Ever tried to just keep going? No fancy apps, no expensive heart rate monitors, just you and a number that feels like it’s getting further away with every breath. Honestly, the counting to 100 workout is one of those things that looks deceptively simple on paper but feels like a total beatdown by the time you hit sixty. It’s basically exactly what it sounds like: you pick an exercise, or a circuit of them, and you don’t stop until you hit triple digits.
People usually underestimate it. They think, "Oh, a hundred squats? I can do that in my sleep." Then their quads start screaming at rep forty-five.

This isn't just about mindless repetition, though. It’s a specific training modality often referred to as "Centurion" training or high-volume endurance work. Coaches like Dan John have talked about the psychological shift that happens when you commit to a high-number set. You stop overthinking your form in a way that paralyzes you and you start finding a rhythm. You have to. If you don't find that flow state, you’re going to quit before you even see eighty.
Why the Counting to 100 Workout Actually Works
Most gym sessions are broken into nice, neat little packages. Three sets of ten. Five sets of five. We love the number ten. But your body doesn't actually care about the number ten. It cares about time under tension and metabolic stress.
When you perform a counting to 100 workout, you’re pushing past the point where your aerobic system usually hands the baton to your anaerobic system. You’re forcing a level of muscular endurance that standard gym routines just don’t touch. By the time you get to rep seventy, your slow-twitch muscle fibers are exhausted, and your body starts recruiting fast-twitch fibers just to keep the movement going. It's a weird, painful kind of magic.
There's a study often cited in the Journal of Strength and Conditioning Research that looks at high-volume versus high-intensity. While lifting heavy builds raw power, this kind of high-volume work flushes the muscles with blood—what bodybuilders call "the pump"—which can actually help with connective tissue health and sarcoplasmic hypertrophy. Basically, it makes your muscles look fuller and your joints feel a bit more lubed up, provided you aren't ego-lifting.
The Mental Game of Triple Digits
Let's be real: doing 100 of anything is boring. It's tedious.
That boredom is actually the point. Modern fitness is so full of "muscle confusion" and high-octane music that we’ve forgotten how to just suffer through a monotonous task. This workout builds "mental calluses." When you’re at rep eighty-two and your lungs are on fire, but you still have eighteen to go, that’s where the real growth happens. It’s not in the muscle; it’s in the head. You learn how to negotiate with yourself. You learn how to not listen to the voice telling you to put the bar down.

Breaking Down the Methods
You don't just walk in and do 100 deadlifts. Please, don't do that. Your lower back would never forgive me. There are smarter ways to structure a counting to 100 workout depending on what you’re trying to achieve.
The Straight Shot
This is the purist version. You pick one move—usually something bodyweight like pushups, air squats, or kettlebell swings—and you go until you hit 100. If you have to pause, you pause in the "active" position. For pushups, that’s the plank. For squats, that’s standing. You don't sit down. You don't check your phone. You just breathe and reset.
The "10x10" German Volume Variation
Technically, this is 100 reps, but it’s broken up. Charles Poliquin popularized this for massive hypertrophy. You take 60% of your max and do ten sets of ten with exactly 60 seconds of rest. By set seven, you'll realize why people dread this. It’s a mathematical way to ensure you hit that 100-rep threshold without your form falling apart into a dangerous mess.
The Chipped Method
I find this one the most tolerable for beginners. You "chip" away at the 100. Maybe you do 20, then 15, then 10, then 5, and repeat until the total is 100. It’s a psychological trick. You’re still doing the work, but you’re giving your brain small wins along the way.

Common Pitfalls (And How to Not Get Hurt)
The biggest mistake? Picking the wrong weight.
If you try to do a counting to 100 workout with your usual 8-12 rep max, you are going to fail miserably or get injured. This requires a significant ego reduction. If you’re doing 100 reps of goblet squats, you might only need a 20lb kettlebell, even if you usually squat 200lbs. The fatigue accumulates exponentially.
- Loss of Form: Once you hit rep 60, your back might start to arch. Your knees might cave. Stop. Take five seconds. Fix your posture. A hundred bad reps are worse than fifty good ones.
- Neglecting Breathing: People hold their breath when they get tired. That’s a fast track to passing out. You need to time your exhales with the exertion phase of every single rep.
- Too Much Frequency: Do not do this every day. This is a "once or twice a week" shock to the system. Your nervous system needs time to recover from this much volume.
Real World Examples of the 100 Rep Finish
Some of the most legendary athletes use this. Look at the "Murph" CrossFit workout—it involves 300 air squats, but it’s often broken down into segments that feel like a continuous counting to 100 workout for each movement.
I remember reading about old-school wrestlers who would do 100 "Hindu squats" every morning. They didn't have fancy squat racks. They just had the floor and a high tolerance for pain. Their cardio was legendary not because they ran marathons, but because their legs were conditioned to never stop moving.
The "100-Rep Finisher"
You don't have to make the whole workout about counting to 100. A lot of bodybuilders use it as a "finisher." You finish your heavy bench press, then you grab a pair of light dumbbells and do 100 lateral raises. It flushes the area with lactic acid and forces a massive amount of blood into the lateral deltoid. It burns like crazy, but the results speak for themselves.
Sample 100-Rep Routines to Try
If you're looking to jump in, don't overcomplicate it. Pick one of these and see how you feel tomorrow. (Spoiler: You'll feel sore).
The Bodyweight Burner
- 100 Air Squats (Focus on depth)
- 100 Pushups (Break into sets of 5 or 10 if needed)
- 100 Sit-ups (Old school, keep the core tight)
- 100 Lunges (50 per leg)
The Kettlebell Chaos
- 100 Kettlebell Swings (This is a classic for a reason. It builds a bulletproof posterior chain).
The "Century" Pump (Arms and Shoulders)
- 100 Bicep Curls (Use a very light weight, like 10-15lbs)
- 100 Tricep Extensions
- 100 Face Pulls
Actionable Steps to Start Today
- Choose your "Why": Are you doing this for mental toughness, a quick cardio burn, or a muscle pump? This dictates your exercise choice.
- Pick ONE movement: If you’re new to this, don't try to do a whole circuit. Just try to hit 100 reps of one thing.
- Set a Timer: Don't rush, but don't dawdle. See how long it takes you to hit 100. Next week, try to beat that time by ten seconds.
- Track the Breaks: Write down how many times you had to stop. If you stopped six times today, aim for five next time.
- Prioritize Recovery: Drink more water than usual and get some extra sleep. High-volume work like this creates a lot of metabolic waste that your body needs to clear out.
The counting to 100 workout is honestly a reality check. It strips away the ego and leaves you with nothing but your own breath and the next rep. It’s cheap, it requires almost no equipment, and it’s effective. Start with something simple like bodyweight squats and see if you actually have the discipline to finish all 100 without cutting corners. You might be surprised at how loud that voice in your head gets at rep seventy-five. Don't listen to it. Just keep counting.
