Jumping jacks, a classic and simple exercise, have been a staple of fitness routines for decades. Star jumps, a close cousin of jumping jacks, are a well-known plyometric and HIIT (high-intensity interval training) exercise. Whether a beginner or an experienced athlete, incorporating jumping jacks into your exercise regimen can be a valuable addition to achieving your fitness goals. This dynamic full-body movement involves jumping in place while extending the arms and legs outwards, then inwards as you bring your arms and legs back together. It is considered a high-impact plyometric exercise incorporating cardiovascular and strength-building challenges. Despite its basic nature, jumping jacks offer many benefits for weight loss, overall health, and fitness.
Blast calories with a full body, fat-burning workout, no pricey gym membership or special gear required. Jumping jacks can be done anywhere without needing any equipment and are easy to learn, making them an affordable and accessible option for all fitness levels. Doing daily jumping jacks may also assist in weight loss when incorporated into a regular, daily workout routine.
Understanding Star Jumps and Jumping Jacks
Star Jumps are one of many compound bodyweight exercises that work muscles across the entire body. They are whole-body workouts, relatively simple to perform, require no equipment, and can be done almost anywhere. It is a squat version of Jumping Jacks. Instead of jumping from a standing position, Star Jumps are performed from a squat position from where an explosive jump takes you into the air. They get your heart racing and your blood pumping. Increasing your heart rate with regular star jumps benefits your aerobic capacity and strengthens your heart.
Muscles Worked During Jumping Jacks
Jumping jacks target muscles in your core, lower body, and upper body as you continue to hop in place and use extending arm and leg movements.
- Lower Body: The primary muscles engaged during jumping jacks include the quadriceps (front thigh muscles), hamstrings (back thigh muscles), glutes (buttocks), calves, and hip abductors/adductors (outer and inner hip muscles, respectively).
- Upper Body: As you raise your arms overhead, the deltoids (shoulder muscles) and trapezius (upper back muscles) are activated, along with the muscles of the chest (pectorals) and upper arms (biceps). As you lower your arms back down, you will target your lat muscles (below your shoulder blades). The deltoids are shoulder muscles that activate when you lift your arms up and out to the side when you do star jumps. The delts comprise three heads; anterior (front), posterior (rear), and medial (middle).
- Core: Jumping jacks also require stabilization of the core muscles, including the rectus abdominis, obliques, and transverse abdominis. The work of the core muscles is to stabilize your spine during star jumps.
With this comprehensive engagement of upper and lower body muscles, jumping jacks provide an excellent all-in-one workout, contributing to increased strength, endurance, muscle tone, and overall physical fitness.

Benefits of Incorporating Jumping Jacks into Your Routine
Incorporating jumping jacks into your fitness routine has many benefits, including improved heart health, coordination, balance, weight loss, and more. Getting a good cardio workout is as simple as moving your body, such as doing bodyweight exercises like squat jumps, box jumps, burpees, jumping ropes, and jumping jacks.
Full-Body Engagement
One of the key benefits of jumping jacks is that they’re a full-body exercise, meaning the move works the lower body, upper body, and core muscles. One of the biggest advantages of jumping jacks is that they engage multiple muscle groups throughout your body. The legs, glutes, core, shoulders, and arms are all activated during the exercise. This makes it a fantastic full-body workout that targets different areas simultaneously. As a result, jumping jacks can help tone and strengthen your muscles, leading to a more defined physique.
Cardiovascular Health Improvement
Since jumping jacks elevate your heart rate, they’re considered to be a form of cardiovascular exercise. This move works double-time and can improve strength, too. “Jumping jacks can specifically improve aerobic capacity, decrease resting heart rate and blood pressure, decrease risk of cardiovascular disease, improve metabolism, and help to maintain a healthy weight,”. Regularly engaging in high-intensity aerobic exercise helps strengthen the heart and lungs, enhancing their efficiency in delivering oxygen to the body. As a result, your endurance and stamina will improve, enabling you to perform other physical activities with greater ease, such as walking, stairs, gardening, etc. Aerobic exercises like jumping jacks contribute to cardiovascular health by increasing heart rate and improving overall cholesterol levels. Scientific evidence links regular aerobic exercise, including jumping jacks, to a lower risk of heart disease.
Power Development
Add power, also referred to as elastic strength, to the growing list of benefits of doing jumping jacks. “Elastic strength is the ability for muscles and tendons to absorb and release energy,”. “And more power translates into successfully performing various exercises and activities like box jumps, jump lunges or even running,”. Here’s how jumping jacks help build power: “Like most plyometric exercises, jumping jacks require an eccentric and concentric contraction of a muscle or muscle group at a fast rate,”. “Eccentric would be the slow lengthening of a muscle contraction - perfect example is the ‘lowering’ movement in a squat. Concentric is the opposite of that. Think of this as the ‘shortening’ of the muscle [such as] when you stand up from the bottom of a squat,”.
