Whether it's swimming, jogging, tennis or yoga, we all have a favourite exercise - and we'd rather stick to what we know. Researchers tracked the physical activity of more than 111,000 men and women in the US over 30+ years. The team writes in the journal that “these data support the notion that long-term engagement in multiple types of physical activity may help extend the lifespan”. Those who participated in a diverse range saw “additional health benefits independent of total physical activity levels”. The NHS recommends adults in England aim for 150 minutes of moderate intensity activity or 75 minutes of vigorous activity per week.
