legs open by pulling strings. Performed from childhood as a warm-up or dynamic workout in the schoolyard, they are also effective for adults and are among the most explosive cardio exercises. Integrating a series of jumping jacks into a body weight-based session offers multiple benefits:
- Jumping helps to build bone strength over time.
- This fast-paced exercise increases the heart rate and makes you sweat in exactly the same way as when you jump rope: It helps to improve overall fitness and is also helpful in a weight-loss programme.
- Fun to do, this muscle-strengthening exercise involves the whole body and can be done by everyone, in a training circuit, alone, in sets or as a warm-up.
- In combination with more complex variations, they are an ideal basis for lively HIIT sessions.
How to perform jumping jacks properly
Jumping jacks involve a large number of joints and several muscle groups:
- The buttocks and leg muscles during jumps and landing: Calves, hamstrings, quadriceps, adductors, and so on.
- Abdominal muscles.
- Arm and shoulder muscles.
The classic jumping jack movement
To do this jumping exercise properly, break down the movement as follows:
- Stand with feet together and arms stretched out along the body.
- As you inhale, jump with your legs spread a little wider than shoulder-width and raise your arms at the sides to above your head, keeping them straight.
- When you land this first jump, have your legs apart and your arms in the air above your head.
- As you exhale, perform a second jump to return to your original position.
A few tips to make your jumping jacks a success
To perform your jumping jacks properly and avoid injury, here are a few tips:
- Even if you work indoors, wear trainers to support your ankles and cushion the impact of jumps on your joints.
- Keep your back straight and secure your abdominal muscles to maximize the benefits of exercise and protect your lower back.
- Keep your knees aligned during the exercise, without pointing them outwards or inwards.
- Propel yourself with your thighs and calves.
- Look straight ahead and avoid tensing your neck during arm movement by placing your shoulder blades well back.
- The more jumps you do, the more calories you burn! However, make sure you are consistent in your reps so that you don’t run out of breath.
- This exercise is ideal to practise to rhythmic music!

Once the challenge is over, you can set up a training circuit with jumping jacks and other exercises, such as push-ups or burpees, for example, and work in sections, on the principle of HIIT.
