Not Medical Advice

The information provided by StaminaCalculator.com, including all calculators, articles, guides, and results, is for educational and informational purposes only. It does not constitute medical advice, diagnosis, or treatment. Always seek the advice of a qualified healthcare provider with any questions you have regarding a medical condition, before undertaking any diet, exercise, or health programme.

Calculator Accuracy

Our calculators use validated scientific formulas from published research. However, all population-derived formulas carry inherent margins of error when applied to individuals. Results should be treated as estimates, not clinically precise measurements. Factors including unusual body proportions, medical conditions, medications, and ethnic background may affect accuracy.

Specific limitations by calculator:

• BMI: Does not distinguish between fat and muscle. May misclassify muscular individuals as overweight.
• Body Fat %: Circumference methods have ±2–4% error vs DEXA scanning.
• VO2 Max: Estimation methods have ±10–15% error vs laboratory maximal testing.
• Heart Rate Zones: The 220 − age formula has ±10–12 bpm variance.
• Calorie Calculator: TDEE estimates carry ±10–15% individual metabolic variation.

Do Not Use for Diagnosis

Results from our calculators must not be used to self-diagnose any medical condition, including but not limited to: obesity, cardiovascular disease, diabetes, eating disorders, or malnutrition. If our results suggest you may be outside healthy ranges, please consult a qualified physician or registered dietitian for professional evaluation.

Exercise Safety

Before beginning any new exercise programme, particularly high-intensity exercise, consult a physician — especially if you have a history of cardiovascular disease, hypertension, diabetes, musculoskeletal injury, or other chronic conditions. Exercise carries inherent risks. StaminaCalculator.com accepts no liability for injury or adverse events arising from use of our tools.
