Your AI Coach

A COACH THAT
KNOWS YOUR
HISTORY

Not a generic chatbot. Your coach has access to your profile, body scan, workout logs, and meal plan — so every answer is personalized.

Ask about nutrition, form tips, rest day routines, or how to modify exercises around an injury. Like texting a trainer who actually remembers you.

What should I eat before my workout tomorrow?
🔥
Based on your 7AM upper body session, eat 90 minutes before:

• Greek yogurt with berries and granola
• Or banana with almond butter on toast

Aim for ~300 cal with 2:1 carb-to-protein ratio. You hit a bench PR last week — let's fuel another one! 💪
My left shoulder is sore. Should I still train?
🔥
Since you flagged shoulder sensitivity, let's swap overhead press for landmine press — same muscles, less joint stress. If it's sharp pain though, take the rest day. Your streak won't break for recovery!
