Jump higher, get a faster first step, be lighter on your feet, or all three. Pick one and train it for 12 weeks.

"Workouts are short but challenging. Even on days where I feel slow and sluggish I can still complete the workout. Program design is top notch."
If two of these sound like you, this is for you.
Every one of them skipped the same step: one goal, trained in the right order, for long enough to see it move. More drills don't close that gap.
A template gives a springy athlete and a stiff grinder the same jumps, sprints and sets. You get better at the program, not at moving.
More jumps, more sprints, more sessions. Without a plan for the next twelve weeks, harder just means more tired.
A drill from a video is fine on its own. Getting off the floor, applying force fast and reusing the bounce each need their own place in the week, in the right order.
You've put real effort in without ever knowing if it moved. Session one measures your goal. Week 12 measures it again. The guessing stops.
This is Peter, a client running the exact system you get: same tests, same platform.
BeforeAfterPost-ACL surgery, a full rebuild. Agathe profiled what the knee had cost him, trained it back in order, and worked his nutrition alongside it. He's racing Hyrox now.
Fast on the pitch but weak in the gym, and held back by knee pain. I profiled the weak links behind it, built his strength around them, and a few months later the knee pain was gone and his performance had moved with it.
Every screen you'll use, from session one to test day. Filmed on the platform as it is today.
The 12-week plan costs less and comes with the Nutrition course.
Everything you saw in the video comes with both plans.

Join, pick your goal, and start your first week. If you don't think it's worth continuing, for any reason, message me within 14 days and I'll refund you in full. No friction. I'd rather know why it wasn't the right fit than keep money I didn't earn.
For 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.
A few years ago, 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 yes, it's the big three too.
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 my clients got the same results. Issues I couldn't figure out before suddenly all made sense.
Ready on the GP Platform the day you join. Test day shows what moved.
Answer one question. The platform tells you which way to train your goal.
Three or four strength sessions a week, your pick, and one or two optional speed sessions, every set, rep, tempo and rest already written. Exercises sharing a letter run back to back before you rest.
Tap a session and the other phone opens it. Both screens scroll, the same way they do in your hand.
That was the last session of Block 1, Phase 1. Phase 2 is open now: 4 weeks, and your numbers carry over.
One more phase is queued behind it.
You recover from hard training faster than almost anyone, but your high drive runs you hot. Protect sleep and downtime so the intensity doesn't tip into burnout.
You do best on simple, structured, balanced meals and can lean toward fewer carbs. When you do eat carbs, put them after training.
› Creatine, 5g a day. Backs up your heavy, low-rep strength work.
› Caffeine before training, not late in the day.
› Magnesium before bed. Your high drive burns through it.
Log your sets like normal. Lift more than last time and the platform tells you, with a card you can share.
Finish phase one and phase two is waiting. Same goal, a bit more asked of you.
Your week 12 test shows what moved. Then you keep your goal, or pick a new one.
No scale, no counting grams. Palms, fists, cupped hands and thumbs, and rest days sort themselves out.
A short questionnaire tells you how you recover, eat and supplement best. It never changes your program.
No waiting around to find out what you paid for.
Your goal, a program built for it, and a test day at week 12 to prove it moved.
See the two plansThe 12-week plan runs one full block, twelve weeks of training, costs less per week, and comes with the Nutrition course.

You pick the goal. One block trains it. Every 12 weeks you test, and you choose what comes next.
Start nowLast updated 28 October 2026. Dries Grossen, operating as GP Coach Dries, is responsible for the data described here. Contact dries@grossenperformance.com.
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 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 28 October 2026. These terms cover the GP Method membership, sold by Dries Grossen, operating as GP Coach Dries. Joining means you accept them.
What you are buying. A membership to the GP Platform: a periodised training block for the goal you pick, 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. Blocks are written by Coach Dries for each goal and assigned automatically from the goal you pick. Fully bespoke online one-on-one coaching is a separate service.
Price and billing. €57 billed every 4 weeks until cancelled, which is 13 payments a year (members who joined at €59 keep that price). €147 billed every 12 weeks until cancelled, or €47 (the first 20 members) or €97 if you joined while a 24-hour price ran, which then stays the same for as long as the plan runs. The Nutrition: White Belt Mastery course is included with the 12-week plan for as long as you stay a member. 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 on the GP Platform 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.
Account termination and changes. 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.
