We should all aim for at least 150 minutes of moderate intensity exercise every week. 'Moderate intensity' is working at between 50% to 70% of your maximum heart rate. To work out your maximum heart rate (MHR), deduct your age from 220. To calculate your target heart rate (THR), multiply your MHR by 50% and 70%.
