Exercise is vital for building muscle, improving heart health and boosting energy.
However, a recent study suggests some of these results can be achieved without needing to go to the gym.
This is according to scientists who have developed a new compound that could recreate some of the physical benefits of exercise, such as enhanced metabolism and improved muscle performance.
This could be used to create a supplement pill in the future, focusing more on helping those with weakness due to illnesses like heart disease and old age, rather than used to replace exercise.

Those whose muscles have been weakened due to cancer or muscle atrophy could also benefit, and it could counter the loss of muscle that weight loss drugs bring on.
The study's principal investigator Bahaa Elgendy said: "We cannot replace exercise. Exercise is important on all levels. But there are so many cases in which a substitute is needed."
While this could be available in the future, the pill will not be widely available anytime soon as it has only been successfully used in rodent cells so far.
The compound works by activating specialised proteins that are oestrogen-related receptors in the body.
Such proteins regulate the impact of exercise on our muscles. In the rodent tests, the compound increased a fatigue-resistant type of muscle fibre and the endurance of the rodents improved when running on a treadmill.
This comes as another weight loss drug could launch "at the very least within this decade".
Amycretin is the work of Wegovy developer Novo Nordisk and is a new development in the world of weight loss drugs.

GETTYAmycretin showed incredible results during trials. After 12 weeks of taking the drug, patients lost around 13.1 per cent of their weight, compared to 1.1 per cent using a placebo drug.
This is a much more dramatic result than those using Wegovy over a similar time frame, as they lost around six per cent of body weight.
The drug mimics the appetite-reducing gut hormone GLP-1 and amylin, meaning people are less likely to overeat.
