When you start on a fitness regime, keeping count of the calories burnt is one of the most significant things to do, and also the most challenging job to do! The question is; why it is difficult for people to keep a track of their calorie count? The reason being, as everyone is of a different built and statistics, the calories burnt will vary in a different way depending upon the level of fitness. Some individuals burn more calories, but some burn less than others. In the majority of the cases, it is just a guess on the number of calories a person is burning. Keeping a track of your calorie burnout, will help you to make necessary changes in your dietary habits.
Your present weight, age, BMI & height are all taken into account while calculating your calories burnt. For e.g., a person with a height of 6.0 feet, weight 280 pounds would burn calories in a quick manner than someone who is say 5.3 feet tall and having the same weight. The calories you burn are governed by the amount of muscles you have in your body. Hence, the more muscles you have, the more amounts of calories you would burn. With the P90X workout program, you may aim to burn around 500 – 600 calories in the first hour.
I googled on P90X calorie calculator, though I am unsure about its accuracy. So, taking into account my statistics which are:
Age: 32 years
Body Weight: 264 pounds
Body Mass Index (BMI): 36%
Following were the figures according to the P90X calorie calculator:
1. Chest and Back – 745 calories burned
2. Plyometric – 1035 calories burned
3. Shoulders and Arms – 663 calories burned
4. Yoga X – 505 calories burned
5. Legs and Back – 972 calories burned
6. Kenpo X – 1010 calories burned
7. X Stretch – 316 calories burned
8. Core Synergistics – 858 calories burned
9. Chest, Shoulders, & Triceps – 732 calories burned
10. Back and Biceps – 631 calories burned
11. Cardio X – 1022 calories burned
12. Ab Ripper X – 454 calories burned
If you study the above data, you will observe that for me, majority of the exercises are in the range of 600 - 700 calories burned per hour. The cardio based workouts are above 1000 calories burned per hour. The workouts which are muscle based are in the 700 range. With passage of time, when you gain more muscles, your calories burnt out would in fact increase. Analyzing the data further, I can definitely say that the calorie calculator is greatly erroneous! The calculator doesn’t consider the muscle mass of a person.
Muscles burn out more calories than what fats could burn; meaning the more muscle you have, the more calories you would burn. The calorie calculator I had found on goggle does not consider this logic. It is ironic that a person weighing 265 pounds and not in a good shape would seem to burn more calories than a person who weighs 230 pounds and is in a good shape!!
