ZTrainer

ZTrainer is your training partner for Self Defense Studios curriculum. It helps you learn — and actually remember — every technique from White Belt all the way to Black Belt, using proven spaced-repetition practice.

WHY ZTRAINER

Belt curriculums are huge. It's easy to drill this week's material and quietly forget everything from three belts ago. ZTrainer builds you a short, focused practice queue every day, mixing new techniques with older ones that are due for review — so nothing slips away before your next test.

DAILY PRACTICE, DONE RIGHT

• A fresh 5-technique queue each day, drawn only from what you've learned

• Automatically balances forms, strikes, defensive techniques, and kicks

• Prioritizes new material first, then resurfaces techniques based on how hard you found them last time

• Log your reps and how each one felt — the app adapts from there

• Bonus and extra-training modes for when you want to drill more

TRACK YOUR JOURNEY

• The full curriculum, White Belt through Black Belt degrees

• Mark techniques as learned and watch your belt progress fill in

• Build daily streaks and see your practice history at a glance
