Factors That affect numbers of burnt calories during exercise:

We Can't say " If you ran 30 min. you will burn 300 calories or if you lifted for 10 min. you will burn 100 calories " . This is because there are many factors that determine and affect the number of calories you are burning during the exercise , and those factors are:





A- Physiological Factors: 


1- Age " middle aged tend to burn more calories than extremities because of muscle content " .
2- Sex " males are more likely to burn calories more than females " .
3- Height .
4- Muscle mass of the body " Important factor , the more muscle >> the more calories you burn " .
5- Total body weight .
6- Basal metabolic rate " BMR "
7- Genetics .


B- Personal variability:

 

1- Intensity and effort during the exercise .
2- Experience at the exercise  .
3- Baseline fitness level .


C- Workout factors :


1- Length of the workout " the longer workout >> more burnt calories " to certain limit . . 
2- Intensity of the workout .
3- The group of Muscle used in the workout " squats burn calories more than crunches " .
4- Weights " heavy weight >> more burnt calories and vice versa " .
5- Type of the Training " hard or just lifting " .
6- your rest period " the more rest , the less burnt calories " .


D- Other factors:


1- Disease the increase BMR " thyroid disease " .
2- Level of stress .
3- Sleep status : " The better and enough time of sleep the more calories you are going to burn during your workout " .
4- Cortisol level .

According to the previous factors , number of calories burnt during an exercise will vary from another person to another " up to 90% variation " .
and another word i'd like to say : Don't focus on the number of calories you are burning during your exercise , just do it regularly because many exercises have benefits for the body more than calorie burning like walking , stretching and even yoga .

How to calculate Body fat percentage in your body:

First of all we have to know the definition of body fat %:

Body fat percentage refers to the % of fat in the body .

so if your weight is 200 pounds and your body fat % is 15% , this means that the fat in your weighs 30 pounds , and your lean body weight " muscle , blood , bone ' is 170 pounds .
So ,


How to calculate Body fat percentage in your body:

Easiest Formula: 


Calculation of body fat percentage for men:


- You have to weigh your self in pounds " 1 kg equals 2.2 Pounds " .

- You have to measure your waist in inches " 1 inch equals 2.5 cm " .

Then Apply this formula:

* Multiply your total body weight by (1.082) Then add 94.42 to the result .
      ( Body weight x 1.082 ) + 94.42 = A

* Multiply your Waist by 4.15 .
      ( Waist measurement x 4.15 ) = B

* A - B = Lean body weight .

* Body fat weight = Total weight of the body - Lean body weight 

* And finally :
    Body fat % = Body fat weight multiplies by 100 and divide the result on your total body weight .

    Body fat % = ( body fat weight x 100 ) / total body weight .


Calculation of body fat percentage for Women:


A= " Total Body Weight x 0.732 " + 8.987

B= Measurement of the Wrist " full point " / 3.140

C= measurement of the Waist " at the umbilicus " x 0.157

D= Measurement of the hip x 0.249

E= Measurement of the forearm x 0.434

Lean body weight = A+B-C-D+E

Body fat weight = Total body weight - Lean body weight

And Finally 
Body fat % = " Fat weight x 100 " / the total body weight .



* Classification of body fat % according to sex :
