How low should you go in a pushup? Lower your chest until it is about an inch off the floor, with your elbows bent to at least 90 degrees, then press all the way back up until your arms lock out. That full range of motion is what makes a rep count — anything shallower is a partial that trains only part of the movement.
What counts as a full range of motion pushup?
A full range of motion pushup travels between two clear endpoints. At the bottom, your chest lowers to roughly a fist's height off the floor — about one to two inches — while your elbows bend to 90 degrees or slightly past, so your upper arms are at least parallel to the ground. At the top, you press until your elbows fully straighten into a lockout and your shoulder blades spread apart. Skip either endpoint and you have done a partial, not a full rep.
Just as important is what your body does between those two points: it stays a straight line from the crown of your head to your heels. Hips that sag toward the floor or pike up toward the ceiling shorten the movement and shift load off the muscles that are supposed to be working. Brace your glutes and abs so your whole torso moves as one rigid plank, and keep your neck neutral rather than craning to look forward.
Here is the checklist for a rep that actually counts:
- Top: arms fully locked out, shoulder blades spread, body in a straight line.
- Bottom: chest within about an inch of the floor, elbows bent to 90 degrees or deeper.
- Throughout: head-to-heel plank held tight — no sagging hips, no piking, no bouncing off the floor.
Does your chest have to touch the floor?
No. Your chest does not have to touch the floor for a pushup to count — the working standard is that your chest comes within roughly an inch of the ground and your elbows bend to at least 90 degrees. Touching is simply a convenient cue that guarantees you reached depth; it is not a magic requirement, and for people with long arms or a deep chest it can even mean overshooting into a range their shoulders do not love.
Some standards are stricter on purpose. Military-style "chest to deck" tests and many fitness challenges require your chest, or a fist placed under it, to touch on every rep — precisely because a visible touch is hard to fake. If you are training to a specific test, follow its rule. For everyday strength work, the honest target is simpler: elbows to 90 or past, chest a thumb's width from the floor, then press. Lower under control rather than dropping and bouncing, because a bounce borrows momentum and steals the hardest, most valuable part of the rep — the bottom.
Are half pushups bad, or just a waste of time?
Half pushups are not completely worthless, but as your main training they are close to a waste of time. When you cut the rep short — usually stopping partway down and never reaching a deep elbow bend — you train strength mostly in the top portion of the movement, near lockout, where you are already strong. The bottom third, where your chest and shoulders are loaded at their longest and most stretched position, is where most people are weakest — and, going by current training research, likely where much of the growth stimulus comes from. Skip it and you build a strength curve with a hole in it, and you only ever load one part of the range.
Research on partial versus full range of motion training generally finds that training through a full range produces at least as much strength and muscle growth as partials — and, in some studies, more — with much of the benefit tied to loading muscles at longer lengths. Half-reps also quietly lie to you: they inflate your rep count, so the number on the page climbs while your real capacity in the hard range stalls. If you can grind out 40 shallow pushups but stall at 12 full ones, the 12 is your true number.
The fix is not to chase depth with ego. It is to own the range you can control with clean form, then extend it over time. If you cannot reach the floor with a good rep yet, regressing to a harder-to-cheat progression beats faking depth — slow negative pushups are one of the fastest ways to build the bottom-range strength that full reps demand.
When less depth is the smart call
Full range of motion means full range for your joints — not a one-inch-off-the-floor rule forced onto shoulders that cannot get there safely. If you feel a sharp pinch at the front of the shoulder near the bottom, that is a stop signal, not something to push through. Distinguish it from the normal burn of muscle fatigue: fatigue is a spreading ache in the chest, shoulders, and triceps; sharp, pointed joint pain is your cue to back off, reassess, and get it checked by a qualified professional if it keeps coming back.
A few ways to keep full range while respecting your shoulders:
- Elevate your hands. An incline pushup — hands on a bench, counter, or wall — lets you move through your full available range with far less strain, and you lower the surface as mobility improves.
- Mind your elbow angle. Flaring your elbows straight out to 90 degrees from your torso jams the shoulder at the bottom. Tucking them to roughly 45 degrees keeps depth achievable and the joint happier — see the 45-degree rule.
- Stop short of pain, not short of work. Go as deep as you can with zero sharp pain, treat that as your bottom, and earn more depth gradually instead of forcing it in one session.
The goal is the fullest honest range your body allows today — not an ego rep that trades your shoulders for one extra inch.
How to hit full depth on every rep
The hard part of full range of motion is not knowing the rule — it is that you cannot see your own depth mid-set, and it is remarkably easy to convince yourself you went lower than you did. Fatigue makes reps creep shallower rep by rep without you noticing. A few practical ways to keep yourself honest:
- Set a physical target. Place a fist, a rolled towel, or a foam roller under your sternum and touch it lightly each rep. When the target stops touching, the guesswork does too.
- Film from the side. One set recorded at hip height tells you instantly whether your elbows are actually reaching 90 degrees or quietly stopping at 120.
- Slow the descent. Lower for a two-count and pause for a beat at the bottom. Tempo removes the bounce and exposes the range you are truly training.
This is also where a tool can remove the friction entirely. Pushup Quest uses your phone's front camera and on-device pose detection to measure the depth and cadence of every rep, and it only counts reps that reach full range — a shallow rep simply does not register. Because the camera is the judge, you cannot cheat depth even when you are exhausted, so every rep in your streak is an honest one. It counts any variation, from wall and incline to knee, standard, and decline, and nothing — no video, no images — ever leaves your device.
Whatever variation you choose, the depth standard does not change:
| Variation | What "full depth" looks like |
|---|---|
| Wall | Chest nearly touches the wall, elbows bend past 90, then press back to a full lockout. |
| Incline (bench or counter) | Chest lowers to the edge of the surface, elbows to 90 or past. |
| Knee | Chest to about an inch off the floor, hips and shoulders dropping together as one line. |
| Standard | Chest within ~1 inch of the floor, elbows 90 or deeper, arms fully locked at the top. |
| Decline (feet raised) | Chest to ~1 inch off the floor with more load — same depth, higher difficulty. |
The bottom line: how low should you go in a pushup?
Go low enough that your elbows bend to at least 90 degrees and your chest hovers about an inch off the floor, then press all the way to a locked-out finish — every rep, from the first to the last. Your chest does not have to touch, but it does have to get close. Half-reps feel productive because the count climbs fast, yet they leave you weak exactly where strength matters most. Train the fullest range your shoulders allow, respect real joint pain when it shows up, and let honest, full-depth reps do the work.
