How many calories does 100 sit ups burn

100 sit ups are a great way to start your day or finish it. They are also one of the best exercises for your abs. In this blog post, we will discuss how many calories 100 sit ups burn, the muscles used and how to increase the intensity. We will also provide an average time to complete 100 sit ups and close with a challenge! Are you ready? Let’s get started!

How many calories does 100 sit ups burn?

Due to the varied amount of data required, it is best to calculate the number by recording the number of sit ups performed in 1 minute.

Once you have this figure, we can calculate a 6 calorie burn per minute for a 100 lb individual working at an average pace ( light breathing )

Note:- add 1 calorie per minute per 10 lbs weight increase

divide the calories per minute calculated within 1 minute by the number of calories and record the result.

This result is the number of calories per sit, and from here, you can calculate the calories per 100 sit ups

Calories per minute / # of sit ups per minute = Calorie burn per sit up

100 sit ups = 100 x calorie burn per sit up

Factors that affect the number of sit up calories burnt.

The number of calories you burn from doing 100 sit ups depends on:

-Your weight

-you age

-The intensity of your 100 sit ups or how many sit ups you can perform a minute

-How long does it take you to complete 100 sit ups

The number of calories you burn from 100 sit ups also depends on the intensity of your 100 sit ups.

Aim for 100 repetitions in as little time as possible to maximise calorie burning.

I would suggest breaking the workout into chunks of 5 or 10 as part of a HIIT workout and aiming for perfect form or trying a different version each minute.

As you can see, the number of calories burned varies depending on the intensity level, weight and age. If you want to burn more calories, aim for 100 repetitions in as little time as possible at the highest intensity possible with the correct form.

What Muscles are used in performing a sit up

The primary muscle group worked during 100 sit-ups is the rectus abdominis. These long, flat muscles run down either side of your stomach and meet at your belly button in the middle. This is the “six-pack” muscle that many people try to target when they do sit ups.

The rectus abdominis is responsible for flexing the spine, which you do when you sit up.

In addition to the rectus abdominis, 100 sit-ups also work for the following muscle groups:

– External obliques: These are the muscles on the sides of your waist that you can see and feel when you put your hand on your hip.

– Internal obliques: These are the muscles beneath the external obliques.

Erector spinae: These muscles run along your spine from your neck to your lower back.

Hip flexors are a group of muscles that attach your thighs to your pelvis, and they help you lift your knees up towards your chest.

How to increase the intensity of a situp

You can do a few things to increase the intensity of 100 sit ups and make them more challenging.

-Add weight: Holding a weight in your hands or strapped to your chest will make 100 sit ups more challenging and help you build more muscle.

-Elevate your feet: Placing your feet on an elevated surface will make 100 sit ups more challenging and help you target your lower abs more.

-Do them slower: Taking longer to complete 100 sit ups will make them more challenging and help you build more endurance.

The average time required to perform 100 situps

Most people can complete 100 sit ups in two to three minutes. However, the time it takes to complete 100 sit ups will vary depending on your fitness level.

If you wish for a number to aim for we can look at the world record for the maximum number of situps in an hour – which was set in June 2020 by Jarrad Young and stands at 2.919 push-ups.

If you are new to exercise, start with 50 sit ups and build up to 100 over time.

Benefits of the Sit ups

Sit ups are a great exercise to add to your workout routine. They are relatively easy to do and don’t require any equipment.

In addition, sit ups help improve your core strength, making it easier to do other exercises like lifting weights or going for a run.

Finally, 100 sit-ups will help you burn a significant number of calories, which can help you reach your weight loss goals.

Common sit up mistakes

One common mistake people make when doing sit ups is arching their back. This can put stress on your spine and increase your risk of injury.

Another common mistake is using momentum to swing your body up instead of using your abdominal muscles to lift yourself up. This can also lead to injuries.

To avoid these mistakes, keep your back flat and use your abs to lift your body up.

If you are looking for a challenging workout that will help you burn calories and build muscle, 100 sit ups are a great option. Just be sure to practice good form to avoid injuries.


Q: What will happen if I perform too many sit ups?

A: While 100 sit ups is a great workout, you don’t want to overdo it. If you start to feel pain in your back or neck, stop and rest.


Q: Can I do 100 sit ups every day?

A: Yes, 100 sit ups every day is a great way to improve your fitness level. However, if you are just starting out, you may want to do them every other day or every third day to give your body time to adjust.


Q: I can’t seem to get past 50 sit ups. What should I do?

A: If you can’t seem to get past 50 sit ups, try the grease the groove method, which gradually increases the number of sit ups you can do over time.

Start by doing 50 sit ups every day for a week. Then, increase the number by five every week until you reach 100.


Q: I’ve been doing 100 sit ups for a while, and I’m not seeing results. What am I doing wrong?

A: 100 sit ups are a great exercise, but it’s essential to mix up your routine. Try adding weight, changing the tempo, or doing 100 sit ups in intervals.

You should also make sure you eat a healthy diet and get enough rest. If you are still not seeing results, consult a personal trainer or your doctor.


Q: What if 100 Sit ups are easy?

A: Try adding weight or elevating your feet. This will make 100 sit ups more challenging and help you build more muscle.
