Why is it good to add strength training to your workout?

When you do exercise and weight training, you can lose or gain weight depending on your calorie intake.

Your Basal Metabolic Rate is an estimate of how many calories your body needs to maintain its current weight. It represents the amount of calories per day your body burns, regardless of exercise

These are the formulas for calculating BMR:

Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years )

Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in year )

To determine one's calories needs, you must multiply the BMR value by either 1.2, 1.375, 1.55, 1.725, or 1.9 depending on your level of physical activity. (1.2 for none, 1.9 for very high)

If your calorie intake is greater than this value, you will gain weight, if it is lower, you will lose weight.
