Build muscle with an AI coach that learns what your body responds best to. myoxin uses your workouts, recovery, progress, and scientific literature to help you train smarter, get stronger, and stop guessing what to change next. Log workouts. Ask training questions. Get weekly analysis and statistics. Let your plan adapt. All in the app, and on WhatsApp too if you prefer. What myoxin does: • A plan that explains its reasoning Every session comes with its why: what your coach changed since last time, and what it is responding to. Clear progression you can follow, not a random AI-generated workout. • Full weekly training analysis myoxin analyzes your workouts, volume, intensity, muscle stimulus, progression, fatigue, and recovery patterns to show what is working, what is stalling, and what should change next. Every Sunday it reviews the week you actually trained and writes the changes straight into next week's sessions, so the analysis becomes a plan instead of a report. The more you train, the more specific the feedback becomes. • AI fitness coach in the app or on WhatsApp Text it. Send voice notes, photos, and videos. Ask what to do in a crowded gym, send a lift video for form feedback, share a restaurant menu for nutrition advice, or send a photo of a terrible hotel gym and get a replacement workout. • 35M+ scientific papers on demand Ask questions about hypertrophy, strength training, recovery, nutrition, soreness, deloads, exercise selection, or programming, with answers grounded in scientific literature and your own training data. • Biology-based muscle stimulus model myoxin tracks how much useful training stimulus each muscle is getting, so you can see which muscles are undertrained, which are progressing, and where you may be adding volume without much return. • Wearable and recovery data integration Connect health and wearable data like sleep, HRV, activity, nutrition, recovery, and body metrics, so your training plan can respond to more than just sets and reps. • Free by design No myoxin subscription. Connect your own Google Gemini API key and your coach runs on it. Disconnect any time. Features: • Fast workout logging built for between sets • Strength training, bodybuilding, hypertrophy, cardio, and gym workout tracking • Set, rep, weight, RIR, warmup, drop set, and failure set logging • Reusable workout templates • Weekly workout split planning • AI workout planner and adaptive training recommendations • Exercise progress charts • Estimated 1RM, tonnage, sets, reps, and trend tracking • Muscle stimulus analytics and muscle heatmap • Custom exercises and favorite exercises • Exercise library for strength, cardio, and mobility • Health and wearable data sync • Track diet, protein, supplements, stress, illness, and alcohol alongside training • AI personal trainer support through text, voice, photos, and videos • Science-backed fitness, nutrition, recovery, and training answers Most workout trackers only record what you did. Most AI fitness apps give generic answers. myoxin is built to close the loop: train, analyze, learn, adapt, repeat. Less random workout generator. Less generic chatbot with gym vocabulary. More like a personal exercise scientist that actually knows your training. Download myoxin and start training with a plan that adapts.
