The Health-Index is calculated based on your activities during the last 7 days and enables you to check whether you have reached the minimum of the international recommendations for physical activity. All activities that last 10 minutes or less, as well as those with an intensity inferior to 3 will not be taken into consideration for the calculation of the Health-Index. Your load will thus be calculated by the product of the intensity and total duration of the activity. You should reach at least 150 minutes of physical activities with moderate intensity, or 75 minutes with vigorous intensity, or a mix of both, per week.
