How I ACTUALLY Built an AI Coaching App That Analyses Your Training Like a Pro

Описание: I built an AI-powered coaching app from scratch while juggling two jobs, parenting, and training for elite marathons. In this video, I take you behind the scenes of how I created Lactate Training, an app that combines blood lactate science with AI to give you personalised, pro-level session feedback.
I reveal why I chose Google’s Gemini over ChatGPT and other AI models for powering the LT fitness app. As a father of two with a full-time job and limited time to train, I needed an AI that could truly understand and analyze performance data and Gemini delivered.

From heart rate zones to core temperature, cadence, and ground contact time, the LT app uses advanced AI prompts to give you personalized coaching feedback. Whether you're training for a marathon or just want to get in shape without sacrificing your lifestyle, this app is designed to help you run smarter, not harder.

You'll learn:
Why I started the project
How I trained the AI to understand real human training data
The challenges of building a coaching app for everyday and elite athletes
What makes this different from generic 12-week plans or just “winging it”
A sneak peek at the app in action

If you're curious about AI, coaching, or the future of personalised training this one's for you.
