Growing up in many school activities we were made to do sit-ups and push-ups. In Navy Cadets we did pushups and situps whenever we exercised. I have also seen it included in many general fitness programs, including in a poster that appeared in our offices in the past couple of days.
Why are push-ups and sit-ups so common?
Is there any indication that these either:
- Easy for the general population to perform without significant risk of injury?
- Have a greater reward for effort compared to other exercise?
- Exercise a greater part of the body or areas of the body that need more attention?
