A marathon might not be for everyone, however. According to experts, it doesn’t need to be.
If you aim for the NHS’ exercise recommendations, you should “reap the benefits”.
Professor Metin said: “Setting yourself a goal – such as training for a marathon – is a great way to stay motivated and follow through on your New Year health resolutions. But you don’t need to train for a marathon to reap the benefits.
“Aim for at least 150 minutes of moderate-intensity exercise every week or 75 minutes of vigorous exercise. More is usually better, but every bit counts.
“Even a brisk walk on your lunch break will steer you towards better heart and circulatory health.”
