What Muscles Does A Side Plank Work


What Muscles Does A Side Plank Work: The core muscles are a vital component of the side plank. When you perform a side plank, you engage your rectus abdominis, which is responsible for the “six-pack” appearance, as well as the internal and external obliques, which run along the sides of your torso. These muscles work together to stabilize your spine and prevent your body from sagging, helping you maintain a straight line from head to heels. The transverse abdominis, often referred to as the body’s natural weightlifting belt, is a deep-lying muscle that wraps around the abdomen. 

It plays a critical role in maintaining proper posture during the side plank by stabilizing your spine and pelvis. Strengthening the transverse abdominis can lead to improved core stability and reduced risk of back pain. The side plank also recruits the gluteus medius and minimus, two muscles located in the buttocks. These muscles are responsible for hip abduction, or moving your leg away from your body’s centerline. In the side plank, they work hard to keep your hips elevated and in line with your body, preventing them from dropping toward the ground.

The hip adductors, situated on the inner thighs, assist in stabilizing your lower body during the side plank. They help maintain proper alignment and prevent your top leg from drifting forward, ensuring that your body remains in a strong and balanced position. Your shoulders also play a crucial role in maintaining proper form during the side plank. The deltoids, located in the shoulders, stabilize your upper body and prevent you from collapsing. This engagement of the shoulders not only builds upper body strength but also enhances shoulder stability and resilience.

What Muscles Does A Side Plank Work

What are side planks good for?

Side planks allow you to simultaneously work on endurance, strength, and stability. Side planks are full-body exercises that work the core, arms, and legs. Planks can also improve balance by requiring you to stabilize your body in an unstable position.

Core Strength: Side planks primarily target the core muscles, including the obliques and transverse abdominis. This helps in building a strong and stable core, which is essential for posture, balance, and overall functional fitness.

Improved Posture: Strengthening the core muscles with side planks can lead to better posture. A strong core provides the necessary support for your spine, reducing the risk of slouching or developing poor posture habits.

Reduced Risk of Back Pain: The engagement of the erector spinae muscles in side planks can contribute to lower back strength and support, potentially reducing the risk of back pain and discomfort.

Enhanced Balance and Stability: Side planks challenge your body’s stability and balance, which can be particularly beneficial for athletes and individuals involved in activities that require good balance, such as yoga or martial arts.

Are side planks better than regular planks?

When we shift from plank into side plank, we reduce our contact with the floor, making it more challenging to balance. The extra effort required to balance teaches us to engage deep stabilizing muscles around our spine, hips, and shoulders, a lesson which brings powerful benefits both on and off the mat.

Regular Planks

Core Emphasis: Regular planks primarily target the front abdominal muscles, including the rectus abdominis and transverse abdominis. They are highly effective at building overall core strength.

Stability and Endurance: Regular planks are excellent for developing core stability and endurance. Holding a traditional plank position for longer durations can help build muscular endurance and improve posture.

Ease of Execution: Planks are generally easier for beginners because they involve a more straightforward body position, making them accessible for those new to core exercises.

Side Planks

Oblique Emphasis: Side planks primarily target the oblique muscles, including the internal and external obliques. They are excellent for strengthening the sides of the torso and can help create a more sculpted waistline.

Hip and Shoulder Engagement: Side planks engage the hip muscles, including the gluteus medius and minimus, as well as the shoulder muscles. This makes them a valuable exercise for hip stability, shoulder stability, and upper body strength.

Balance and Stability: Side planks challenge your balance and stability more than regular planks because you are supporting your body on one arm or elbow, which can be useful for athletes and those seeking to improve balance.

Is a 2 minute side plank good?

“Focus on doing multiple sets of smaller amounts of time,” says L’Italien. As you progress, you can extend your plank for up to one or even two minutes, but don’t go beyond that. “Two minutes is often considered the maximum, and you don’t get much more benefit after that,” says L’Italien.

