Frequently asked questions
A:VO₂ max is the maximum rate of oxygen consumption during exercise, measured in ml/kg/min. It is the gold standard for cardiovascular fitness.
A:Heart rate zones (1–5) range from light activity to maximum effort. Zone 2 builds aerobic base; zones 4–5 improve speed and power.
A:The WHO recommends 500–1000 MET-minutes per week for adults, equivalent to 150–300 minutes of moderate-intensity exercise.
