What is Push-Up?

A push-up is a bodyweight calisthenics exercise performed from a high plank position: hands under the shoulders, body in a straight line from head to heels. You lower your chest to just above the floor by bending the elbows, then press back up to full arm extension. Because it needs no equipment and scales easily by changing hand height or leverage, it is one of the most widely used tests of upper-body pushing strength and endurance, from military fitness tests to physical therapy programs.

How it works

A push-up works by using the pectoralis major to drive the arms across and down toward the torso (horizontal shoulder adduction), while the triceps brachii extend the elbow and the anterior deltoids assist the press. The core, glutes and quadriceps stay braced isometrically to keep the hips from sagging or piking, which is why a strict push-up trains far more than just the chest and arms. Changing the angle of your body relative to the floor changes how much of your bodyweight the upper body has to move — an incline push-up (hands elevated) is easier, a decline push-up (feet elevated) is harder.

How to apply it

• Incline push-up: Place your hands on a bench or step to reduce the load — the standard regression for beginners.
• Knee push-up: Perform from the knees instead of the toes to shorten the lever arm while keeping the same pressing pattern.
• Standard push-up: Full plank, hands roughly shoulder-width, chest to within an inch of the floor — the baseline strict rep.
• Decline push-up: Elevate the feet on a bench or box to shift more load onto the chest and shoulders.
• Weighted or single-arm push-up: Add a plate on the back or progress to archer/one-arm variations once 20+ strict standard reps feel easy.

Worked example

Say you can currently do 5 strict push-ups. Here's a simple 4-week volume progression to build toward 20 consecutive reps.

Add reps before adding sets, and only move to a harder variation (decline, weighted) once you can comfortably do 15-20 strict standard reps.

Push-up vs bench press

Push-ups and bench presses train the same pressing muscles; many lifters use push-up variations as an accessory or a travel/home-gym substitute for bench press.

Common misconceptions

• "Push-ups only train the chest." A strict push-up also heavily trains the triceps, anterior deltoids, and core, which is why sagging hips or a piked back are common form breakdowns.
• "Doing push-ups every day is the fastest way to build strength." Muscles need 48+ hours to recover between hard sets of the same movement; daily max-effort push-ups usually stall progress rather than speed it up.
• "Wider hand placement always works the chest more." Very wide hands mainly reduce range of motion and shift stress to the shoulders; a shoulder-width to slightly-wider grip trains the chest through its fullest range.

Push-Up FAQ

How many push-ups should I be able to do?

A reasonable beginner target is 10-15 consecutive strict push-ups; 20-40+ is a common intermediate-to-advanced benchmark used in many fitness tests.

What muscles do push-ups work?

Push-ups primarily work the pectoralis major, triceps brachii and anterior deltoids, with the core, serratus anterior and glutes acting as stabilizers that keep the body in a straight line.

Why do my push-ups hurt my shoulders?

Shoulder pain usually comes from flaring the elbows too wide or letting the hips sag; keeping elbows at roughly a 30-45 degree angle from the torso and bracing the core often fixes it.

Are push-ups as good as bench press?

Push-ups build the same pressing muscles and are excellent for endurance and core stability, but bench press allows more precise progressive overload since you can add small, exact weight increments.

How do I make push-ups harder without weights?

Elevate your feet (decline push-up), slow the lowering phase to 3-4 seconds, or move to archer or one-arm progressions once standard reps feel easy.