Personal Goals: If your goal is to improve core strength and endurance, then a 2-minute side plank can be a significant accomplishment. It demonstrates that you have developed a strong core and good muscular endurance.

Progression: If you’ve worked your way up to a 2-minute side plank through gradual progression and have maintained proper form, it’s an excellent milestone. It’s crucial to start with shorter durations and gradually increase the time to avoid overexertion or potential injury.

Fitness Level: The ability to hold a 2-minute side plank also depends on your overall fitness level and experience with core exercises. Beginners might find a 2-minute side plank extremely challenging, while advanced individuals may aim for longer durations.

Form and Technique: It’s essential to ensure that your form and technique are correct during the entire 2 minutes. Maintaining a straight line from head to heels, engaging the correct muscles, and avoiding any compensatory movements are crucial for safety and effectiveness.

Does side plank reduce side belly fat?

Many wonder if side planks can help to reduce belly fat. Yes, it can because it works up your abdominal muscles. The yoga pose might seem easy to ace, but when you try to hold the position, you will experience a mildly painful stretch around your abdomen.

Muscle Toning: Side planks primarily work the oblique muscles (external and internal obliques), which are located on the sides of your torso. Strengthening these muscles can create a more sculpted appearance and enhance the muscle definition in the “side belly” area.

Calorie Expenditure: While side planks are effective for core strength and stability, they are not particularly effective at burning a significant number of calories. To reduce body fat, including fat around the sides, you need to create a calorie deficit, which is best achieved through a combination of cardiovascular exercise (e.g., running, swimming, cycling) and a balanced, calorie-controlled diet.

Nutrition is Key: Weight loss and fat reduction are primarily influenced by diet. Reducing your overall caloric intake and maintaining a healthy, balanced diet is the most effective way to shed excess body fat, including the fat around your sides.

Combination of Exercises: To complement your efforts, it’s a good idea to combine core-strengthening exercises like side planks with full-body workouts and cardiovascular activities to increase calorie expenditure and promote overall fat loss.

Do side planks help to get a smaller waist?

Strengthening this area of the abdominal wall actually decreases the risk of back pain and makes for a stronger, more stable core. From an aesthetic perspective, side planks will tone your obliques, “whittling” your waist and helping you lose inches, if that is your goal.

Oblique Strengthening: Side planks specifically target the oblique muscles, which are located on the sides of your torso. Strengthening these muscles can enhance their definition and create a more toned and sculpted appearance in the waistline.

Improved Posture: Side planks promote better posture by engaging the muscles that support your spine. As your posture improves, your waistline may appear smaller and more streamlined.

Core Stability: Strong obliques contribute to better core stability, which can reduce the appearance of a “pooch” in the lower abdomen. Improved core stability also encourages you to stand taller and engage your core muscles, which can make your waistline look slimmer.

Enhanced Balance: Side planks challenge your balance and stability. As you become more stable, you may find that you stand and move more confidently, which can give the impression of a smaller waist.

Injury Prevention: A strong and stable core, including the obliques, can help prevent injuries related to the lower back and hips, which can indirectly affect the appearance of your waistline.

What happens if I do side planks everyday?

Side planks work the deep spinal stabilizing muscle quadratus lumborum . Keeping this muscle strong can help reduce your risk of a back injury. Strengthens your core without stressing your back. Unlike crunches and situps, side planks don’t put pressure on your lower back.

Positive Effects:

Improved Core Strength: Doing side planks daily can lead to increased core strength and endurance. Your oblique muscles, along with other core muscles, will become more resilient and defined.

Better Posture: Strengthening the core through side planks can help improve your posture, reducing the risk of slouching and promoting a more upright, confident stance.

Enhanced Stability: Daily side planks can boost your overall stability and balance, which can be especially beneficial for athletes and individuals involved in activities that require stability.

