Fitness and Health Calculator
What is Fitness and Health Calculator?
A Fitness and Health Calculator is a versatile online tool to instantly measure your key wellness statistics. With a single input, you can calculate your Body Mass Index (BMI), daily calorie requirements, Basal Metabolic Rate (BMR), and ideal heart rate zone for exercise.
These calculators help students, athletes, and health-conscious individuals understand their bodies and make informed choices about diet, activity, and lifestyle. Results are tailored to your age, gender, weight, height, and activity level.
Formula or Logic Behind Fitness and Health Calculator
The main formulas used are:
BMI = Weight (kg) / [Height (m)]²
BMR (Mifflin-St Jeor):
For Men: 10 × weight (kg) + 6.25 × height (cm) − 5 × age (y) + 5
For Women: 10 × weight (kg) + 6.25 × height (cm) − 5 × age (y) − 161
TDEE = BMR × Activity Factor (Activity Factors: 1.2 to 1.9 depending on lifestyle)
Target Heart Rate Zone = 50%-85% of (220 − Age)
These formulas are widely accepted in both academic and fitness settings for evaluating health metrics.
