Bench press or push-ups? How to do both well

Push-ups and the bench press both build your chest. Three small trials compared them. In two of them, push-ups built bench-press strength about as well as the bench press itself.^[1][2] In the third, both groups got stronger.^[3] Two trials measured muscle size. The 8-week one found about the same chest growth with both.^[1] The 4-week one found no change in either group.^[3] The catch: those push-ups were hard. They were loaded, or done close to failure.

A push-up moves your body: hands on the floor, body straight, lower your chest and press back up. A bench press moves a weight: you lie on a bench and press a barbell or dumbbells up from your chest.

If your goal is a bigger bench press, train the bench press. In one trial, the push-up group got better at push-ups than the bench group did.^[3] Heavier loads also build more maximum strength.^[4] And the bench press is easy to load in small steps, such as 2.5 kg at a time. This is coaching practice, not a tested finding.

Why isn't this obvious? Gym lore files push-ups under "endurance" and the bench under "muscle". The trials don't back that split.^[1][2] But they were small and short, and they were run almost only in young men. The usual bench set-up cues (shoulder blades back, feet down, bar to the lower chest, safety pins set) come from coaches. Coaching practice. A few lab and model studies sit behind some of them. No injury trial does.

Why getting this right matters

Two things tend to go wrong. The first is easy push-ups. Someone who can do 30 does 3 sets of 10, calls it chest day, and wonders why nothing changes. In the trials below, push-ups built muscle and strength when the sets were hard.^[1][2]

The second is the bench press set-up. In US emergency-room records of weight-training injuries, the most common cause was a weight dropping on the person: 65.5% of cases.^[5] That count covers all lifts, not just the bench. It's still a good reason to set safety pins on the bench. Setting them takes ten seconds.

Getting it right also saves you from fake rules. Plenty of advice says a wide grip builds a wider chest, or that touching the bar to your chest wrecks your shoulders. No study below backs the first. None tested the second.

What the research says

A few terms first. 1RM (one-rep max) is the most weight you can lift once. Failure is the point where you can't do another rep with good form. RIR stands for "reps in reserve": how many more reps you could have done before you had to stop.

Hard push-ups did about as well as the bench press in small trials

"No significant difference" means about the same. It doesn't mean equal: 18 people is too few to spot a modest gap. The triceps grew in both groups, with no significant difference between them.^[1] The biceps grew only in the bench group.^[1]

Two more trials point the same way:

• Loaded push-ups. University students with advanced training experience trained for 5 weeks.^[2] One group did a 6-rep-max bench press. The other did push-ups made just as hard with an elastic band.^[2] A 6-rep max is the heaviest weight you can lift six times. Both groups raised their 1RM and 6-rep max by similar amounts, roughly 14% to 22%.^[2] This trial measured strength only.
• Push-ups that got harder as people improved. 23 moderately trained men trained 3 times a week for 4 weeks.^[3] One group did push-ups that moved to harder versions as they improved. The other did the bench press. Both groups raised their bench 1RM.^[3] The push-up group got better at push-ups than the bench group did.^[3] Neither group's muscle thickness changed measurably in 4 weeks.^[3]

Limited evidence. Three small trials, 4 to 8 weeks long, nearly all men. The push-ups in all three were hard: taken to failure, loaded with a band, or made harder as people improved.

Why light push-ups can work, if they're hard

A meta-analysis pools the results of many studies on the same question into one estimate. One meta-analysis of 21 studies compared light loads (60% of 1RM or less) with heavier ones.^[4] Every set went to failure, and every study ran at least 6 weeks.^[4] Light and heavy loads built about the same muscle. Heavier loads built more 1RM strength.^[4] Moderate evidence. The rep ranges and load article covers this in full.

The "to failure" part matters. In one 8-week trial, 25 untrained men trained on a leg machine with a light load (30% of 1RM).^[6] Taken to failure, the muscle grew 7.8%. The same light load stopped well short of failure grew 2.8%, which wasn't a clear change.^[6] Limited evidence: one small trial, one leg exercise.

So easy push-ups are probably not enough. If you can do 30, three sets of 10 leave about 20 reps in reserve on every set. Coaching practice. For how close to failure to go, see effort and reps in reserve.

Making push-ups harder or easier

One lab study compared 10 trained men and 10 trained women. It found that a push-up was a bigger challenge for the women than for the men.^[7] Limited evidence. Starting with knee or hands-raised push-ups is normal. Coaching practice.

How you set up changes the load. In a study of 23 adults (14 men, 9 women), push-ups with the feet raised pushed hardest into the floor.^[8] Push-ups with the hands raised, or from the knees, pushed least.^[8] Men and women showed the same pattern.^[8] Limited evidence, from one small study, though the direction surprises nobody.

The incline bench and the upper chest

In one 8-week trial, 47 untrained young men trained once a week.^[9] Groups did the flat bench, a 44° incline bench, or both, with the same number of sets.^[9] The incline group grew more at the top of the chest, just below the collarbone: about 6 mm more than the flat group.^[9] The other two chest spots they measured showed no difference.^[9] Strength gains, tested by pushing against a fixed bar, were about the same.^[9]

Limited evidence. One trial, in untrained men, training once a week, with the gap at one spot out of three. The incline group also started with a thicker upper chest than the flat group.^[9] So "one trial found more upper-chest growth" is fair. "You need the incline for your upper chest" is not.

Grip width: no training study yet

EMG (electromyography) uses sensors on the skin to measure how active a muscle is during a lift. It shows activity in one session. It doesn't show growth.

