You don't lack tools — you lack decisions
Why do "general AI tools" seem convenient but actually lead to wasted training?
General AI tools are not coaches.
They just answer whatever you ask.
So you need to learn to be your own coach first to ask the right questions.

Hsu Kuo Feng x AI
Data Preparation
You organize your own dataTons of watch metrics to sort through. If you don't know what's important, you're feeding garbage.
Just use RQ to record your data — Hsu Kuo Feng x AI reads and interprets it automatically.
Feedback Quality
You have to know how to ask (and follow up)Vague questions get safe, generic answers. Wrong questions get answers that go along with your mistakes.
No need to ask! Hsu Kuo Feng x AI directly analyzes your data and journal to identify issues and give feedback.
Memory
No memory = starts from zero every timeDoesn't know last week's fatigue, recent tightness, or regression trends. Most dangerous during race prep: not knowing when to back off or push.
Memory feature coming in future update! All past RQ data will be evaluated together for comprehensive assessment.
Training Logic
No unified training logic = different advice every dayWon't maintain periodization consistency or treat stimulus-recovery-accumulation as one continuous thread.
Hsu Kuo Feng's 20 years of unified endurance training logic, built on 300,000 words of real coaching feedback and 10 years of training data.
General AI isn't dumb — but it's not a "coaching system"!
Hsu Kuo Feng x AI: You don't need to learn to be a coach to still get elite endurance coaching feedback, training analysis, and injury prevention alerts.
Hsu Kuo Feng x AI is not here to make running fun — it's here to prevent reckless training, wasted effort, and injuries!
Helping you understand yourself better through the training process!
It will:
Tell you when to back off — won't let you push through recklessly
Tell you when you can push harder — not always conservative
Point out strength and technique gaps you've been ignoring
Use consistent logic to track whether you're backsliding over time
✅ Best for:
Runners who want to improve, worry about injury, and are willing to write simple training journals
❌ Not for:
Runners who only want encouragement and don't want to adjust their training
Completely different. General AI has no unified training logic. This feedback system is built on Hsu Kuo Feng's coaching judgment framework — consistent logic, and future updates will add memory to track your condition over time.
