⚠ Medical Clearance — Read Before You Start
Press-ups place sustained load on the shoulder joint, elbows, wrists and chest. Performing them every day for thirty consecutive days without adequate recovery significantly increases the risk of overuse injury, particularly in the rotator cuff and elbow tendons.
This challenge is not suitable for anyone with a history of shoulder impingement, rotator cuff problems, wrist pain, elbow tendinopathy, or recent upper body injury. It is also not suitable for complete beginners who have not built any baseline of upper body strength.
Consult your GP before attempting this challenge. If you have any cardiovascular condition, Type 1 or Type 2 diabetes, or any joint problem in the upper body, medical clearance is not optional. oldschoolPT accepts no liability for injury arising from this challenge.
Where This Started — A Personal Story
I have loved press-ups since I was a child. Growing up, they were currency — you could do them anywhere, against anyone, with nothing. I remember press-up competitions with siblings and friends, particularly on cold family holidays when there was nothing else to do and someone decided the best way to pass the time was to see who would drop first. I was usually last to drop. That felt like something.
At school I excelled at them. Not because I was particularly big or strong — I was neither — but because I had figured out something that takes some people years to learn: press-ups are largely a mental exercise. The body gives up long before it has to. My personal best without stopping, when I was young and injury-free, was 85. I remember the number precisely because it felt so close to something significant and so far from it at the same time.
The challenge itself came from an unlikely place. I saw it on Facebook — back when Facebook was new, before challenges were a currency on YouTube and Instagram, before every fitness influencer had a thirty-day programme to sell. Someone had posted about doing 100 press-ups a day for a month and I thought: I can do that. Over those thirty days the most I managed in one unbroken set was somewhere between 40 and 50. But I finished every day. And by the end, my triceps felt extraordinary — that deep, satisfying pump that tells you something has genuinely changed.
I felt myself getting stronger week by week in a way that standard training does not always produce. Something about doing the same movement every single day, under progressive fatigue, forces an adaptation that split routines and rest days simply cannot replicate. The challenge is honest about what it is — no running, no gym, no equipment, not even a mat if you do not have one. Just you, the floor, and thirty days of showing up.
I have not yet managed 100 consecutive press-ups in one unbroken set. That remains the goal — and I want to be completely honest about that, because too much fitness content online only ever shows the success. I am fifty years old. I have had two ACL reconstructions. The body I am working with is not the one that once managed 85 in a playground. But the attempt is real, the progression is real, and eventually — filmed from day one — I will document what actually happens.

What the Challenge Does to the Body
Press-ups are one of the most complete upper body exercises available. They work the chest, anterior deltoids, triceps and core simultaneously — and when performed daily under progressive load, the adaptations are significant and fast. By the end of week one you will notice the earlier sets becoming easier. That is not imagination. That is the neuromuscular system adapting to a movement pattern it is now doing every single day.
By week two the triceps will feel like they belong to someone else — stronger, fuller, more responsive. The chest will be noticeably tighter and more developed. The shoulder complex will be working hard, which is why warm-up and cool-down from week two onward are non-negotiable. This is not a suggestion. Shoulder injuries from overuse are slow to heal and easy to pick up when fatigue is accumulating daily.
The jump from week three to week four — 30 to 50 press-ups per day — is where this challenge separates the committed from the casual. Fifty press-ups a day, every day, after three weeks of continuous training, is genuinely demanding. But it is also where the real strength gains happen. And the final days at 100 — even in multiple sets — will feel like something you earned.
The Challenge — Week by Week
Each day complete the target number of press-ups. They do not all have to be in one set — break them into as many sets as needed. The goal over time is to reduce the number of sets required. 100 in one unbroken set is the ultimate target. Getting there takes longer than 30 days for most people. But 30 days is where it starts.
Week 1 — Days 1 to 7 — Building the Habit
Do not be tempted to do more than 10 in week one. The progressive overload here is the point — the body needs to adapt to daily press-up stimulus before the numbers go up. Write down every session: how many sets, how it felt, whether form held throughout. That log will mean something in week four.
Week 2 — Days 8 to 14 — Building Endurance
Spend 5 minutes warming up the shoulders before each session — arm circles, chest openers, a few slow shoulder rotations. This is not optional from week two onward. Overuse injuries to the rotator cuff are the most common problem in this type of challenge and they are largely preventable with a proper warm-up.
Week 3 — Days 15 to 21 — Pushing Capacity
Add a cool-down this week — chest stretch, tricep stretch, shoulder cross-body stretch. Hold each for 30 seconds. The muscles are working every day without full recovery and they need the additional attention. Anyone who skips the cool-down in week three is making week four significantly harder than it needs to be.
Week 4 — Days 22 to 28 — Testing Limits
This is the week most people either find what they are capable of or discover they left too much in reserve in the earlier weeks. Fifty press-ups daily, after 21 consecutive days of training, is not something most people will ever attempt. You are already somewhere most people have never been. Finish the week.
Final Days — Days 29 and 30 — The Target
Completing this challenge — even partially — places you in a very small group of people. Most will never attempt it. Some will start and stop. You showed up every day. That is the point of the whole thing. Rest for a few days after day 30. Then come back stronger.
How to Do a Press-Up — The Basics
A press-up is a bodyweight pushing exercise that trains the chest, triceps and anterior deltoids. It requires no equipment, no space and no setup. Done correctly, it is one of the most efficient exercises available. Done sloppily, it is largely a waste of time and an injury waiting to happen.

Video — Being Added
I have footage of myself attempting this challenge. It is not polished. It is not edited. It shows exactly what it looks like when someone who has not yet managed 100 in one set turns up every day and does the work anyway. When it is ready it will appear here — uncut, honest, and exactly what oldschoolPT is about.
Ready to Start?
You need nothing except floor space. Start tomorrow morning. Ten press-ups. Write it down. Show up the next day and do it again. That is the whole plan for week one. Everything else follows from that.
