Real lifters, real results

Lifters Who Finally Started Moving Again

Clients who were stuck for months, in their own words.

Jonah's transformationIn his own words

Sean's transformationIn his own words

I'd been lifting for about three years by the time I found Gavin, and I looked exactly the same as I did when I started. It was humiliating. I'd go to the gym, do whatever routine I saw on TikTok or Instagram that week, and leave feeling like I had worked hard, but I had nothing to show for it. I was the definition of a perpetual beginner. Gavin completely dismantled my approach. He identified that my programming was random, lacked progressive overload, and was full of junk volume, then put me on a structured, periodized program built around compound movements. Within three months I had added significant, visible size, particularly to my chest and back. His feedback on my form was incredibly precise. He didn't just give me a program. He gave me an education. Maverick

Who you work with

I am Gavin, and I have coached lifters at every level.

Over 80 client transformations, from complete beginners taking their first real steps to seasoned intermediates who had been stuck for months. Whatever level you are at, I have almost certainly coached someone who started exactly where you are now.

I listen first, then I build everything around the person in front of me. Every training block, calorie and macro target, micronutrient goal, and supplement protocol is anchored to peer-reviewed research, then stripped back until it is impossible to misunderstand. We track the markers that actually matter, from strength and bodyweight trends to recovery, sleep, and bloodwork, so nothing is left to guesswork. No broscience. No cookie cutter plans. No timelines the science cannot back up.

80+ client transformations and counting.

Why nothing has changed

Your Lifts Have Not Moved in Months. It Was Never How Hard You Work.

You have switched splits, followed the big guys, and tried what the influencers swore by. None of it was built for you. Here is what is actually capping you.

Too much junk volume

Piling on sets you cannot recover from feels productive and quietly stalls you. More is not the answer when recovery is the bottleneck.

A program built for someone else

Cookie cutter plans assume your body, your recovery, and your schedule. They were never designed around the lifter you actually are.

Nobody calling the shots with you

Doing it alone means second guessing every decision. Without an expert eye on your periodization, fatigue management, and stimulus to fatigue ratio, you keep changing variables before any of them get the chance to work. The progress you are missing lives in the details most lifters never know to look for.

The method

Science Plus Simplicity. Four Steps.

Training has been overcomplicated for years. My job is to cut it back to what the research proves drives results, and make it impossible to misunderstand.

STEP 1

Find the leaks

We audit your current training, recovery, work schedule, and nutrition. Most stalls come from junk volume you cannot recover from and poor exercise selection.

STEP 2

Strip the junk

We rebuild training around mechanical tension and progressive overload. Fewer key lifts, hard sets taken close to failure, and planned progression you can measure week to week.

STEP 3

Align the food

Individualized nutrition built around recomposition and your real schedule, with calorie, macro, and micronutrient targets dialed to you. Where it helps, we use bloodwork and health markers to find what is quietly capping your energy and recovery, then fix it with food first and a supplement protocol only where it earns its place.

STEP 4

Mentor the decisions

Every week, on a live call, we make the calls together so there is zero guessing. You stop second guessing and start operating with certainty.

The Summit Coaching Guarantee

Hit your goal, or I keep coaching you free.

On our first call we set your specific, measurable 12-week goal together, calibrated to a realistic rate of progress for your body. That target goes in writing. Do your part across the full 12 weeks, and if you do not hit it, I keep coaching you free for up to 6 more weeks until you do.

Your part means attending your calls, training the plan, hitting your nutrition, and staying coachable. Your logs and check-ins are the evidence. This protects the clients who do the work.

Honest fit check

Is This Actually For You?

This is for you if

You have trained seriously for a couple of years and know your way around a gym
Your key lifts and physique have been flat for months despite the effort
You are willing to log your training, food, and check-ins honestly
You want a coach making the calls with you, not another template to follow alone
You are ready to invest in solving this properly

This is not for you if

You are brand new to lifting and still learning the basics
You want a free program or a quick fix without changing your habits
You are not willing to log your work or show up to your calls
You want someone to do it for you instead of with you

Before you apply

Questions Lifters Ask Before They Apply

What kind of results can I actually expect?

A specific, measurable target we set together on call one, calibrated to your body and your timeframe. That could be real weight on your key lifts, a leaner and more muscular physique, or the exact result you walk in chasing. We put it in writing, and it is what the guarantee is measured against.

How is this different from every program I have tried?

Every program you have tried was built for someone else. This is built around your body, your recovery, and your schedule, and every week we make the training and nutrition decisions together on a live call. You stop guessing.

How does accountability work?

A weekly 1-on-1 call, a weekly check-in on your numbers and photos, form reviews on the videos you send, and direct message support between calls within a set response window. You are never left to figure it out alone.

What is the investment?

It depends on your situation, which is exactly what the call is for. Coaching runs anywhere from $3,500 up to $12,000 depending on how much support you need and how long we work together. We map the right plan for you on the call, and I only take it further if it is genuinely a fit.

Is there a guarantee?

Yes. We set your measurable 12-week goal in writing on call one. Do your part, and if you do not hit it, I keep coaching you free for up to 6 more weeks until you do.

Can I do this with a demanding job?

Yes. Your training and nutrition are built around your real schedule and equipment, not a template that assumes you live in the gym and the kitchen.

Your lifts have been stuck for months. Let's break that in 12 weeks, or I coach you free.
