Is this you?
Work, family, a packed calendar. Training happens when there’s time, which often means it doesn’t.
You show up and work hard, but progress is slow because nothing ties it together.
Trials, selection or a new season. Training, recovery and nutrition need to work as one.
More energy, better sleep, a clearer head and a body that’s built to last.
What's included
Training is a small slice of your day. We build around the rest of it, so your body and your head perform at their best.
A plan built around your goals and your calendar.
Fuelling built around your training and your life.
Protocols that fit your schedule.
Mindset training for pressure moments.
Systems that hold up all season, all year.
1:1 coaching contact as you progress.
How It Works
A free 30-minute call. We talk about your goals, your schedule and where you are right now.
If we’re a fit, you get a plan built around your week: training, nutrition and recovery.
You’re not on your own. Direct coaching and adjustments keep you moving forward.
Meet the Coaches
Real People. Real Results.
★★★★★
Back-to-back games used to wreck me. Now my legs feel fresh into the second half of the season, and my recovery days actually mean something.
Rory
★★★★★
Peter built a plan around my season, not against it. My vertical and my court speed both improved without adding extra gym days I didn't have time for.
Rita
★★★★★
I used to fade by the third period. Now my legs hold up for every shift, and my own coach has noticed the difference.
Zoe
★★★★★
Getting ready for trials felt impossible to plan on my own. RT Athletics gave me a real structure for training, eating, and recovering that actually fit around my week.
Jamie
★★★★★
RT Athletics helped me improve my performance at a top university level. My conditioning, my recovery between games, all of it stepped up once I had a real structure behind it.
Amadou
★★★★★
I came in without a specific sport in mind, just wanting to get faster and stronger for tryouts. RT Athletics gave me a level of structure I never had training on my own.
Leon
★★★★★
I hadn't lifted consistently in years. Full Body got me back in the gym without overwhelming me — three months in and I'm stronger than I was at 25.
Felix
★★★★★
First 5K to First 10K took me from barely jogging to finishing my first real race. I never thought I'd call myself a runner.
Sabrina
★★★★★
Built to Perform fits perfectly around my work week. I'm stronger, I sleep better, and I actually look forward to training now.
Julian
★★★★★
Shift work made consistency impossible until I found a plan that worked with just 3 days a week. Down 12kg and stronger than I've ever been.

PATH 03
Three levels of race readiness — Challenge, Perform, Win
Hybrid strength-and-endurance racing prep, built as a competitive ladder rather than a single plan — you train to survive it first, then to perform, then to actually win your heat.
01
Built to Challenge
Beginner-friendly — lays the foundation for long-term progress by reshaping strength and cardiovascular health from the ground up. Builds consistency, control, and capacity so you're ready to progress into Level 2 and 3 as your fitness evolves.
02
Built to Perform
Intermediate — builds on Level 1 with more volume and intensity, pushing body and performance forward while staying smart and consistent. Sets the stage to advance into Level 3, where performance and intensity meet precision.
03
Built to Win
Advanced — where performance meets precision. Adds intensity, explosiveness, and complexity for those who've built the base and are ready to push limits, dialing in performance, conditioning, and resilience at a high level.

Start free trialPeter SchaaleFounder & Performance Coach
Coach · Founder
I’m Peter Schaale — ex-professional footballer, hybrid athlete and founder of Relentless Theory. I won’t hand you a plan I wouldn’t run myself.
A former professional footballer turned performance coach. Licensed Fitness Coach, Nutritionist, Personal Trainer & Performance Coach. I’ve coached 100+ athletes — youth, university and pro level, in person and online.
I live the hybrid life: I run long, including ultramarathons, and lift alongside it. The other 22 hours get the same care — food, sleep, routines and recovery are planned, not left to chance. I ran 60km on my 30th birthday to raise money for men’s wellbeing, and the next ultra is already on the calendar.
Structured programs you can start today — running, strength or hybrid — with clear sessions, progressive weeks and injury prevention built in. Want me in your corner? 1:1 coaching wraps nutrition, sleep, habits and mental resilience around your training.
Healthy body, healthy mind — they work as one, and you perform at your best when you’re in tune with both. Results come from showing up, not from shortcuts: a plan you can actually follow, progress that compounds week after week, and a mindset that holds when motivation doesn’t. Same approach for a pro roster and a first-time 5K runner.
Relentless isn’t intensity. It’s consistency.
Justyn MeilleurCoach & Co-Founder
Coach · Co-Founder
I’m Justyn Meilleur — coach and co-founder of Relentless Theory. I come from American football and I’ve been training with weights for over 20 years. Today I do it around a packed schedule, a physical job and a family.
I’m a dad with a demanding, physical job. American football shaped how I train, and I bring 20+ years of strength training to everything I coach. I train every day and eat well — not as a hobby, but as a system that keeps me healthy, strong and present for my family.
I fit daily workouts and healthy nutrition into a full schedule. Short, focused sessions, simple meals, routines that survive long workdays. If it doesn’t work on a busy day, it doesn’t make it into my plan.
I coach people with busy schedules and physical jobs — people who are tired, short on time and still want to be strong and healthy. We build training and nutrition that fits your week, not the other way around.
Two decades under the bar taught me that consistency beats perfect. A plan you can repeat on a hard week beats a perfect plan you drop after ten days.
No perfect schedule needed. Just a plan that fits yours.
1:1 Performance Coaching
Training is a small slice of your day. 1:1 performance coaching is built around the rest of it — for athletes at youth, university, academy or pro level, and for anyone who wants to get more out of their daily performance: more energy, a clearer head and a body that’s built to last.
We work on what really drives how you perform: nutrition built around your life, sleep and recovery that fit your schedule, habits and routines that hold up when things get busy, and mental resilience for the moments that matter. Healthy body, healthy mind is the foundation — whether you’re preparing for trials and selection, or you simply want to show up as your best self every day.
