Sit-ups are a classic exercise used to strengthen the abdominal muscles and achieve a toned midsection.

Whether you want to get in shape, build core strength, or feel healthier, sit-ups can be a great addition to your fitness routine.

But how many sit ups should you do a day to see the results? With so much conflicting information, it can be hard to know where to start.

In this article, we’ll dive into the science behind sit-ups and a guide to help you determine how many sit-ups you should do each day to reach your fitness goals.

Calories Burned From Sit-Ups

To determine one’s rate at which one burns calories, it is important to note and consider the type of exercise one performs, their weight, and how invested they are in their exercise regime.

If we were to divide the number of calories a person were to burn according to their weight during a 30-minute exercise, it would be as follows:

  • 135 calories for a person that weighed 125 pounds
  • 167 calories for a person that weighed 155 pounds
  • 200 calories for a person that weighed 185 pounds

And it would continue so as the weight of the person increased.

Although many may achieve the desired result through 10-25 repetitions of sit-ups, it isn’t the case for everyone, as a person’s endurance level and strength differs from individual to individual.

Sit-ups may become a bit difficult during the 3rd and 4th sets, but you would have to persevere until you notice fatigue in your abdominal muscles to bring change.

A proper diet is necessary, so keep track of what’s happening inside your body during the exercise tenure.

Always ensure you are on stable, flat ground with your knees at a 90-degree angle, and position your hands either near the ears or below the chin before you start the exercise.

Muscles That Are Developed Through Sit-Ups

Sit-ups are primarily known for their ability to strengthen the abs muscles.

Specifically, they target the rectus abdominis muscles responsible for flexing the spine and creating the coveted six-pack look.

In addition to the rectus abdominis, sit-ups also engage the internal and external obliques, which help the rotation and lateral flexion of the spine.

The transverse abdominis, which acts as a deep stabilizer for the core, is also activated during sit-ups.

While sit-ups are a great way to develop core strength and tone your midsection.

It’s important to incorporate other exercises into your routine to ensure balanced muscle development and avoid overuse injuries.

How Many Sit-Ups A Day To Lose Belly Fat?

Many believe that only doing sit-ups will help one attain a slimmer waist and no belly fat. But that is not the case here.

Sit-ups are great for tightening the core, they strengthen and tone your rectus abdominous, transverse abdominous, and oblique abdominal muscles along with your neck muscles, and it is recommended to perform 3 sets of up to 15 – 25 repetitions 3 times a week.

To put it clearly, a maximum of 60 minutes of high-intensity cardiovascular activities such as running would help one burn belly fat.

It is also important to reduce one’s intake of processed foods, fast foods, and alcohol.

Nonetheless, just because sit-ups won’t help you get rid of your belly fat doesn’t mean that you should exclude them.

Instead, by doing sit-ups, you can strengthen your core which can provide you with the six-pack but will also relieve back pain, improve balance and increase flexibility.

How Many Sit-Ups A Day For A Six Pack?

Everyone asks, “What’s the best way to get a six-pack?” “Do sit-ups work?” “So, how many sit-ups should I do to get a six-pack?”

Sit-ups by themselves won’t provide the solution that you’re looking for. In the gym and outside the gym as well, you can get a firmer and more muscular midsection by keeping an exercise regime and focusing on the state of your body.

If your belly is toned and flat, 5 sets of 30 reps a day are more than enough, but if your abdomen has fat, start with 3 sets of 100 reps to help you achieve your stone-hard abs.

Keep on doing this exercise with other cardiovascular activities for a month, and you’ll see where your abs are at and you can adjust the number of sit-ups from there.

You need to make sure you handle what’s going on inside your body. A good nutrition plan also will assist you in burning calories.

Mistakes To Avoid

Sure, it’s important to learn how many sit-ups one must do, but it is equally important to consider the mistakes one commits when performing said exercise.

Sit Way Too High

Straight and bent-leg sit-ups cause equal pressure on the spine, which is bad.

According to research from the National Institute of Occupational Safety and Health, a healthy person’s lower back can only sustain 3,300 Newton’s of compression.

Pressure, any more than that, could increase the risk of injuries. So avoid putting pressure on the back and search for a better alternative, such as crunches.

Unnecessary Twists

It’s normal to experiment with the body. What’s not normal is increasing the risk of injury without consulting when using a variation in an exercise.

In this case, it’s when people think it’s good to twist when doing sit-ups, but it is not.

Your waist is already in motion when exercising, but adding a twist to it would only lead to risk regarding your spine, so stick to normal movement and save yourself from the pain.

Neck Jerks

This is a common mistake many people make when trying to lift their upper body off the ground.

When you jerk your neck, you strain your neck muscles unnecessarily and can even cause injury. Additionally, pulling on your neck with your hands can create tension in your shoulders and upper back.

To avoid jerking your neck during sit-ups, keep your neck relaxed and maintain a neutral spine position.

This means that your head should naturally align with your spine, and you should avoid tucking your chin into your chest or lifting your head too high.

One way to do this is to imagine having an apple or a tennis ball under your chin, which will help you maintain a neutral position.


There is no single answer to how many sit-ups one should do each day, as it depends on individual factors such as fitness level, endurance, and weight.

However, incorporating three sets of 15-20 reps into your workout routine is a good start. Sit-ups are a great way to strengthen muscles responsible for the spine and a toned midsection.

But remember, Sit-ups alone may not be enough to achieve your fitness goals, and it is crucial to include a variety of exercises that target different muscle groups and promote overall fitness and health.

Combining regular exercise with a balanced diet and healthy lifestyle habits can improve your physical and mental well-being and help you achieve your fitness goal.
