ChallenGYM

**ChallenGYM — Trainer on Duty** The learning and practice app for fitness trainers: 102 strength-training exercises with images, full anatomy breakdowns, execution cues, common mistakes — plus a wizard that builds professional training programs for clients. **■ Training Program Builder** Answer a few questions — level, goal, frequency, workout duration, available equipment, and health declaration — and the wizard builds a complete weekly training program. At every step, it explains the professional reasoning behind the decision and teaches the fundamental training principles: progressive overload, supercompensation, progression, specificity, the FITT principle, and periodization. **Two types of programs:** • **Client Training Program** — a fixed weekly schedule based on the client’s goal, level, and available equipment • **102-Exercise Practice Program** — a weekly rotation covering all 102 exercises to prepare for the exam Programs are built according to training methods commonly used in Israel: Full Body, A/B, A/B/C, Upper/Lower, and Push-Pull-Legs splits; proper exercise order (multi-joint before single-joint, large muscle groups before smaller ones); and appropriate sets, reps, intensity, and rest periods based on the training goal. **■ Five Practice Modes** • **Trainer on Duty** — one round covering each of the 102 exercises • **Identify the Exercise** — every exercise appears once, in random order • **Exercise DNA** — questions about the joint, movement, or prime mover • **Find the Mistake** — identify a common mistake or an incorrect statement • **Full Exam** — 204 questions, exactly two for each exercise **■ Exercise Library** Search and filter by muscle group, with an anatomical DNA table for every exercise — joint, movement, agonist, and synergists — plus execution cues, common mistakes, and an image gallery. **■ Progress Tracking** Points, accuracy percentage, best streak, and mastery level for each training area. No registration is required to use the app. Registration is only needed if you want to save training programs to the cloud and access them from multiple devices.
