1. ## About how many calories does a pull-up burn?

I'm 155.
I need an estimate of about how many calories a pull up burns?
thanks

2. none really it depends on how many you do and if you get your heart rate up. So if it does its very minimal. If your looking to burn calories your answer is cardio.

3. probably about 4 calories per pull up or you could just run for 15 minutes and burn about 160.

4. complicated question that seems simple on the surface!

Rather than worrying about this, I would calculate your BMR and go from there to determine what your excercise plan should be... trying to calculate every pull up is just going to give you a headache...

5. Is this for science class or something?

Assuming a range of motion of 2 feet from your chin to your fist, then:
m=155lb=70.3kg
g=9.8m/s^2
h=2ft=0.61m

work=mgh

Work = 70.3kg*9.8m/s^2*0.61m = 420N*m = 100calories = 0.1 kcal

Our bodies are very inefficient though. A lot of muscles need to get flexed in order to perform that .1 kcal of work. If you assume an efficiency of 10%, then you'd burn 1kcal doing that pull-up.

Is that what you were looking for?

6. Impressive physics Tiffany.

7. Tiffany..very nice physics calculations! You obviously paid attention.

Hi Tiffany, I have a little excess on my stomach area, i am starting to do 2 X 50 press ups & 2 X 50 pull ups within a space of around 10 minutes. What else could you suggest i do everyday / most days in order to lose this extra pounds?

That's funny though. I was actually going to say "about 1 cal" when I read the OP. I was just going to be guessing out of my ass though. 4 year old post, but still - rep for Tiffany.

15. They don't burn enough calories that is for sure.

When it comes to stomach area there are a few terms you need to know:
1. Cortisol

1. Cortisol is a natural hormone in our body that was used for our survival. In times of danger, this hormone would tell our body to take large amounts of stored energy (fat) and convert it into glucose in our blood stream. When we were in survival mode say running from a predator to survive, this hormone prepared our muscles by having sugar ready for them.
Cortisol was triggered by large events such as a lion chasing you, however today it can be activated by something as little as a text alert, or deadlines at work. If you've heard about chronic stress, Cortisol is a result of it.
The problem lies in the fact that say you've been super stressed all day, or super alert. This hormone has spent all day converting fat to blood sugar (why you have high blood sugar from stress) but at the end of the day you haven't essentially fought or flew. Your body starts the process of converting it back to stored energy (fat) but it settles down in the stomach area.

2. cyclic adenosine monophosphate (cAMP). this is a foreign term but really in simple terms it's a chemical sent to your brain to make you drowsy and tired. Imagine if you will a river that is flowing. the water is this chemical. hour by hour it sends these sleepy hormones, and there is a receptor to receive it. Caffeine has the same molecular structure as this chemical. when you consume it, it enters the receptors and tells essentially temporarily closes the doors so no more of these chemicals can enter. Now your body isn't getting sleepy.

This sends a hormone to the brain that something is wrong which the brain interprets it as a risk. it produces adrenaline and tells the body once again to convert fat to sugar. this is why when you drink a caffeinated drink, you fell perky, and some people feel jittery. because your body is pumping the blood full of sugar and adrenaline. But what happens when you come off that adrenaline high and the receptors start receiving this sleep chemical again? well all this time cAMP hasn't had anywhere to go so it's been chilling outside of the receptors waiting. once the doors open imagine a black Friday crowd rushing into 2 tiny doors. you guessed it. your brain gets bombarded with tiredness.
