Cronos is the training app of Cronos Academy, a network of combat sports gyms in Paraguay. Learn boxing from scratch with videos by head coach Lehi Leiva, practice combos with a voice that calls them out, and train your body with guided workouts. The app is in Spanish. THEORY (TEORÍA) A path of short videos that unlock one at a time.

HEAVY BAG (SACO) Build combos with a 12-punch calculator (jab, cross, hooks and uppercuts, each also to the body), pick your pace, place your phone about two meters from the bag and start.
