What % of your body weight do u ues in a push up?

Answer 1

You must determine your (own personal) center of gravity for example by lying on a sea-saw (or equal) and finding where it is balanced (mark above or below your navel). Hands and arms must be in push-up position for an accurate measurement. Find cg by trial and error. Consider that your entire weight acts at the cg forming a couple (or moment) equal to your weight times the distance from cg to toes (pivot). Your hands form an opposing couple (opposite direction) equal to unknown force F times the distance from hands to toes (pivot).

Weight x distance (cg to toes) = F x distance (hands to toes)

You can now solve for F.

F/W x 100 equals percent of weight that F represents and the % of your weight you must lift.

As a shortcut, do a push up (static) on a bathroom scale to obtain F and your total W..

Answer 2

interesting I'm thing about a bed of nailes if you spread the weight of your bodie around many nails then you dont get hurt due to the weight each nail holds.

your hands and feet in a push spread you bodie weight between then.

also if you lift a wheel barrow to move it as normal you do not lift th whole thing do you, thus this means in a push up you are not lifting you whole bodie weight

Answer 3

Unless you cheat, you push up the whole body. The toes just act as a pivot.
