Editing Push-up (section)

===Other versions===
There are some less difficult versions, which reduce the effort by supporting some of the bodyweights in some way. One can move on to the standard push-up after progress is made.

"Wall" push-ups are performed by standing close to a wall and pushing away from the wall with the arms; one can increase the difficulty by moving one's feet further from the wall.

"Table" or "chair" push-ups are performed by pushing away from a table, chair, or other object. The lower the object, the more difficult the push-up. One should be sure that the object is securely stationary before attempting to push up from it.

"Three-phase" push-ups involve simply breaking a standard push-up into three components and doing each one slowly and deliberately. Participants usually start face down on the floor with hands outstretched either perpendicular or parallel to the body. The first phase involves the arms being brought palms down on a 90-degree angle at the elbows. The second phase involves the body being pushed into the up position. The third phase is returning to the starting position. This technique is commonly used after a large block of regular push-ups, as it poses less stress and requires less effort.

"Diamond" or "Triceps" push-ups are done by placing both palms on the ground and touching together both thumbs and pointer fingers. This technique requires stronger triceps muscles than regular push-ups because, at the bottom of the stroke, the forearm is nearly parallel to the ground and the elbow is almost completely flexed, resulting in a much higher mechanical load on the triceps. There is a special sub-set of the diamond push-up (so named for the diamond-shaped space between the hands when the thumb and forefinger of the left hand are placed on the floor up against the thumb and forefinger of the right hand.) The special version of this push-up is when the diamond is placed directly below the nose instead of the solar plexus. The nose must almost touch the floor in the center of the diamond. This special diamond push-up is done by the United States Marine Corps. The lips must come within 1 inch of the floor while keeping the neck in line with the straight spine to qualify as a valid push-up. This can be verified by placing a 1-inch foam disposable earplug on the floor in the center of the diamond and picking it up with the lips.

"Hollow-Body" push-ups are performed in the position gymnasts call the "hollow body". In the plank version of the hollow body, the shoulders are protracted into a pronounced curve in the upper back while the abdominal muscles are tightened and the legs are locked and squeezed together. This variation requires full-body tension to execute and results in greater integration of the hips, shoulders, and core.