One study tested narrow, medium and wide grips in 28 men: 15 well trained and 13 with less experience.^[10] With a narrow grip, trained lifters handled about 7% less weight for 6 reps.^[10] Chest activity was about the same at all three widths.^[10] The wide grip worked the triceps less than the other two.^[10]

Limited evidence, from single sessions. Nobody has studied this well yet: we found no training study that tested whether grip width changes chest growth.

Full range: bar to the chest

Range of motion is how far a joint moves during a rep. In a 10-week trial, 50 trained men were split into four groups. Three trained the bench press: full reps (bar to the chest), two-thirds reps, or one-third reps. One stopped training.^[11] The full-range group gained the most strength. The shorter the rep, the smaller the gain.^[11] That trial measured strength and bar speed, not muscle size.

Limited evidence for the bench press itself. The wider research on full reps is covered in exercise selection and range of motion.

What protects the shoulder

The shoulder is a common problem area in lifters. A review found that up to 36% of documented lifting injuries and disorders were at the shoulder.^[12] Most of that data came from surveys of people looking back. The figure covers all lifting, not the bench alone.^[12] Limited evidence. It doesn't show that the bench press causes shoulder injuries.

One study built a computer model of the shoulder from 10 experienced lifters (9 men, 1 woman) pressing a light 16 kg bar.^[13] Two things lowered the estimated forces on the shoulder joint. One was gripping no wider than about 1.5 times shoulder width, measured across the bony tips of the shoulders. The other was pulling the shoulder blades back.^[13] The authors said this may lower injury risk.^[13] How far the elbows flared out mattered less than grip and shoulder-blade position.^[13]

Limited evidence. These are model estimates with a light bar. Nobody counted injuries.

Nobody has studied well whether leg drive or a big back arch helps or hurts a regular lifter.

How to do both well

How to bench press

These steps are coaching practice, not tested findings. Full range and the grip and shoulder-blade cues also have the limited support above.

1. Set the safety pins just below the height of your chest as you lie on the bench. They catch the bar if you can't press it. A spotter works too. Or use dumbbells you can lower to the floor at your sides.
2. Start light. The empty bar or light dumbbells, until every rep looks the same. Learning the lifts covers how.
3. Lie with your eyes under the bar.
4. Feet flat on the floor, backside on the bench. A small, natural arch in your lower back is fine.
5. Grip a little wider than your shoulders. Stay within about 1.5 times shoulder width.
6. Squeeze your shoulder blades back and down before you unrack the bar.
7. Lower the bar under control to your lower chest. Touch, then press back up. Let your elbows sit somewhere between tucked in and flared out.
8. Rack the bar with both hands when the set is done.

How to do a push-up

These steps are coaching practice, not tested findings.

1. Hands a little wider than your shoulders. Body in one straight line from head to heels.
2. Lower until your chest is near the floor. Press back up.
3. Pick a version hard enough that your sets end close to failure. Stop each set with only a few reps in reserve.
4. Climb the ladder. Start with hands on a bench or knees down. Then the floor, then feet raised. Then add load: a weight vest, a band, or a plate on your back.
5. Once you can do 20 to 30 floor push-ups, make them heavier. Raise your feet, add weight, or move to the bench press.

Which one to pick

• You want a bigger bench press: bench press.
• You want a bigger chest and train at home: push-ups, made hard.
• You have a gym and like both: bench press first, push-ups later in the session as a second chest exercise.

Worked examples

A 55 kg woman starting at home:

• Week 1: knee push-ups, 3 × 12, the last reps slow.
• Week 4: floor push-ups, 3 × 6, 5, 5.
• Week 10: floor push-ups, 3 × 15, 14, 13. Next step: feet on a low step.

A 90 kg man at the gym, bench press, 3 sets of 8:

• This week: 60 kg × 8, 8, 7.
• Next week: aim for 60 kg × 8, 8, 8.
• The week after: 62.5 kg, and start again from 8, 7, 7.

Both are progressive overload: do a bit more than last time. The numbers are examples, not a schedule. Write every set down so you know what "a bit more" means.

What's practical versus optimal. If you want a bigger bench, the bench press is the better tool. But push-ups you do three times a week beat a bench press you never get to.

Common mistakes

Easy push-ups. Push-ups feel like a warm-up, so people stop at a round number. Ten reps when you could do 30 is far from failure. Pick a harder version, or go closer to failure.

Stopping the bar short of the chest. It's tempting to load more and cut the rep short. In the trial above, full reps built more bench strength.^[11] Touch your chest, then press.

Benching alone with no safety pins. It's an easy step to skip when you're in a hurry. If the bar sinks on the last rep, there's nothing to catch it. Set the pins every time, or use dumbbells.

Going extra wide for a wider chest. It sounds logical. But in one study, chest activity was about the same at all three grip widths.^[10] And in the model study, wider grips raised the estimated shoulder load.^[13] Keep the grip moderate.

Treating the incline as required. One trial in untrained men found more growth at one upper-chest spot.^[9] That's a reason to try it if you like it, not a rule. Coaching practice: a moderate incline of about 30 to 45° is a common choice.

How Gymbers fits

Exercises in the Gymbers app come with a video you can watch before your first set. The app can add warm-up sets before your working sets. The log records the weight and reps for every set, and last session's numbers sit beside each set. You can log RIR next to each, so you know whether those push-ups were hard. For the bench, the app estimates your one-rep max from the sets you log, so you can follow it without testing a true max.
