Medicine
Heart Rate Zone Calculator
Compute a target training heart rate using a Karvonen-style formula with resting heart rate, maximum heart rate estimated as 220 minus age, and a combined intensity factor (training zone Γ fitness level). Returns bpm.

Medicine
Basal Metabolic Rate Calculator
Estimate the calories your body burns at complete rest using the Mifflin-St Jeor equation, then multiply by an activity factor to get Total Daily Energy Expenditure. Use the resulting kcal/day as a baseline for diet planning.
