Description of Sit-up
Sit-up consists of exercise undertaken outside a building for the purpose of improving physical fitness. It contrasts with exercise undertaken inside a gym or health club for the same purpose. The activity may be undertaken in a park, in the wilderness, or other outdoor location.
It’s a natural antidepressant. Outdoor exercise can help ward off seasonal affective disorder (SAD), depression and anxiety because sunshine naturally increases serotonin, a hormone that affects your mood.
It challenges your body. When exercising on ever-changing outdoor terrain, your body is more challenged than when it is working out on a flat indoor surface.
