✕Motivates with hype, not science

✕No progress tracking between sessions

✕Results plateau after a few weeks

01
Science over opinion. Every programme is built on exercise physiology and peer-reviewed research — not trends or guesswork.
02
Results over aesthetics. The focus is measurable change — strength, body composition, energy, and long-term performance.
03
Respect for your time. Sessions are precise, efficient, and built around your schedule — not the other way around.
04
Long-term partnership. This is not a short-term fix. It's a system that evolves with you — for life.

✓ Verified Client

I'd tried 3 PTs before Flaviano. None of them came close. He rebuilt my entire approach from scratch — the science, the nutrition, the mindset. I lost 12kg in 4 months and I've kept it off. Best investment I've made in myself.

As a busy entrepreneur I needed results without wasting time. Flaviano programmes every session with a purpose — every set, every rep has a reason. Six months later I'm in the best shape of my life. The app makes it all seamless.

Online coaching that actually works. Weekly check-ins, instant feedback on the app, adjustments when my schedule falls apart — Flaviano treats you like his only client. Three months and I'm unrecognisable. Completely worth it.

I'm based in North West London (NW6). I train clients across London — in private gyms, home gyms, and Westfield-area facilities. I also offer fully remote online coaching for clients across the UK and internationally. Location is never a barrier.

Every programme is built from scratch using exercise science — not a generic template. I track every variable, explain every decision, and adjust continuously. You'll understand your own body better after a month with me than most people do after years in the gym.

Absolutely. Beginners often see the fastest results because there's so much room to grow. Your programme will be designed exactly for your current level, building foundations first — movement quality, baseline fitness, and sustainable habits.

Most clients notice measurable changes — increased strength, better energy, improved body composition — within the first 4–6 weeks. Visible physical transformation typically shows clearly between weeks 8–12, depending on your goals and starting point.

Yes — nutrition guidance is included in all packages. For VIP clients, this includes a detailed macronutrient protocol tailored to your training phases. I use evidence-based approaches, not fad diets or extreme restrictions.

I use Trainerize — a professional coaching platform that delivers your workouts, tracks your progress, syncs with Apple Watch and other devices, and keeps us connected between sessions. You'll have everything in one place on your phone.

No long-term contracts. Online coaching is month-to-month and can be cancelled with 30 days' notice. I recommend a minimum of 3 months to see meaningful results, but there's no lock-in — the programme speaks for itself.

Your coaching
ecosystem.

Every client gets access to the Trainerize platform — the world's leading fitness coaching app, trusted by over 150,000 trainers globally.
