For lifters training 3 to 5x a week. Your lifts score nine strength patterns against your own targets, the lowest one is your weak link, and your program is built to attack it.
No call required. Your program within 24 hours. Cancel anytime.
Every method you've tried was chasing the symptoms; none of them found the weak link underneath your strength and power. That's the gap.
A free plan hands the same sets and reps to a springy athlete and a slow grinder. One of them is wasting their time. Usually both. It can't account for what it never measured.
Adding sessions or chasing PRs builds fatigue, not progress. If your weak link stays untrained, more volume makes it worse. You get more fatigue instead of progress.
Nobody ever tested you. It was never that you did not try hard enough. You were trying to solve the wrong problem.
The same system is used for all coached clients and is now built for self-serve within a membership.
A short intake, then your Force Profile in the app. It scores nine strength patterns against your own targets and names the lowest one. The Jump Profile too, when your goal calls for it.
Dries reads your profile and matches you to the program built for that weak link and your goal. It is in your app within 24 hours: real athletic strength and power work, 3 to 5 sessions a week.
You retest strength, power, and movement. Your weak link moves; the next program targets the new one, and your coach is in the community the whole way. Progress is measured, not guessed at.
Your Force Profile scores nine strength and power patterns against your own targets, then finds the single lowest one. Nine possible problems, nine matched solutions.
Weight and reps. The app works out the rest. The closer to your limit, the sharper the profile.
Never lifted at all? Then there is nothing to screen yet. You start on the Athletic Foundation Builder: 12 weeks, 3 to 5 sessions a week, of athletic strength, power, and single-leg work that builds you up everywhere at once, so you hit your first retest with real numbers.
Movement, Jump, and Conditioning profiles are yours to run too, and together they build one card that names the single quality holding everything else back. Strength without range is restriction. Strength without coordination goes nowhere.
Below is my own block, running right now, straight out of the app.
This is not the coached programme with pieces removed. It is a different deal: you hold the controls.
Force, Movement, Jump and Conditioning, whenever you want, as often as you want. No booking, no waiting on a coach's calendar.
Equipment missing, shoulder cranky, gym busy. Swap the movement in the app and keep the session intact.
Pick up to eight daily trackers from sleep, energy, stress, nutrition, load and pain. Yours to change any day.
Members only. Everyone in it is training their own weak link, so the questions are specific and so are the answers.
Ten minutes of testing, a program built for what it finds, and 14 days to change your mind.
See the two plansFor years, I chased a lean, muscular physique and the big three. The numbers went up, and so did everything I didn't want. I got even tighter. I felt heavy and slow. And eating for that size pushed my gut health further in the wrong direction. I was "strong," and I'd never felt less athletic.
In early 2025, I got the opportunity to prep athletes for the NFL Combine, which showed me what real athletic training looks like and put my weak links right in front of me. I'd built one quality, big-three strength, and ignored the rest. So that's what I changed: strength isn't just the big three, it's athletic, it's unilateral, and the big three.
But here's where it really matters. I took everything and applied it to myself and my clients. I'm not stronger on the big three than I was. But I'm faster, more explosive, more mobile, and more athletic than I've ever been, and my gut is in a much better place. And the results my clients achieved. Issues that I couldn't seem to figure out suddenly all made sense.
That's the GP Method: I find the weak link holding you back, whatever it turns out to be, and point your training straight at it.
These are some of my coached clients, running the exact system that is inside the membership.
Post-ACL surgery, a full rebuild. We profiled what the knee had cost him, trained it back in order, and worked his nutrition alongside it. He is racing Hyrox now.
Fast on the pitch but weak in the gym, and held back by knee pain. We profiled the weak links behind it, built his strength around them, and a few months later, the knee pain was gone, and strength and performance improved significantly.
Same program, same coach, same full access on both. Go for 3 months, and you also get the complete Nutrition Mastery course included on top of a lower monthly price.

What is collected. When you visit: technical data such as IP address, browser, device and pages viewed, plus the advertising identifiers below. When you join: name, email and billing details, with card details going directly to Stripe and never stored by Coach Dries. When you use the app: the training and health information you enter, including lifts, sets and reps, test results, measurements, check-in answers and goals. When you email: the content of what you send.
Why. To run your membership and build your program, to take payment and handle refunds, to send membership email and marketing email you asked for (every marketing email has an unsubscribe link), and to measure how this page performs.
Who it is shared with. Only the services needed to run the business: Stripe for payments, MailerLite for email, Leadpages for hosting this page, Supabase and Cloudflare for the GP Platform app and its data, and Meta through the pixel on this page for advertising measurement. Your training data is never sold and never shared with other members.
Cookies and the Meta pixel. This page runs the Meta pixel, which sets cookies and reports page views back to Meta so ads can be measured. You can block it in your browser or through your Meta ad preferences without losing access to anything here.
How long. Your account and training history are kept while your membership is active, and afterwards so your profiles are still there if you come back. Ask for deletion at any time and it is removed. Payment records are kept as long as tax rules require.
Your rights. You can ask to see, correct, export or delete your data, and withdraw consent for marketing email at any time. Email the address above and it is handled within 30 days.
The GP Method is not intended for anyone under 16. If this policy changes, the date above changes with it.
Last updated 22 July 2026. These terms cover the GP Method membership, sold by Grossen Performance (Coach Dries). Joining means you accept them.
What you are buying. A membership to the GP Platform: a periodised training program matched to your Force Profile and goals, the Force, Movement, Jump and Conditioning profiles, workout logging and PR tracking, the nutrition and check-in tools, the Self Hub, the members community and your course library. Programs are matched from proven templates built for each weak link, not written from scratch for you individually. Fully bespoke one-to-one coaching is a separate service (GP Core and Prime).
Price and billing. Monthly €59, billed every month until cancelled. Three months €149, billed every 3 months until cancelled, including the Nutrition Mastery course. Payment is taken through Stripe, prices are in euros, and renewal is automatic unless you cancel first.
Cancelling. Cancel at any time. You keep full access until the end of the period you have paid for and you are not billed again. Your profiles and training history stay on your account if you come back.
14-day guarantee. If you do not think it is worth continuing, for any reason, message within 14 days of your first payment and you get a full refund.
Your account. Your login is for you. Do not share it, and do not redistribute, resell or republish the programs, courses or profile results. You keep ownership of the data you enter and hold a personal, non-transferable licence to use the content while your membership is active.
Health and training risk. Strength training carries risk. The GP Method is coaching and education, not medical advice, and nothing in the app diagnoses or treats a medical condition. Check with a doctor before starting if you have an injury, a health condition or any doubt. You train at your own risk and are responsible for your own technique and load selection.
What is not promised. Results depend on your training, recovery, nutrition and consistency. Client results shown on this site are real and individual, and are not a guarantee of what you will achieve.
Access may be ended, with a pro-rata refund of any unused paid period, if an account is shared, content is redistributed, or a member behaves abusively toward the coach or the community. These terms and the price may change; existing members are told by email before a price change applies.
