Story
From hospital bed to Men's Physique — built for lifters who mean business.
Gabriel Tira
At 15, I was 100 kg. At 19, Crohn's disease put me in a hospital bed at 59 kg.
I've lived both extremes of “not in control”.
In 2021, after 12 years of trial and error, I made a decision: master fitness clean, fast, and sustainable — or die trying.
I got certified, coached for 4 years, and almost stepped on a Men's Physique stage. Then I won a 6‑week body recomp challenge out of 42 competitors.
But something was still off. I was training hard and tracking dumb.
🥹 Friends clowned my calves — fair. Not anymore.
So I built what I needed: JO AI — a 24/7 coach that plans the work for you.
It auto‑periodizes based on your recovery and weak points, tells you what to do next, and tracks your progress so you can see the gains stacking.
You focus on the reps. JO handles the plan.
If you're a beginner chasing an aesthetic body, or an advanced lifter looking to break through the plateau — this is for you.
