How the Calculator Works
This calculator uses the Metabolic Equivalent Tasks (MET) method to find the calories burned from doing reverse crunches.
The MET represents the energy required to do a task. It is calculated conventionally with 3.5mL oxygen per kg of body weight of a person, which is multiplied by the number of minutes a person spends doing physical activity.
This is what gives you the MET value for that particular physical activity.
The calculation uses preset MET values for different physical activities such as doing reverse crunches to find the number of calories burned because of it.
Here is the formula for finding calories burned per minute:
Calories Burned Per Minute = (MET x 3.5 x Bodyweight(kg)) / 200
The MET stands for the Metabolic Equivalent Tasks. This term represents the amount of energy it takes to perform a physical task.
The value for MET increases as per the intensity of the task at hand. For example, lifting weights have a higher MET value than brisk walking.
Also, the relation between MET and the Resting Metabolic Rate (RMR) and the Active Metabolic Rate (AMR) are worth mentioning.
The Active Metabolic Rate is used to determine the number of calories burned while your body is in the active state. The RMR helps determine the number of calories that your body burns at rest.
The physical activities that have a MET value of 1 burn the same number of calories as your RMR. The activities that have a higher MET value such as 2, burn twice as many calories as your RMR.
MET Values Table
|Type of Activity||MET|
- How many calories does a person who weighs about 160 lbs (72.5 kg) burn from doing reverse crunches for an hour? The MET value for doing reverse crunches is 3.
- Calories Burned Per Minute = (MET x 3.5 x Bodyweight(kg)) / 200
- Calories Burned Per Minute = (3 x 3.5 x 72.5) / 200
- Calories Burned Per Minute = 3.8 calories
- Calories Burned in 60 Minutes = 3.8 calories x 60
- Calories Burned in 60 Minutes = 228.4 calories
What is a Reverse Crunch?
Reverse Crunch is a simple but effective core workout that anyone can do to get their body in great shape. The workout mainly targets your rectus abdominis which is an essential structure in your core and lower back.
This workout takes the strain off your neck and shoulders and helps you develop better posture without causing excessive post-workout soreness.
The workout is easy to set up and execute and requires no external help or equipment which makes it accessible for everyone.
How to Do a Reverse Crunch?
First of all, lie face-up on some soft and flat surfaces such that your legs make a 90-degree angle, and your feet are flat on the surface. Now take your thighs and using your core lift them so that they are in a vertical stance.
Now bring your knees as close to your face as you can while your back stays in contact with the surface while your hips and lower back are in the air.
Now return to your initial position by bringing your legs down. Make sure to put your hands flat on the floor while you do this exercise.
Benefits of Reverse Crunches
– Strengthens the Rectus Abdominis
The main purpose of the rectus abdominis is to flex your trunk and spine regions properly without straining these or neighboring muscles.
It is also responsible for your six-pack development. By performing reverse crunches regularly, you can make this muscle stronger and enjoy a more balanced and attractive body as well as posture.
– Feels Easy on the Back
Regular crunches can be a little intense and if done excessively they can even cause complications to your spine. On the other hand, reverse crunches are done while lying down in a natural state. Thus, these crunches do not put your spine through any extra stress.
– Helps Strengthen Core Muscles
This workout focuses on your rectus abdominis, external oblique, as well as on transverse abdominis which are integral for balanced movements of your body and posture in general.
Your core muscles are responsible for the normal functionality and movements of your entire body. Reverse crunches work on these muscles and make them stronger and more flexible. You feel more in control as well as energetic as a result of doing reverse crunches regularly.
– Helps Improve Posture
Improved posture is also a great effect of this exercise. By lying straight and moving your body in a controlled way, the pressure on your back and spine is reduced greatly.
This leads to better posture and overall health of your muscles and organs. Great posture eliminates stress on your neck, shoulders, as well as lower and upper back region.
– No Equipment Needed
You don’t need anything to perform this exercise except a flat surface and some comfortable clothes. The surface can be your carpet or even a small yoga mat. There is no special training required since everything is self-explanatory and simple.
Factors Affecting Calories Burned from Reverse Crunches
