A1 The Story
From Havana
to Hialeah.
Rafael grew up swimming, running and riding in Cuba, where he reached the national triathlon team and raced the CAMTRI Iberoamericano. Triathlon taught him the body handles more than you think.
After moving to Miami he crossed the finish line of a full Ironman: 140.6 miles. In 2024 he opened 21 DOSE in Hialeah to bring that mindset to a 60-minute class.
No light show here. Just real progress, class after class: dopamine, oxytocin, serotonin, endorphins.

01
No egos
No leaderboard, no cameras. You compete against your own number from last week. Nothing else.
02
Chemistry rules
Every block of class is designed to fire one of the four molecules. Nothing's random.
03
Rhythm is law
You ride to the beat. The music pushes you further than you'd go alone.
This is what a Tuesday looks like.
