Not another workout app. I'm your coach. A real periodised programme, rewritten every week around what you actually did. Let's get strong. Hello, I'm Charles. I build your strength training programme. I'm not another workout app. I'm a coach. I learn how you train, then I write you a real periodised programme. Accumulation, intensification, strength. Each phase builds on the last. Every month, I rewrite the next block based on what you actually did. WHAT YOU GET - Periodised programming. Real macrocycles with accumulation, intensification, and strength blocks that actually progress. Not random workouts. - Pain aware training. If a movement hurts, tell me. I swap it. No pushing through pain. - Equipment aware. Tell me what your gym has. I plan around it. Real exercises for the kit you actually own. - Weekly check ins. I learn what worked and what didn't. Your next week adapts. - Focus lifts. If you have 2+ years of training history, I tune your programme around the lifts you want to improve most. HOW IT WORKS - Assess. Answer about 15 quick questions about your strength, history, equipment, and any injuries. I learn how you train before I programme a single set. - Programme. I build your macrocycle. Phase one unlocks immediately. Future phases unlock as you progress. - Train. Open the app. Follow today's session. Log your sets. Move on with your day. WHO IT'S FOR - Lifters who want a real programme, not a random workout generator. Beginners who want to start right. Intermediates and advanced lifters who want periodisation done properly without the spreadsheet headache. - START WITH 14 DAYS - No payment upfront. Train free for 14 days, cancel any time. After your trial, Charles Pro is $9.99 / month or $79.99 / year. - Subscriptions auto renew unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription in Settings > Apple ID > Subscriptions.
