The 30-Day Challenge

My Story — Why I Did This and What Happened

The Covid-19 lockdowns did something to a lot of people's relationship with fitness. Gyms were closed, routines were destroyed, and for many the habit they had built over years simply evaporated. When things began to open up again there was a period — I suspect many people will recognise this — of feeling behind, feeling the gap between where you were and where you had been, and wanting to close it rapidly.

I was forty-five, a qualified personal trainer with three decades of training experience, and I designed this programme for myself. Not for clients — for me. Five kilometres and one hundred press-ups, every day, no rest days, for thirty days. I had never seen anyone else attempt this exact combination. The running alone is manageable for a fit person. The press-ups alone are manageable. Together, every day, with no recovery — that is something else entirely.

I filmed the sessions on a GoPro. The footage exists somewhere. Eventually it will be on the YouTube channel and you will be able to see exactly what this looks like in practice — not the highlight reel, not the days where everything went well, but the days in week two where every press-up felt like moving a car, where the legs were asking serious questions and the mind was louder than both of them.

I did not complete all thirty days. I got into week two or week three before the body overruled the mind. And I want to be honest about that, because I think the culture around fitness challenges online does everyone a disservice when it only ever shows completion. Getting to week two or three of this programme — at forty-five, with no rest days, running and pressing every single day — is not failure. Most people who read this page will never attempt it at all. I attempted it. I learned from it. And this summer, with video footage from day one, I am going to do it properly and show every day honestly.

"Most people never attempt anything. I attempted this at forty-five. That is the point."

What the Challenge Does to the Body

By the end of week one, the cardiovascular system has adapted significantly. The five kilometre runs begin to feel more manageable as the aerobic base develops rapidly under daily load. The press-ups begin to build genuine upper body endurance — the triceps, anterior deltoids and chest are working every single day without adequate recovery, which means they are adapting under constant stress rather than the standard stimulus-and-recover cycle.

Week two is where most people will encounter their first serious wall. The cumulative fatigue from seven consecutive days is compounding. The legs are heavy before the run begins. The press-ups feel significantly harder than they did on day one despite the body theoretically being fitter. This is not an illusion — it is the reality of training without recovery. The body is adapting but it is also accumulating damage faster than it can repair it.

By week three the body has either adapted sufficiently to continue or something has broken down. Injury risk is at its highest here — the knees, the shoulder complex, the elbow joints and the lower back are all under sustained stress. Stretching — particularly the chest, triceps, hip flexors and calves — is not optional from this point. It is the difference between finishing and not finishing.

What the programme produces, in those who complete it or come close, is a level of cardiovascular fitness and upper body endurance that standard training over the same period simply cannot replicate. VO2 max improves dramatically. Press-up capacity increases to levels most people will never reach through conventional training. Weight loss is significant. And the mental resilience built by showing up every day regardless of how the body feels is, in my honest opinion, the most valuable adaptation of all.

The Programme — Week by Week

Each day: 5km run (target 32 minutes) followed by 100 press-ups. Warm up properly before every session. Cool down properly after every session — this is non-negotiable from week two onward. The 32-minute target for the 5km is a guide, not a rule. Completing the session is the priority.

The Summer 2026 Attempt — On Camera

This summer I am attempting the full thirty days again. This time with video footage from day one. Every session filmed on the GoPro. Every day documented honestly — the good days, the bad days, the days where the body is screaming and the sessions happen anyway. The footage will be on the oldschoolPT YouTube channel as it happens.

Follow the channel and you will see exactly what this programme does to a fifty-year-old personal trainer with Type 1 diabetes and two ACL (anterior cruciate ligament) reconstructions. Not a highlight reel. Not a curated transformation story. The real thing, in real time.
