KAI Academy · AI Strength Coach

Stop guessing why your training isn’t working.

The lifting academy in your pocket. Trained on your data. Grounded in the science.

KAI sees your last workout. ChatGPT doesn’t.

Why KAI

Three pillars. One coach.

KAI isn’t just a name. It’s how we coach.

Knowledge

Training advice grounded in the actual science of hypertrophy, recovery, and progressive overload. Not bro-science. Not generic templates.

Adaptive

Connect your training data once. KAI reads every set, remembers every PR, and updates your plan as you progress.

Intelligence

An AI coach that thinks with you, not at you. Ask anything. Get answers anchored in your numbers and your goals.

How it works

A coach that actually knows you.

Connect your training data once. From there, KAI works in the background, spotting patterns, answering questions in plain language, and checking in when life gets in the way.

Grounded in your training

Share your Hevy export once. KAI reads every set, every PR, every missed session, and remembers it. No re-explaining what you did last week.

Built around your goals

Bench 100 kg by summer. Sub-2-hour half marathon. Post-injury return. Every reply is anchored to your specific goal — not a generic template.

Checks in on you

Set when KAI reaches out: Sunday night planning, mid-week recalibration, post-workout review. Consistency is the hardest part. KAI handles the nudge.

Features

Less guesswork. More signal.

Conversation

Ask anything about your training

“Why did my squat stall?” “Am I doing too much volume?” KAI pulls the actual numbers from your sessions and answers from there.

Check-ins screen with templates and time scheduling

Scheduled check-ins

Pick a day and time. KAI opens a thread when you said you’d show up.

Sidebar showing coach context, check-ins, and conversation history

Everything in one place

Goals, conversations, and check-ins live one tap away. No dashboards to maintain.

Goals you can edit

Goals change. KAI keeps a living profile so the advice stays current.

Charts when they help

Trends, comparisons, volume across blocks. Rendered inline, not in a dashboard you’ll never open.

Empty chat with example questions to start any conversation

Start anywhere

No menus to learn. Just type what’s on your mind — KAI picks up the thread, every time.

Why KAI exists

I built this because I needed it.

I train four times a week. I want to progress. But I always felt like I wasn’t training optimally, and the plans I’d find online weren’t made for me. Generic blocks, generic templates, no idea how I actually moved last week.

Consistency turned out to be the hardest part. Not the workouts themselves. The showing up, the small recalibrations, the honest conversation with myself about whether what I’m doing is still working.

KAI is the coach I wanted: one that reads my actual training data, remembers what I told it, and pings me on the days I said I’d show up.
