A push-up is a moving plank. Your hands and feet stay planted while your chest lowers toward the floor and presses back up. Done right, it trains your chest, shoulders, triceps, and core in one move. Done wrong, it mostly strains your lower back and neck. The fix comes down to body position, hand placement, and keeping your hips and shoulders moving together.
How To Do Push Ups Right
Set up in a high plank. Hands slightly wider than your shoulders, fingers spread, wrists directly under your shoulders. Feet together or slightly apart for balance. Squeeze your glutes, brace your abs, and tuck your chin so your neck stays in line with your spine.
Now lower your body as one unit. Bend your elbows and let them track back at roughly a 45-degree angle from your torso — not flared straight out to the sides. Your chest comes down toward the floor, your hips drop at the same rate as your shoulders, and your whole body stays rigid. Stop when your chest is a few inches off the ground, or when you can no longer hold the plank without your hips sagging.
Press back up by pushing the floor away. Exhale on the way up. Lock your elbows at the top without hyperextending them. That is one rep.
The whole move lives or dies on one thing: your body moves as a single plank. If your hips sag, your lower back is doing the work your core should be doing. If your hips pike up, you’re offloading the work onto your shoulders. Both are signs you’ve lost the position.
Where Should Your Hands Go?
Hands slightly wider than shoulder width is the standard starting point. This width lets your elbows track back at that 45-degree angle instead of flaring out.
Hand placement changes which muscles get more work. A narrower grip shifts more load to the triceps. A wider grip puts more emphasis on the chest. Neither is “wrong” — they’re just different. For a general strength move, shoulder-width-to-slightly-wider is the most balanced.
What matters more than width is where your hands sit relative to your shoulders. They should be directly under or very slightly in front of your shoulders, not up by your ears. Hands too far forward turn the move into a shoulder strain.
Keep your wrists straight under your hands, not bent back sharply. If your wrists hurt, doing push-ups on fists or on push-up handles takes the wrist out of the extreme bend. Wrist pain is common in people new to the move and often settles as the joints adapt, but persistent pain is worth checking with a clinician.
What Are the Most Common Push-Up Mistakes?
The sagging hip is the number one error. When your core can’t hold the plank, your lower back arches and your hips drop toward the floor. This is where most push-up back pain comes from.
Flaring the elbows straight out to the sides is the second. It puts the shoulder in a vulnerable position and shifts stress to the front of the joint. Elbows back at around 45 degrees keeps the shoulder in a stronger position.
Other common mistakes:
- Head leading the way: Craning your neck to touch your nose to the floor first. Your chest should reach the floor before your face.
- Half reps: Barely bending the elbows. A shallow push-up builds less strength than a full range you can control.
- Holding your breath: Breathe in on the way down, out on the way up.
- Rushing: Speed hides lost form. Slow down until the position holds.
- Letting the hips pike up: Sticking your butt in the air shortens the range and takes the core out of the move.
If you can’t hold a rigid plank for the whole set, you’ve found your real limit. That’s not failure — it’s information. Drop to a variation you can do with clean form.
Can’t Do a Full Push-Up Yet? Start Here
Most people can’t do a full push-up on day one, and that’s normal. The move requires pressing strength plus core stability at the same time. Build both before you attempt full reps.
Incline push-ups are the best starting point. Put your hands on a sturdy bench, table, or counter. The higher the surface, the easier the move. This keeps the same body position and pressing pattern as a floor push-up but reduces how much of your body weight you’re lifting. As you get stronger, lower the surface.
Knee push-ups are another option. They reduce the load by shortening the lever. The catch: many people let their hips sag or pike when they switch to knees, so keep the same straight line from head to knees that you’d hold from head to feet.
Negative push-ups build strength fast. Start at the top, lower yourself slowly over several seconds with control, then reset by getting back to the top on your knees or by walking your hands back. The slow lowering phase builds strength even when you can’t press back up yet.
Pick one variation. Do clean reps. When you can do a set with perfect form and it feels manageable, move to a harder version. Progress comes from consistent practice, not from forcing full reps before you’re ready.
How Many Push-Ups Should You Do?
There’s no single correct number. It depends on your current strength and your goal.
For general strength, a common approach is a few sets of reps you can complete with good form, stopping a rep or two before your form breaks down. If you can do more than that comfortably, add reps or move to a harder variation. If you can’t complete the target with clean form, use an easier variation.
For building muscle, the total volume across a week matters more than any single set. Spreading push-ups across several days tends to work better than one big session. Give your muscles at least a day of recovery between hard sessions on the same muscles.
One clarification that surprises people: doing hundreds of push-ups a day does not automatically build a bigger chest. Past a certain point, extra reps build endurance more than size. If muscle growth is the goal, harder variations and added resistance do more than piling on reps.
How Do You Breathe and Protect Your Back?
Breathe in as you lower, breathe out as you press up. Don’t hold your breath — that spikes your blood pressure and makes the set harder.
Protecting your back comes down to the brace. Before you lower, tighten your abs like you’re about to be poked in the stomach, and squeeze your glutes. That combination locks your spine in a neutral position and stops the hips from sagging.
If your lower back hurts during push-ups, the cause is almost always a lost brace — your hips dropped and your back arched. Stop the set, reset your plank, and try again. If back pain continues even with clean form, or you have an existing back or shoulder injury, check with a doctor or physical therapist before continuing. Push-ups are not appropriate for everyone, and a clinician can tell you what to modify.
Shoulder health follows the same logic. Elbows flared out and hands too far forward are the usual culprits for shoulder discomfort. Fix the setup before you push through pain. Pain during a movement is a signal to change something, not to grit your teeth.
How Often Should You Practice?
Two to three sessions a week is a reasonable starting point for most people. That gives your muscles time to recover between sessions, which is when strength actually builds.
Consistency beats intensity. A few clean sets done regularly will take you further than an occasional max-out session. If you’re sore for days after a workout, you did too much — scale back.
As you get stronger, you can add frequency or difficulty. The key is to keep the form clean at every stage. A sloppy rep done for the sake of a number doesn’t build the strength you’re after, and it’s the fastest route to a tweaked back or shoulder.
Frequently Asked Questions
How wide should my hands be for push-ups?
Slightly wider than shoulder width is the standard balanced position. A narrower grip shifts more work to the triceps, while a wider grip emphasizes the chest.
Why do my hips sag during push-ups?
Your core can’t hold the plank position for the full set. Squeeze your glutes and brace your abs, or switch to an easier variation like an incline push-up until your core catches up.
Is it bad if my elbows flare out during push-ups?
Yes, flaring them straight out to the sides puts the shoulder in a vulnerable position. Keep your elbows tracking back at roughly a 45-degree angle from your torso.
How long does it take to do a full push-up?
It varies widely by starting strength and how consistently you practice. Some people get there in a few weeks using incline and negative push-ups, while others take several months. There is no fixed timeline.
