About

Kettlebell Coach Pro

Read full description

Train with kettlebells the right way. Kettlebell Only gives you proven programs from the best coaches in the world — Pavel Tsatsouline, Dan John, and Valery Fedorenko — built into a clean, focused app that stays out of your way during workouts. REAL PROGRAMS, NOT RANDOM WORKOUTS Every program in the app comes from published, battle-tested methodology: - Simple & Sinister (Pavel) — The gold standard beginner program - Rite of Passage (Pavel) — Structured pressing progression - Armor Building Complex (Dan John) — Efficient full-body training - 10,000 Swing Challenge (Dan John) — The ultimate endurance test - Long Cycle (Fedorenko) — Competition-style kettlebell sport - And more, across all difficulty levels DESIGNED FOR DURING THE WORKOUT Big tap targets for sweaty hands. Dark mode workout screen. Timer always visible. One-handed operation. No scrolling, no menus, no distractions — just your current exercise and a big "Done" button. EXERCISE LIBRARY WITH FORM GUIDANCE Browse 30+ kettlebell exercises with animated illustrations showing the actual movement. Each exercise includes: - Primary and secondary muscles worked - Rep ranges for strength, hypertrophy, and endurance - Common mistakes and how to fix them - Technique cues from the source coaches TRACK WHAT MATTERS - Automatic PR detection (max reps, max weight, volume, density) - Consistency rate over streaks — because showing up 3x/week for a year beats a 30-day streak that ends - Training calendar heat map - Volume trends over time CHALLENGES Test yourself with timed challenges like the Secret Service Snatch Test, or commit to multi-week training blocks like the 10,000 Swing Challenge. Track your progress session by session. BUILT ON SCIENCE The app uses implementation intentions (Gollwitzer research) during onboarding to help you build a training habit. The reward system is based on Huberman's dopamine research — you won't get a confetti screen every time, because intermittent reinforcement builds stronger habits than constant praise. PRIVATE BY DESIGN All your data stays on your device. No account required. No analytics. No tracking. No cloud. Just you and the kettlebell.
