maintains physical fitness and overall health and wellness. It is performed for various reasons,
including strengthening muscles and the cardiovascular system, honing athletic skills, weight
loss or maintenance, and merely enjoyment. Frequent and regular physical exercise boosts
the immune system and helps prevent the "diseases of affluence" such as heart
disease, cardiovascular disease, Type 2 diabetes, and obesity.[1][2]

prevent depression, help to promote or maintain positive self-esteem, improve mental health
generally, and can augment an individual's sex appeal or body image, which has been found to
be linked with higher levels of self-esteem.[3]
Childhood obesity is a growing global concern,[4]

physical exercise may help decrease some of the effects of childhood and adult obesity. Health

proven benefits that it can provide.[5][6]
In the United Kingdom two to four hours of light activity are recommended during working
hours.[7]
This includes walking and standing.[7]