Scalability
Another perk of jumping jacks: You can turn the intensity up or down, depending on your needs. “By simply changing the tempo of the exercise - moving quickly or slowly through each rep - or jumping higher [or] incorporating more power, the intensity of the exercise will change,”. To make jumping jacks more challenging, she suggested grabbing light dumbbells in each hand, which will work the shoulder muscles. Or, you can use mini resistance bands around each ankles to target the outer glutes. On the other hand, if you need to scale the exercise back, modifying jumping jacks by stepping your feet in and out rather than jumping, but still moving the arms the same way. “This is helpful if you have knee, ankle, hip, or lower back pain or injuries, or if you’re new to exercise and starting slowly,”. Alternatively, she added, you can isolate one area of the body to decrease the intensity by either moving only the arms or only the legs.

Hip Muscle Strengthening
Performing this move regularly can help strengthen the hip muscles by working the hips in two directions: Abduction, when the legs move away from the body, and adduction, when the legs return to the starting position, squared under the hips. “These abductor and adductor muscles make up the outer hips and inner thighs and are integral to pelvic stability and lower back support,”. In short: Hip muscles play important roles throughout daily life, and jumping jacks can be a fun way to strengthen them. And bonus points, jumping jacks can help with ankle strength and shoulder mobility. Consistently performing jumping jacks has been shown to increase overall hip strength, muscle power, and athletic performance.
Bone Density Improvement
Maintaining healthy bone density is essential for managing and preventing diseases such as osteoporosis (a disease that weakens bone), especially as people age and bone density naturally decreases. Thankfully, jumping jacks can help with that. Here’s how: “Jumping jacks are considered a weight-bearing exercise as the feet make contact with the ground,”. “Weight-bearing exercises produce force and stimulate part of the bone, which helps with new bone growth.” The impact of jumping jacks, although low-impact, helps maintain bone density and joint health. Research indicates that weight-bearing exercises like jumping jacks play a role in preserving bone mass and promoting joint flexibility, which helps to prevent injury.
Accessibility and Convenience
One of the best things about jumping jacks is that they can be done virtually anywhere and require no special equipment. As a bodyweight exercise, jumping jacks require minimal space and no specialized equipment, making them accessible anywhere. This versatile exercise can easily be thrown into a bodyweight-only high-intensity interval training workout that you can do no matter where you are.
Weight Loss and Fat Burning
Jumping Jacks Kick Calories to the Curb. Jumping jacks are an efficient, full body workout that also add cardio bursts of intensity, increase the heart rate needed to accelerate weight loss. In order to shed pounds, calorie-killing cardio such as jumping jacks is required to burn fat calories. Jumping jacks are an effective tool for weight loss and fat burning because they elevate your heart rate, target muscle building, and boost your metabolism. Combined with a well-balanced diet, regular jumping jacks can contribute to a calorie deficit, resulting in gradual and sustainable weight loss. Jumping jacks may contribute to an effective weight loss routine by accelerating your heart rate and boosting your metabolic rate. Studies suggest that incorporating high-intensity exercises, such as jumping jacks, can contribute to fat loss and weight management.
Mood Enhancement
Physical activity, including jumping jacks, triggers the release of endorphins (i.e., dopamine), which are natural mood lifters. Regular exercise can help reduce stress, anxiety, and depression while promoting well-being. Jumping jacks' rhythmic and repetitive nature can be meditative and help clear the mind, providing mental relaxation and improving cognitive function. The rhythmic nature of jumping jacks, coupled with the release of endorphins during exercise, acts as a natural stress reliever. Research indicates that aerobic exercises, like jumping jacks, contribute to reduced cortisol levels, which can help mitigate stress.

Time-Efficient Workout
Jumping jacks offer an excellent solution as they can be incorporated into high-intensity interval training (HIIT) sessions, providing an efficient and effective workout in a short amount of time. Just a few minutes of jumping jacks can elevate your heart rate and provide the benefits of a longer workout.
Flexibility Improvement
Jumping jacks, with their dynamic range of motion, actively engage various muscle groups, promoting flexibility throughout the body. Studies have shown that incorporating dynamic exercises like jumping jacks can lead to increased joint flexibility and improved overall range of motion.
Stamina Enhancement
Implementing a cardio exercise like jumping jacks gradually can help build cardiovascular endurance, enhancing overall stamina. Scientific studies demonstrate a positive correlation between aerobic exercises like jumping jacks and increased endurance levels. Adding this exercise into your routine will improve your stamina and train your body to move oxygen and blood to your muscles more efficiently.
