About
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. Start with the Novicio pillar: choosing your gear, wrapping your hands, stance and guard, breathing, vocabulary, footwork, attack and defense. Finish all 12 videos and earn your first medal.
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. The app calls out each combo by voice and shows every punch on screen while you train.
PHYSICAL (FÍSICO)
Seven guided workouts, with every exercise on video and a timer: Prende la chispa, Coraza, Recluta, Instinto Salvaje, Tambor de Guerra, Blindaje and Soldado. Build strength, endurance, core and mobility, at beginner and intermediate levels.
YOUR PROGRESS
Your streak counts the days you train. Your profile keeps your sessions, medals and combos.
Create your account with email, Apple or Google. You can delete it anytime from your profile.
No more excuses. Download Cronos and throw your first round.