Potential Negative Effects:

Overuse Injuries: Performing side planks every day without adequate recovery can lead to overuse injuries, such as strain or inflammation in the obliques, shoulders, or wrists. It’s essential to listen to your body and allow for proper rest.

Muscle Imbalances: Focusing solely on one exercise can lead to muscle imbalances. While side planks target the obliques and core, it’s important to include a variety of exercises to ensure balanced muscle development.

Plateaus: If you don’t progressively increase the intensity or duration of your side planks, you may reach a plateau where you stop experiencing significant gains in core strength.

How many side planks a day?

How Many Sets Of Side Planks Should I Do? There is no correct number of sets to do side planks for. 2-3 sets is a good place to start, however even adding just 1 set to your workouts will help with core strength.

Frequency: Side planks can be included in your routine most days of the week, but daily side plank workouts might be excessive for some individuals, especially beginners. It’s typically recommended to have rest days to allow your muscles to recover. You could aim for 3 to 5 days a week, giving yourself a break on the other days.

Repetitions: The number of side planks you should do during a single workout session can vary. You might start with 2 to 4 sets of side planks on each side, with each set lasting around 20 to 60 seconds. As you progress and your core strength improves, you can increase the number of sets or the duration.

Variation: To avoid overuse and muscle imbalances, you can vary your core workouts. This could include doing different types of planks (front, side, forearm, straight-arm, etc.) as well as other core-strengthening exercises. A well-rounded core workout might include a variety of exercises rather than just side planks.

Progression: To challenge your muscles and continue seeing improvements, consider increasing the intensity or duration of your side planks gradually over time. For example, you can aim to hold a side plank for an additional 5-10 seconds each week or add repetitions.

How long is a good side plank?

You can rest your top arm on your hip or, to make the move more challenging, raise it towards the ceiling. If you are new to the side plank, try to hold form for 15 seconds, then change to the other side. Otherwise, hold for 30-60 seconds and add time as you become stronger.

Beginner Level: If you’re new to side planks or have limited core strength, you can start with shorter durations, such as 15-20 seconds per side. This allows you to focus on maintaining good form while gradually building endurance.

Intermediate Level: For those with some experience in core exercises and better core strength, aim for 30-45 seconds per side. This duration provides a good balance between building strength and maintaining form.

Advanced Level: Advanced individuals with a strong core can aim to hold a side plank for 60 seconds or longer. This level of duration challenges your endurance and can help with muscle development.

Progression: As you become more comfortable with the exercise and your core strength improves, you can gradually increase the duration by 5-10 seconds at a time. Over time, this will help you continually challenge your muscles.

Listening to Your Body: Pay close attention to your body’s signals. If you start to feel excessive fatigue, discomfort, or if your form begins to deteriorate during the side plank, it’s advisable to stop and rest. Proper form is more important than the duration of the plank.

What Muscles Does A Side Plank Work


The side plank primarily focuses on the core muscles, including the rectus abdominis, internal and external obliques, and the transverse abdominis. These muscles work together to maintain spinal and pelvic stability, aiding in the development of a strong and toned midsection. Strengthening the core not only contributes to improved aesthetics but also enhances overall functional fitness, providing a solid foundation for various activities.

The engagement of the gluteus medius and minimus, along with the hip adductors, promotes hip stability, prevents hip sagging, and reinforces the side plank’s effectiveness. These muscles are essential for maintaining proper body alignment and ensuring that the exercise delivers the desired results. Incorporating the side plank into your workout routine also targets the shoulder muscles, including the deltoids and scapular stabilizers, which are responsible for upper body stability and maintaining proper form. 

Strengthening these muscles can lead to enhanced shoulder stability and reduced risk of injury. The benefits of performing side planks extend beyond muscle engagement. This exercise also promotes balance, coordination, and endurance, making it an excellent addition to functional training. Whether you’re an athlete looking to improve your performance, an individual seeking a stronger core, or someone aiming to prevent back pain, the side plank is a versatile and accessible solution.
