People who are the least fit need to do 30-50 minutes more exercise a week than the fittest to get the same reduction in cardiovascular risk, according to research.
Researchers examined data from more than 17,000 British adults taking part in the UK Biobank study. They completed a cycle test to measure their baseline cardiorespiratory fitness (estimated VO2 max) and wore a fitness tracker for a week to record typical exercise levels.
