Get your power back.
Stop training around your body.
Start trusting it again.

For active adults who still train, play, and push, but feel stiff, slow, and held back. The GP Method finds exactly what's holding you back, then trains the cause. Not the symptom.

Sound familiar?

Stiff for two or three days after anything hard
That half-second hesitation before the sprint, the jump, the steeper run
One hip (or knee, or shoulder) you've learned to train around
Telling yourself it's just age. But not fully believing it
Doing less to avoid the soreness, which quietly makes you feel even older

It isn't age. It's a problem you haven't found yet. We find it first.

Sound familiar?

You still train. You still show up.
So why does your body feel like it's working against you?

If any of these feel a bit too accurate, keep reading.

You wake up stiff the day after a hard session. It takes two or three days before you feel right again. It used to take one.

There's a half-second hesitation before the sprint, the jump, the steeper run. Not pain exactly. Just a quiet signal that you don't fully trust the body anymore.

One side is always talking: a hip, a knee, a shoulder. You've quietly learned to train around it instead of fixing it.

You've tried stretching, foam rolling, the odd physio session. It helps for a few days. Then you're back where you started.

Part of you has started to think: maybe this is just what getting older feels like. But another part of you isn't ready to accept that yet.

Why nothing has worked

You haven't been treating the problem.
You've been treating the smoke.

Every method you've tried was chasing the spot that hurts. None of them asked why it hurts. That's the gap.

Stretching & foam rolling

Feels good. Doesn't hold.

You're targeting the symptom: the tight hip, the nagging knee. Tightness is usually a downstream signal. Stretch the downstream and the upstream keeps sending it.

Physio & massage

Short-term relief, same long-term story.

Manual therapy treats what's presenting today. Without addressing the pattern causing it, the presentation keeps coming back. Good for flare-ups. Not a fix.

Generic programs & apps

Can't solve a problem they can't see.

An app gives everyone the same plan. If your left side is doing 30% less work, the app doesn't know that. So it ignores it. So does your training.

The actual problem

You were guessing in the dark.

Nobody ever screened you. Without a diagnosis, every fix is a shot in the dark. It's not that you didn't try hard enough. It's that you were solving the wrong problem.

The GP Method

Three steps. No guessing.

The same system used with my closest coached clients, built for self-serve inside a membership.

Step 01

We find out what's holding you back.

A 30-second intake and a simple movement self-screen. No guessing: we see exactly where your power, mobility, or bounce has gone, and which side is the quiet problem.

Step 02

You train on a program built for you.

Built around your screen results, your goal, and the days you actually have. 2 to 5 sessions a week, all in the app. This is not a generic plan with your name on it.

Step 03

You progress on proof, not luck.

Retest every 3 months. The program updates to where you are now, not where you started. Ask both coaches anything in the community as you go.

What you get

Everything you need.
Nothing you don't.

The GP Method is designed to be the last training system you piece together from guesswork.

A hand-portion nutrition calculator with a daily tracker. No weighing, no grams. Plus, sleep and bodyweight tracking are built into your routine.

After you join

What happens
when you sign up.

Three things happen immediately. Nothing complicated.

You complete the intake and screen.

A short form and a simple movement screen you do at home. Takes about 10 minutes. This is what makes everything that follows actually work.

Your full setup lands in the app.

The nutrition plan tracker, sleep tracker, and all four hubs are ready the moment you open the app. Your training program is live within 48 hours. Chosen based on your screen results and your goals.

You start training. We're there as you go.

Log your sessions, ask questions in the community, and check in with either coach when you need to. No guessing, no silence.

Why Dries

I've lived this problem. Then I trained my way out of it.

Both hips were operated on at 19 years old as a Muay Thai athlete. Later, strong in the gym, but still tight, still limited, still nagged by the same hips long after surgery. I was doing everything "right" and still not feeling athletic or free in my own body.

Early 2025, a course in Tampa changed how I understood movement. I'd been training hard, but not training for how the body actually moves: on one leg, in rotation, in fast unpredictable moments. That's exactly why the nagging stuff never resolves.

I train five times a week now and feel more athletic than I ever have, including sprint training I'll keep doing for the rest of my life. My hips keep improving. I'm telling you because I know what it feels like to accept the wrong story about your body, and then prove it wrong.

There's a lot of bad information in the fitness world, and most people are quietly accepting slow, stiff, and careful as normal. It isn't normal. And it isn't fixed. The GP Method is how I help people prove that.

Real results

What happens when you train
the cause, not the symptom.

The membership is new. The system inside it isn't. It's the same screen, program, and retest loop I run with my coached clients.

"I started at 47 having never trained before. I couldn't do a Bulgarian split squat. Now I do FFE split squats with 14 kg on each side. His programs follow perfect logic, aimed at your goals. You always feel like he has your back."

After

"Every previous attempt had collapsed under court schedules and client dinners. This time the plan bent around my calendar instead of fighting it. My calories went up, not down - and I hit a 100 kg back squat PR."

Law firm partner

−15 kg fat · +5 kg lean muscle · Gained strength & muscle over years

These results came from direct 1:1 coaching. The GP Method runs the same system in membership form, with coaches present in the community throughout.

Questions

Answered honestly.

The things people ask before joining, with actual answers.

I've tried everything. Why would this be different?

Because everything you've tried treated the symptom. This starts with finding the cause, which means the first thing we do is screen you, not hand you a plan. If nobody has ever done that for you, the results can look surprisingly different.

Is this just mobility and stretching I can find on YouTube?

No. The GP Method includes strength, power, and performance training built around your screen results. Some of it will look like mobility work. A lot of it won't. The difference is it's specific to what you're missing, not generic content for a generic person.

How much time does this take each week?

Your program is built around the days you actually have: 2 to 5 sessions per week. Sessions run on average for 60 minutes. This is built for people with real lives, not people who train full-time.

How can an online coach fix something physical without seeing me in person?

The movement screen is designed to be done at home. It gives us, in combination with the intake, the information we need to choose the right program. It's not the same as an in-person assessment, but it's a significant step above guessing, which is what most people are doing.

How long until I see results?

Energy and sleep improve in weeks. Power and movement quality (the thing that removes the hesitation) typically takes 3 to 6 months of consistent work. That's why the first retest is at month 3. It's the earliest point where the numbers say something real. Anyone promising faster is selling something.

What if I get screened and find out something's actually wrong?

That's the point. Most people already know something isn't right. They've just never had it named. Knowing what's wrong is not a problem. It's a starting point. And it's far better than continuing to train around a problem you don't understand.

Maybe it's just my age. Is that realistic?

Some decline is real. Most of what people accept as age is actually disuse. Power and speed fade faster than strength, and most people stop training both long before they need to. The question isn't whether you can get it back. The question is whether you train for it or not.

Get your power back.
Stop training around your body.
Start trusting it again.

You still train. You still show up.
So why does your body feel like it's working against you?
