Ever tried doing 100 push ups, 100 sit ups, and 100 squats in one session? Because of that, not spread across the week — in a single workout. It sounds like a dare. That said, or a punishment. Or something a cartoon character does to get buff That's the whole idea..
Turns out, it's a real training challenge that's been floating around gyms, forums, and living rooms for years. The "100 push ups 100 sit ups 100 squats" routine is exactly what it says on the tin. And people either love it, hate it, or limp for two days after trying it.
Here's the thing — this isn't some new fitness trend with a fancy name. It's brute-simple. But simple doesn't mean easy, and it doesn't mean smart for everyone That's the part that actually makes a difference..
What Is 100 Push Ups 100 Sit Ups 100 Squats
So what are we actually talking about? Day to day, the 100 push ups 100 sit ups 100 squats routine is a bodyweight workout where you complete those three movements for 100 reps each. That's 300 total reps of calisthenics, no equipment needed beyond your own body and maybe a floor you don't mind sweating on.
The official docs gloss over this. That's a mistake.
Some people do it as a circuit. Hit 100 push ups, then 100 sit ups, then 100 squats. But others break it into sets — 10 rounds of 10-10-10, for example. The goal is usually endurance, mental toughness, or just proving you can Less friction, more output..
Where The Idea Comes From
You might recognize the structure from pop culture. A certain manga character trains by doing exactly this every single day, plus a 10k run. That fictional routine planted the seed in a lot of real heads. But long before that, military PT, prison workouts, and old-school calisthenics fans were doing gross volumes of bodyweight reps Easy to understand, harder to ignore..
The appeal is obvious. You don't need a gym. You don't need a plan that costs money. You just need to show up and move.
Is It One Exercise Or Three
It's three exercises stacked into one session. Push ups hit the chest, shoulders, and triceps. That's why sit ups target the abdominal muscles (and hip flexors, whether you like it or not). That's why squats work the quads, glutes, and hamstrings. Together they cover a decent chunk of the body — upper, core, lower — without a single weight Easy to understand, harder to ignore..
But "cover" isn't the same as "train properly." We'll get into that.
Why It Matters / Why People Care
Why does this matter? Because most people overcomplicate fitness. They wait for the perfect program, the right shoes, the ideal meal plan. The 100 push ups 100 sit ups 100 squats idea cuts through all that. It says: here's a thing you can do today, in your socks, in 20 minutes if you're fit — or 60 if you're not.
And there's a psychological win. Finishing 300 reps of anything builds a kind of confidence that a fancy app can't give you. You did the dumb hard thing. You didn't quit.
But here's what most people miss: caring about this routine usually starts as a curiosity and turns into a lesson. In practice, a lesson about pacing, about form, about what your body will and won't forgive. I know it sounds simple — but it's easy to miss how humbling 100 squats can be when your legs are jelly from the first 40.
In practice, people use this challenge for a few reasons:
- As a baseline test of fitness
- As a daily habit for a month (bad idea, more below)
- As a quick sweat when traveling
- As a dare among friends
Real talk: the people who stick with any version of it aren't the ones chasing a six-pack. They're the ones who like checking boxes and feeling capable.
How It Works (or How to Do It)
The short version is: pick a structure, warm up, and go. But the details are where it either goes smoothly or goes sideways.
Warm Up First, Always
Don't roll out of bed and bang out 100 push ups. Here's the thing — get blood moving. Also, your shoulders and lower back will file a complaint. Spend 5–10 minutes easy: arm circles, leg swings, a light jog in place, some cat-cow stretches. The routine is already high-volume; cold muscles make it risky Small thing, real impact..
Choose A Rep Scheme
You don't have to do 100 of one move straight. Most beginners shouldn't. Common approaches:
- Straight sets — 100 push ups, rest, 100 sit ups, rest, 100 squats. Brutal on the targeted muscle group.
- Circuit style — 10 push ups, 10 sit ups, 10 squats. Repeat 10 times. Spreads fatigue, keeps heart rate up.
- Pyramid — 10, 20, 30, 40, then back down. Weird but breaks monotony.
- Grease the groove — 20 reps of each every hour across a day. Not a "workout" so much as a lifestyle annoyance.
For most people, the circuit style is the sane entry point. It's how you learn the workout isn't about one muscle — it's about managing total fatigue.
Form Over Speed
This is where the routine teaches you. Now, a push up with a sagging lower back isn't a push up. It's a back injury waiting politely. Same with sit ups yanked by the neck, or squats that look like you're folding in half Easy to understand, harder to ignore. Less friction, more output..
Worth pausing on this one.
- Push ups: tight core, hands under shoulders, full range down to near-floor.
- Sit ups: feet planted, use abs not momentum, don't pull the head.
- Squats: heels down, chest up, hips back like a chair, knees tracking toes.
Slow down if form breaks. The clock doesn't care, but your joints do.
Breathing And Rest
Breathe out on the effort (push up up, sit up up, squat up). If you're doing circuits, keep rest to 30–60 seconds. On the flip side, rest between sets only as needed. Here's the thing — if straight sets, a couple minutes is fine. Turns out, how you breathe changes how many reps you have left in the tank.
Track Your Time
First time, just finish. Also, second time, note the clock. On the flip side, that's the whole progression. On the flip side, third, try to beat it by a minute. No app required Less friction, more output..
Common Mistakes / What Most People Get Wrong
Honestly, this is the part most guides get wrong — they treat the challenge like it's a complete program. It isn't Small thing, real impact..
Thinking It Builds Real Strength
Doing 100 of anything builds endurance, not maximal strength. Worth adding: your muscles adapt to repetition, not load. If you want to bench heavy or sprint fast, this won't get you there alone. It's a piece, not the puzzle.
Doing It Daily
The manga character did it daily. Doing 100 push ups every day for a month is a fast track to elbow tendonitis and a grudge against floors. Real human bodies need recovery. Rest days aren't optional. Tendons, especially. They're the deal The details matter here. Still holds up..
Ignoring The Sit Up Problem
Sit ups get a bad rap in rehab circles for a reason. They load the spine and overuse hip flexors. If your lower back hurts during them, swap to crunches, leg raises, or planks. The "100" is arbitrary. Don't sacrifice your back for a number.
Terrible Squat Depth
Most people do half squats when tired. On top of that, that's not nothing, but it shifts work to quads and skips glutes. If you can't hit depth at rep 80, rest. Or do fewer reps with integrity That alone is useful..
No Progressive Overload
Once you can do the whole thing clean in 15 minutes, it's easy. So add a 10k run (carefully), wear a backpack, or move to one-arm push up variations. And easy doesn't change you. Otherwise you plateau and wonder why.
Practical Tips / What Actually Works
Skip the generic advice. Here's what actually works if you want to try this without regretting it.
- Start with 50-50-50. Seriously. Test the waters. The jump from 50 to 100 is bigger than it looks.
- Use a deck of cards. Flip a card, do that many of the suit's move.
