myoxin: AI Workout Planner
Stop Guessing & Build Muscle.
Free
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.

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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Your watch and your log are one workout. When your watch or ring records a session you also logged, it now shows once, with
the device's heart rate and calories on that workout. Link or unlink a recording yourself, and your choice sticks.
Check your form from the workout. Tap an exercise, pick a video or photo, and the coach reviews it.
The research behind your plan. The studies the coach drew on are listed under your plan, so you can see why a session looks
the way it does. Completed sessions are now named for what you actually did, not what was planned.
Estimated 1-rep max, done properly. One trend per lift, RIR counted everywhere, bodyweight lifts counted at their real load.
A lift with too few sessions shows no trend instead of a misleading 0%.
Your schedule keeps going. Sessions are extended automatically. If the horizon ever does run out, the app says so instead of
showing a rest day.
Routines in the order you train them. The routines list follows your week. A routine you train twice appears once, with both
days on it.
Coach chat stays put. Long answers no longer jump the scroll, the keyboard no longer covers what you're typing, there's a
Done key, and an unread dot on the Coach tab tells you when a reply is waiting.
Honest about Health access. If you revoke myoxin's permissions in Settings, the app tells you instead of claiming it's still
connected.
Fixes. Several iOS freezes when moving between sheets (removing an exercise, creating a custom exercise, filters, supersets,
warmups). A custom exercise you create is now added to the routine straight away. The warmup generator's keyboard can be
dismissed and no longer covers the fields. Optional crash and freeze reporting, only if you opt in, so we can find the next
one faster.