Plyometric Exercise
Jumping jacks function as a plyometric exercise, improving explosive power and muscle strength. Research supports the notion that plyometric jump training, which includes jumping jacks, can lead to enhanced athletic performance and help build strength. Plyometric exercises, including jumping jacks, involve both eccentric and concentric muscle contractions. Stretching the muscles as you jump into the star shape involves an eccentric contraction, and then shortening the muscles as you return to the starting position is a concentric movement.
Calorie Burning
The high-intensity nature of jumping jacks makes them a great way to ramp up your training and burn additional calories during exercise. Studies highlight the effectiveness of aerobic exercises like jumping jacks in burning calories and supporting weight management.
How to Perform Jumping Jacks Correctly
Performing a jumping jack is simple and requires no special equipment. Follow these step-by-step instructions to execute this effective full-body exercise correctly:
- Starting Position: Stand with your feet together and your arms relaxed by your sides.
- The First Jump: Jump up explosively, spreading your feet to the sides while raising your arms above your head. Your feet should be shoulder-width apart, and your arms extended straight overhead.
- Mid-Air Position: At the top of the jump, your body should resemble an "X" shape, with arms and legs forming the lines of the letter.
- The Landing: As you land, control the movement and ensure your feet touch the ground simultaneously. Bend your knees slightly to absorb the impact, aiming for a soft landing to reduce joint stress.
- The Second Jump Position: From the landing position, jump again and return your feet together while lowering your arms to the sides to complete one repetition. Perform a desired number of repetitions to complete one set. Beginners can start with 10 to 15 reps per set and gradually increase as they become more comfortable and proficient in the movement. It is okay to start slowly while you learn the exercise and increase your speed as you improve!
Safety Tips
Here are a few safety tips to keep in mind to prevent injuries and maintain good form:
- Keep the movement fluid and controlled to minimize the risk of injury.
- Engage your core muscles during the exercise to stabilize your body.
- Land on the balls of your feet to cushion the impact and maintain balance, ensuring you have a soft bend in your knees to reduce the impact on your joints.
- Maintain a consistent pace throughout your sets for an effective cardiovascular workout.
- Warm up before engaging in any physical activity, including jumping jacks, to prepare your body for exercise and prevent injuries.
- If you are new to this exercise or have any health concerns, it's always a good idea to consult a fitness professional or healthcare provider before starting a new workout routine.
Variations of Jumping Jacks
Variations of jumping jacks can add diversity to your workout routine, challenge your muscles differently, and cater to various fitness levels.
Basic Jumping Jacks
The classic jumping jack involves jumping with feet together and then jumping wide while simultaneously raising the arms overhead. Return to the starting position and repeat the movement for the desired repetitions.
Squat Jack
To increase the intensity, perform power jacks by adding a squat before each jump. As you lower into the squat, swing your arms down and then explode into the jumping jack motion. Squat jacks are a cardio movement that will better tone your thighs and your glutes better than star jumps.
Seal Jacks
Start with your feet together and your arms crossed in front of your chest. As you jump, open your legs and arms wide, resembling a seal clapping its flippers. Return to the starting position and repeat.
Rotational Jack
Add a twist to the traditional jumping jack by jumping and rotating 180 degrees in the air. Land facing the opposite direction and repeat the movement, alternating the direction of the rotation with each jump.
Low-Impact Jumping Jacks
Perform this low-impact variation by stepping out to the side with one foot and raising the opposite arm overhead, mimicking the motion of a regular jumping jack without jumping. Bring your arm and leg back to the center, then switch to your other leg and opposite arm. This alternative is perfect if you’re recovering from an injury, starting out on your fitness journey or if you suffer with any kind of knee pain. This alternative is a stepping exercise rather than a plyometric (jumping) exercise so they’re a great low impact move.
Weighted star jumps
Add some resistance to your star jump exercises by adding a pair of dumbbells or ankle weights. You can also make them less challenging by squatting less deeply. This allows you to make star jumps suitable for most advanced fitness enthusiasts, intermediates, and beginners.
Jumping Jacks and Calorie Burning
Jumping jacks are a great form of cardiovascular exercise, they get your heart racing and your blood pumping. The amount of calories you burn doing jumping jacks can vary based on how long or how fast do you them, as well as on personal factors that affect your metabolism. Jumping jacks might seem like a basic exercise, but they offer serious benefits, including boosting your cardiovascular system and toning your muscles.
