The Truth About Exercise

In this short from BBC Horizon, Michael Mosley tries high-intensity interval training for the first time on an exercise bike. Sceptical that just a few minutes a week could rival hours of endurance exercise, he puts the claim to the test on himself. The clip offers a quick, science-led look at whether less can really mean more when it comes to fitness. For anyone curious about exercise and health, it is a brisk and intriguing watch.
