The Guarantee
Everything to gain, nothing to lose.
Most coaching asks you to pay first and hope it works. THRIVE 90 flips that. You pay weekly — and only if you feel you got the results and value you signed up for. That's a real results guarantee, in writing.
“If you don't get results you're happy with, you don't pay.”
1
Pay weekly, not upfront
No lump sums and no long lock-in. You're billed week to week as you train.
2
Only pay for results
If you don't feel you achieved satisfactory results — or got real value — you don't pay for that week.
3
The risk sits with me
I only earn when you win. That keeps me relentlessly focused on your outcome, not your invoice.
About Seth
Coached by someone who's been there.
I'm Seth — founder of Strength Syndicate and the coach behind THRIVE 90. I built this program for the person I used to be: stuck at a desk, low on energy, and tired of plans that ignore real life.
My philosophy is simple. Training should fit around your job, your family and your schedule — not the other way round. No fads, no punishment, no all-or-nothing. Just a personalised system that compounds into a body and a mindset you're proud of.
My goal with every client is the same: make you feel dominant in your own life again — stronger, sharper and more confident — and to stand behind that with a guarantee that puts the risk on me, not you.