The exact number of calories you burn will vary from person to person. According to MyFitnessPal, jumping jacks can burn about 8 calories per minute for a person weighing 120 pounds (lb) and up to 16 calories per minute for someone weighing 250 lb. Several factors determine the number of calories you burn when doing jumping jacks.
Factors Influencing Calorie Burn
- Intensity: If it’s calorie burning you’re after, you’ll want to up the intensity. You can do this in two ways: Perform a high number of jumping jacks at a slow pace or perform a low number of jumping jacks at a fast pace.
- Metabolism: Your metabolism also plays a role in how many calories you can burn doing jumping jacks. Several factors affect your metabolism, including:
- Height and weight: The larger the person, the more calories they burn, even at rest.
- Sex: In general, males burn more calories than females performing the same exercise at the same intensity because they usually have less body fat and more muscle.
- Age: The aging process can change a lot of things about your body’s response to exercise, including the number of calories you burn. Factors that can affect this include an increase in body fat and a decrease in muscle mass.
Calculating Calorie Burn
To determine the number of calories you can burn during physical activity, exercise physiologists, trainers, and physical therapists often use metabolic equivalents (METs) for accuracy. One MET is the energy it takes to sit quietly. While at rest, you can expect to burn approximately 1 calorie for every 2.2 lb of weight per hour.
Moderate activity usually comes in around 3 to 6 METs, while vigorous activities burn more than 6 METs. Jumping jacks can range between 8 and 14 METs, depending on intensity.
To determine how many calories you’ll burn per minute, you can follow these steps:
- Multiply the METs of an exercise by 3.5.
- Take that number and multiply it by your weight in kilograms.
- Divide that number by 200.
Your result will be the number of calories you’ll likely burn per minute. You can also plug this information into an online fitness calculator, like this one from MyFitnessPal.
Jumping Jacks for Weight Loss
Cardiovascular exercise is a crucial component of any weight loss program. You can use METs as a general rule of thumb for the number of calories burned per lb for weight loss. For example, if you weigh 150 lb and perform 5 minutes of moderate to vigorous intensity jumping jacks, you can expect to burn around 47 calories.
According to the Centers for Disease Control and Prevention, to lose 1 lb per week, you’ll need to burn about 3,500 more calories than you take in each week. In general, you can do this by taking in 500 fewer calories every day and increasing your physical activity.
To burn an extra 500 calories doing jumping jacks alone, you would need to kick up the intensity. Even then, you would still need to do a good number of jumping jacks.
It may be better to consider making jumping jacks part of a larger fitness routine by:
- Doing them as a cardio interval between strength training sets
- Doing several sets of 5 minutes over the course of a day
- Making them part of a cardio circuit
Do Jumping Jacks Burn Belly Fat?
Jumping jacks contribute to overall calorie burn, which can aid in reducing body fat, including belly fat. Research highlights the efficacy of aerobic exercises like jumping jacks in overall weight loss. This quick and easy full-body exercise targets multiple muscle groups, including the arms, legs, and core, making it an effective way to burn calories and reduce body fat, including belly fat. The rapid movements increase your heart rate, helping to build endurance and enhance overall stamina. It also releases endorphins, which can relieve stress and improve your mood.
Potential Disadvantages and Precautions
Though generally safe for most individuals, excessive or improper execution of jumping jacks can lead to joint strain. Understanding proper form and individual limitations is crucial. Possible risks or disadvantages of jumping jacks include:
- Joint Impact: Jumping jacks involve repeated impact on the joints, which may lead to increased stress on the knees, hips, and ankles, especially for people with pre-existing joint issues. Landing after a star jump involves high impact, especially if you are muscular and heavy or just overweight. If you have lower back foot, knee, ankle, or hip issues, star jumps may not be safe or comfortable. If your knees tend to roll in and out when you do squats, they may be even more unstable when you do star jumps, increasing injury risks. Anyone with knee issues like cartilage or ligament injuries should know that the impact of landing and the deep squat position could exacerbate the problems.
- Overuse Injuries: Performing excessive jumping jacks without proper rest and in combination with other movements may contribute to overuse injuries.
Important Considerations
- The foundation of each star jump is the squat that engages your lower body.
- Keeping your core engaged is how you maintain control of your upper body when doing star jumps. A relaxed core when you land in the squat position after the jump could be detrimental.
- This is the biggest mistake you could make - not stopping when you feel pain or discomfort while doing star jumps.
- Furthermore, if you have a pre-existing health condition, consult your physician before beginning any new exercise program. Even if you do an exercise with perfect form, previous injuries could surface again, and you might have to make minor adjustments to the exercise to make it safe for you.
Always consult with a healthcare professional before starting a new exercise routine. Pay attention to your body, modify exercises as needed, and prioritize your health safety by working with a personal trainer.
