Meet your coach
Robson Etuke Diamond doesn't teach theory he hasn't tested. He competes in Muay Thai himself — so every combination, every drill and every round he puts you through has been pressure-tested under the lights, in front of a crowd, with someone trying to take his head off.
He is a Muay Thai competitor, CPT / S&C coach, ISSA Strength and Conditioning certified, and a HYROX coach. He runs Muay Thai and boxing sessions at Unity Fitness Harbourfront and Triumph Muay Thai in Toronto, blending the traditional art — stance, teep, clinch, the eight limbs — with modern strength work, so you get faster, sharper and harder to hit at the same time.
First time in a gym or preparing for a bout, the standard is the same: show up, work hard, leave better than you came in.

The failure point
Your skill means nothing if your engine shuts down.
This is conditioning built around combat demands—not random suffering dressed up as fight preparation.
For fighters who gas out
You look sharp early, then your feet slow, your guard drops, and every decision costs more. Build repeatable power and recover between exchanges.
For coaches who need a system
Stop stitching together hard sessions with no progression. Follow a clear eight-week conditioning structure you can understand and execute.

Review 56
Rob is an exceptional boxing coach. We’ve been working together for the last six months and I have learned a lot specifically technique, self-defense, mobility, and rhythm. My conditioning has improved tenfold, and on top of that I also lost about 14 pounds. I feel much stronger and I cannot be more thankful to Rob for his excellent coaching.

Rob makes sure your heart rate is elevated! Constant movement in your warmup, and you not only learn proper technique - both offensive and defensive - but why it makes sense from a fighters perspective. He puts you to work!!!

The trainer was excellent! So encouraging and supportive. Better exercises for strength building. I found it better than my classes with Manuel. Would love to attend more of his sessions.

Booking & rates
Rates depend on the format — group class, private coaching, or a full training block — so they're quoted on request. No pressure, no surprises: tell us what you're training for and you'll get a straight answer and a plan that fits it.
Questions, answered
Everything new students usually ask before their first session.
I've never trained before. Can I start?
Yes — that's exactly what Beginner Foundations is for. You'll learn stance, guard, footwork and the basic strikes step by step, at your pace. Most people who train with Robson walked in as complete beginners.
What do I need to bring?
Workout clothes, a water bottle and a towel. If you own boxing gloves and hand wraps, bring them. If you don't, mention it in your message when you book and we'll sort you out for your first sessions.
Where do sessions take place?
Robson coaches out of Unity Fitness Harbourfront and Triumph Muay Thai in Toronto. Exact location and times for private sessions are confirmed when you book — ask through the live Primitiva Muay Thai Facebook page in Contact.
What's the difference between Muay Thai and boxing?
Boxing is the hands — jab, cross, hooks, uppercuts, plus head movement and footwork. Muay Thai, the "art of eight limbs," adds kicks, knees, elbows and the clinch. Primitiva Muay Thai sessions train both, so your striking is complete.
Do you offer private training?
Yes. Private one-on-one coaching is available by appointment for technique work, conditioning, or full fight preparation. Ask through the live Primitiva Muay Thai Facebook page in Contact — rates are quoted on request.
I'm training for a fight. Can you coach that?
That's home turf. Robson competes in Muay Thai himself, so fight preparation covers technical game-planning, hard conditioning, and the mental side of fight camp — built around your bout date.
How do I book or ask about rates?
Use the Primitiva Muay Thai Facebook page, Instagram @primitivamuaythai, or email 
[email protected]. Tell us what you're training for and you'll get times and a straight rate quote back.
