Doing 100 push ups a day will make most people better at push-ups within a few weeks: more reps, better form and more upper-body endurance. Whether it builds muscle depends on how hard those 100 reps are for you. If your max is 15, 100 a day is serious training. If your max is 50, it’s mostly easy reps that add fatigue without much growth. It burns fewer calories than people expect (roughly 15 to 50), and doing it every day without a plan can irritate wrists, elbows and shoulders.
This guide covers what happens week by week, whether 100 pushups a day is good for your starting level, what the research says about muscle growth, how many calories it burns, the injury risks, and a plan to get there if you can’t do 10 yet.
What Happens If You Do 100 Push Ups a Day?
Here’s what most people can expect, and why:
- Week 1: your chest, shoulders and triceps get sore, especially if you haven’t trained them recently. Most people split the 100 into many small sets. Form often slips on the last sets.
- Weeks 2 to 4: the soreness fades and your max reps climb quickly. Most of this early gain is your nervous system learning the movement, not new muscle. In a 4-week study of progressive push-up training, bench press strength rose significantly but muscle thickness didn’t change yet [1].
- After a month: you need fewer, bigger sets to reach 100. If the reps were hard for you, your chest and triceps may start to look fuller. If 100 was easy from the start, expect little visible change.
- After a year: people who stick with it are usually very good at push-ups and have strong, durable shoulders. People who never make the push-ups harder tend to plateau within a few months, because 100 easy reps stops being a challenge.
Is 100 Pushups a Day Good? It Depends on Your Max
The same 100 reps mean very different things depending on how many you can do in one set. Test your max with good form first, then use this table.
| Your max in one set | What 100 a day means for you | What to do |
|---|---|---|
| Under 10 | Too much volume; form will break down | Start with incline push-ups and a lower daily total (see the plan below) |
| 10 to 30 | Hard, effective training for strength and muscle | Split into sets, take some rest days, add pulling work |
| 30 to 50 | Moderate: builds endurance, limited growth | Use a harder variation for some sets, or do fewer but harder sets |
| Over 50 | Mostly easy reps; little new stimulus | Make push-ups harder (decline, deficit, weighted) rather than doing more |
Not sure how your number compares? The push-up standards by age show what’s normal, and here’s how many push-ups the average person can do.

Yes, if the reps are hard enough. Push-ups are a real muscle-building exercise. In an 8-week study, young men who did push-ups twice a week, adjusted to match a bench press at 40% of their max, gained as much chest and triceps thickness and bench press strength as a group that did the bench press [2]. More on that comparison in bench press vs push-ups.
What decides whether your 100 reps build muscle is effort, not the number:
- Light loads work, but only near failure. A meta-analysis of 21 studies found that light and heavy loads build similar muscle when sets are taken to failure, while heavy loads build more maximal strength [3]. A push-up is a light load for most trained people, so sets need to end close to failure to count.
- More hard sets mean more growth. Muscle gain rises with the number of weekly sets, up to a point [4]. Ten easy sets of 10 when your max is 50 don’t count as ten hard sets.
- Frequency helps, but daily isn’t needed. Training a muscle at least twice a week builds more than once a week. Whether three or more times is better still isn’t clear [5].
So 100 a day builds muscle when it’s hard for you. Once you can do 40 or 50 in a row, keep it working by making the push-up harder instead of adding reps: elevate your feet, slow the lowering to 3 seconds, pause at the bottom, or wear a weighted vest or backpack.
How Many Calories Do 100 Push Ups Burn?
Not many. The 2024 Adult Compendium of Physical Activities rates calisthenics such as push-ups at 3.8 METs for moderate effort and 7.5 METs for vigorous effort [6]. Doing 100 push-ups takes about 4 minutes of actual work, which gives these rough figures:
| Body weight | Moderate pace (3.8 METs) | Vigorous pace (7.5 METs) |
|---|---|---|
| 55 kg (121 lb) | about 15 calories | about 29 calories |
| 70 kg (154 lb) | about 19 calories | about 37 calories |
| 85 kg (187 lb) | about 23 calories | about 45 calories |
| 100 kg (220 lb) | about 27 calories | about 53 calories |
That’s about the same as a 5 to 10 minute walk. 100 push-ups a day is a strength habit, not a fat-loss tool. If your goal is a flatter stomach, the calorie deficit and daily steps matter far more.
Is It Bad to Do Push-Ups Every Day? The Risks
Push-ups every day are fine for most healthy people if the volume is sensible. Problems usually come from doing too many hard reps, with poor form, without rest. Watch for:
- Wrists: push-ups put your full weight through bent wrists. Use push-up handles or dumbbells to keep the wrist straight, or do them on your fists.
