Scientists are working on a pill to help people who do no exercise. It could also increase the performance of those who do exercise. The scientists are from a biological studies institute in California. They say the pill could produce the same benefits to the body that it gets from running. It could make us healthier. It could give us more stamina, fat loss, a better mood, a healthier heart and a longer lifespan – all without exercising. The scientists said the pill helped to increase athletic performance in mice by 70 per cent. This could be good news for people who want to exercise more.

The scientists looked at how the body changes with exercise. A researcher said: "It's well known that people can improve their…endurance through training. The question for us was: How does endurance work? And…can we replace training with a drug?" He found a chemical that could copy the positive effects of exercise without needing to exercise. The chemical made the body burn fat instead of sugar. Burning fat instead of sugar means you can improve your stamina to the same level as someone who exercises, without the need to exercise.
