Forgets nothing.

Unlike ChatGPT, your Massive coach has persistent memory. It knows your PRs, your injury history, what you ate yesterday, and how well you slept. Ask it anything.

✓ Proactive coaching — it messages you, you don't chase it
✓ Reads your Apple Health, Renpho scale, and food logs automatically

Should I train legs today? I'm a bit tired.
Your HRV this morning was 12% below baseline and you trained legs 48 hours ago. I'd push it to tomorrow. Tonight I'd suggest a 20-min upper body accessory session — light pull work, nothing taxing. Your sleep was also only 5.8h.
What should I eat to hit my protein today?
You're at 94g protein so far. You need 66g more. Easiest hit: 200g chicken breast (44g) + 300g Greek yoghurt (30g) = done. You've got 640 calories left to spend.

Be first.
Train smarter.