- Elbows: pain on the inside or outside of the elbow is a common overuse sign. Keep elbows at about 45 degrees from your body, not flared straight out.
- Front of the shoulder: a pinching or aching feeling at the front of the shoulder means you should cut volume and check your form.
- Push/pull imbalance: hundreds of pushing reps a week with no pulling can round your shoulders forward. Match your push-ups with rows, band pull-aparts or pull-ups.
Rule of thumb: muscle soreness that fades within a day or two is normal. Joint pain, pain that’s sharp, or pain that’s still there the next morning is a signal to stop and rest for a few days. See a physiotherapist if it keeps coming back. If you have a heart condition or high blood pressure, check with your doctor before starting a daily challenge.
How to Do 100 Push Ups a Day If You Can’t Do 10
Build up to it instead of forcing 100 bad reps on day one.
Step 1: pick the right variation
- Incline push-ups (hands on a bench, table or wall): the easiest version. The higher your hands, the easier it gets.
- Knee push-ups: a step up. Keep a straight line from knees to head.
- Full push-ups: move to these when you can do 15 to 20 clean reps of the easier version.
Step 2: follow a 4-week ramp
| Week | Daily total | How to split it | Rest days |
|---|---|---|---|
| 1 | 40 | 8 sets of 5, spread through the day | 2 |
| 2 | 60 | 6 sets of 10 | 2 |
| 3 | 80 | 8 sets of 10, or 4 sets of 20 | 1–2 |
| 4 | 100 | 10 sets of 10, moving to 5 sets of 20 | 1–2 |
Use whatever variation lets you finish each set with good form and a rep or two left in the tank. Spread the sets out: one set every hour or so is easier on your joints than all 100 in one go. If a week feels too hard, repeat it rather than moving on.
A Better Version of the 100 Push-Up Challenge
If your goal is muscle and strength rather than a streak, this usually works better than 100 easy reps every day:
- 4 to 5 sessions a week, not 7.
- 4 to 5 sets per session, each stopped 1 to 3 reps short of failure.
- A harder variation once you pass about 30 reps in a set.
- The same number of pulling sets (rows or pull-ups) to balance your shoulders.

Why Push-Up Capacity Matters for Your Health
There’s one good reason to care about your push-up number beyond your chest. In a study that followed 1,104 male firefighters for 10 years, men who could do more than 40 push-ups had a 96% lower rate of cardiovascular events than men who could do fewer than 10, after adjusting for age and BMI [7].
That doesn’t prove push-ups protect your heart. Fitter men simply tend to do more push-ups, and the study only included active men. But it does make push-up capacity a quick, free check on your overall fitness, and a 100-a-day habit is one way to move it up. Women’s standards differ: see how many push-ups a woman should be able to do.
Frequently Asked Questions
Is 100 pushups a day good?
For most beginners and intermediates, yes: it improves push-up strength, endurance and form within a few weeks. It builds muscle only if the reps are hard for you, so it works best if your max is between about 10 and 30. If you can already do 50 in a row, a harder variation will do more than extra reps.
What happens if you do 100 push ups a day for a month?
Expect soreness in the first week, then a quick rise in your max reps over weeks 2 to 4, mostly from your nervous system learning the movement. By the end of the month you’ll reach 100 in fewer, bigger sets. Visible muscle growth in a month is modest and depends on how hard the reps were for you.
Will 100 push ups a day build muscle?
It can. Push-ups build chest and triceps about as well as a bench press at a matched load. But light loads only build muscle when sets are taken close to failure. If 100 reps are easy, they add little growth. Make the push-ups harder with elevated feet, slower reps or extra weight to keep progressing.
How many calories do 100 push ups burn?
Roughly 15 to 50 calories, depending on your body weight and pace. 100 push-ups take about 4 minutes of work, and the Compendium of Physical Activities rates push-ups at 3.8 METs for moderate effort and 7.5 METs for vigorous effort. That’s about the same as a short walk, so it’s not a fat-loss tool.
Is it OK to do push-ups every day?
Yes, for most healthy people, if the volume is sensible and the form is good. Take a rest day if you have joint pain, sharp pain, or soreness that lasts into the next day. Balance your push-ups with pulling exercises such as rows to avoid rounded shoulders, and use handles if your wrists hurt.
What happens if you do 100 pushups a day for a year?
Most people who stick with it become very good at push-ups and build durable shoulders and good upper-body endurance. Progress usually stalls after a few months if the push-ups never get harder, because 100 easy reps stops being a challenge. Rotating harder variations and adding pulling work keeps a long streak productive and balanced.
