Scientists are working on new pill that could help people who do no exercise. It could also increase performance of those who do work out and exercise. scientists are from Salk Institute for Biological Studies in California. They are developing pill that could produce same benefits to body that it gets from running. Scientists are testing pill on mice. It could one day make people healthier. It could give them better stamina, fat loss, better mood, healthier heart and longer lifespan – all without doing any exercise. The scientists found that pill also helped to increase athletic performance in mice by 70 per cent. This could be good news for people who want to run faster and farther.

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