The Body Fat percentage calculator will help you calculate the amount of fat stored in your body. It uses a method of measuring skin folds in seven different places on the body.

How to calculate your Maximum Heart Rate (HRMAX)? Which heart rate zones to choose for training and how to calculate the heart rate zones? At what heart rate is the best fat burning, and at what will we increase our efficiency and improve the condition? The calculator for maximum heart rate and heart rate zones can help answer these questions. You will calculate both your maximum and optimal heart rate and select the heart rate ranges for the appropriate training.
