Fitness & Training Calculators
Training calculators for estimating the energy cost of exercise and the heaviest weight you could lift once. They use published MET values and lifting equations, and every page lists their limits.
How these calculators work
Every calculator in this group names its formula, shows a worked example and lists the sources behind its categories. The numbers are estimates based on the details you enter, so they work best as a starting point for a conversation with a doctor, dietitian or trainer rather than as a final answer.
