Scientists are working a new pill that could help people who do no exercise. It could also increase the performance those who do work and exercise. The scientists are the Salk Institute Biological Studies in California. They are developing a pill that could produce the same benefits the body that it gets running. Scientists are testing the pill mice. It could one day make people healthier. It could give them better stamina, fat loss, a better mood, a healthier heart and a longer lifespan – all doing any exercise. The scientists found that the pill also helped to increase athletic performance in mice 70 per cent. This could be good news people who want to run faster and farther.

The scientists looked what changes the body when people exercise harder and train or work longer. Researcher Dr Ronald Evans said: "It's well known that people can improve their aerobic endurance training. The question us was: How does endurance work? And…can we replace training a drug?" The researchers found a chemical that could copy the positive effects exercise the need exercising. The chemical made the body burn fat instead sugar. Another researcher, Weiwei Fan, said burning fat instead sugar means: "You can improve endurance to the [same] level as someone training, without all the physical effort."
