    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

    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.

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

    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...
    Try not. Do or do not. There is no try.

    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?

    When it comes to stomach area there are a few terms you need to know:
    1. Cortisol
    2. cyclic adenosine monophosphate (cAMP)


    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.

    Great start but a little off. The previous post didn't explain that 420J was only for pulling up. It would take 840.6 Joules to do a strict pullup because Potential Energy = Kinetic Energy. If you don't control your eccentric on your pulls you literally miss out on half the work. Here is more so people understand for future reference:

    Joules = Work = Mass × Ag × Distance
    1000 (Small) Calories = 1 (Large) Calorie
    1 Large Calorie is food calorie or 1kcal
    4181 Joules = 1 kcal (food calorie)

    4181 Joules per kcal / 840.6 Joules per rep = 4.97 or 5 reps to burn 1 kcal foodwise (1000 calories in chemistry teaching).

    So basically one strict pullup burns 1kcal/4.97reps = 0.2 calories. The previous calculation was 0.1kcal burned every rep but they didn't account for the work done when lowering yourself the other 2ft back down.

    You could say you burn less calories when you become more efficient at the exercise but also say you burn more calories by not pulling with flawless technique and wasting energy with contraction of other unnecessary muscle groups.

    So for simplicity sale we burn 0.2kcal (food calories) per pullup and it would take 100 pullups to burn 20 calories or 500 calories to burn 100 calories.

    Time doesn't matter in energy expenditure. Whether you do one set of 100 reps, five by 10, ten by five or 100 sets of one rep at a time you complete the exact same work against gravity regardless. The person that does a set of 20 reps will not burn any more than the person that does 5 sets of 4 reps.

    Put into perspective if you did a 100 pullups a day for 30 days challenge you would complete 3000 reps therefore burning 600 calories total. That means you would only lose 0.17 lbs if you did 100 pullups day for a month.

    THE POINT? Calories burned through muscular intensive exercise are completely insignificant. You can burn more in a single bike ride for 1-2 hours than a whole month of lifting weights/bodyweight. There are other factors like EPOC and afterburn and increases metabolism but that does not change the fact that lifting is an extremely insignificant part of weight loss. It would only contribute 20-50 calories to your daily defecit.

    If 50 calories makes or it breaks your maintenance, bulk or cut you definitely need to plan your diet better. Odds are you would just NEET away any extra calories if you don't eat a high enough surplus on a bulk. Don't get caught up in the caloric expenditure of lifting and just eat less or do more cardio if you want to lose weight.

    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.

    So, like, how to make that ^^^ NOT happen?

    Great start but a little off. The previous post didn't explain that 420J was only for pulling up. It would take 840.6 Joules to do a strict pullup because Potential Energy = Kinetic Energy. If you don't control your eccentric on your pulls you literally miss out on half the work. Here is more so people understand for future reference:

    Joules = Work = Mass × Ag × Distance
    1000 (Small) Calories = 1 (Large) Calorie
    1 Large Calorie is food calorie or 1kcal
    4181 Joules = 1 kcal (food calorie)

    4181 Joules per kcal / 840.6 Joules per rep = 4.97 or 5 reps to burn 1 kcal foodwise (1000 calories in chemistry teaching).

    So basically one strict pullup burns 1kcal/4.97reps = 0.2 calories. The previous calculation was 0.1kcal burned every rep but they didn't account for the work done when lowering yourself the other 2ft back down.

    You could say you burn less calories when you become more efficient at the exercise but also say you burn more calories by not pulling with flawless technique and wasting energy with contraction of other unnecessary muscle groups.

    So for simplicity sale we burn 0.2kcal (food calories) per pullup and it would take 100 pullups to burn 20 calories or 500 calories to burn 100 calories.

    Time doesn't matter in energy expenditure. Whether you do one set of 100 reps, five by 10, ten by five or 100 sets of one rep at a time you complete the exact same work against gravity regardless. The person that does a set of 20 reps will not burn any more than the person that does 5 sets of 4 reps.

    Put into perspective if you did a 100 pullups a day for 30 days challenge you would complete 3000 reps therefore burning 600 calories total. That means you would only lose 0.17 lbs if you did 100 pullups day for a month.

    THE POINT? Calories burned through muscular intensive exercise are completely insignificant. You can burn more in a single bike ride for 1-2 hours than a whole month of lifting weights/bodyweight. There are other factors like EPOC and afterburn and increases metabolism but that does not change the fact that lifting is an extremely insignificant part of weight loss. It would only contribute 20-50 calories to your daily defecit.

    If 50 calories makes or it breaks your maintenance, bulk or cut you definitely need to plan your diet better. Odds are you would just NEET away any extra calories if you don't eat a high enough surplus on a bulk. Don't get caught up in the caloric expenditure of lifting and just eat less or do more cardio if you want to lose weight.
    Normally I'd be all WTF for bringing back an old thread.
    But that was some good info. Rep'd.
