AI app for personal trainers
An AI that builds routines, adapts loads and operates the platform for you — not a chatbot bolted on the side.
Short answer.
Kaizer is an AI app for personal trainers that lets you create routines, track clients and grow your business from a single platform. The AI builds routines from goals and equipment, adapts loads after every logged session, detects churn signals and generates business insights. It also includes a built-in assistant that operates the whole platform in natural language, by text or voice.

When an AI app makes sense.
You've tried coaching apps where 'AI' was just a chatbot that never touched your programming.
You want your clients' loads to adjust after every session — not at the end of the month.
You'd rather ask for things in plain words, by text or voice, than dig through menus.
You need something watching your clients' adherence while you're on the gym floor.
You want business decisions backed by data without building the reports yourself.
What Kaizer's AI does.
Routine creation
Generates routines from goals, preferences, limitations and equipment, over a base of 1500+ exercises.
Load adaptation
After every logged session it recalculates loads using estimated 1RM from NSCA-derived tables (sets, reps, RIR).
Churn detection
Flags risk and drop-off signals per client so you can step in early.
Business insights
Generates retention, adherence and session readings that tell you where to look.
Built-in assistant
A ChatGPT-style assistant inside Kaizer that operates the platform in natural language, by text or voice, and executes actions for you.
Frequently asked questions
Kaizer's assistant doesn't just answer — it operates the platform. It searches, builds and edits routines and executes actions in natural language, by text or voice. Beyond the assistant, the AI works on its own: it adapts loads after every session and detects churn signals.
No. The AI proposes and automates the repetitive parts — initial routines, load adjustments, alerts — but you review and decide. Programming judgment stays yours.
After each session a client logs, it estimates 1RM using NSCA-derived tables and adjusts sets, reps and loads based on the logged RIR.
There's a Free plan for up to 3 clients. Paid plans run from USD 19/mo (Starter, up to 15 clients) to USD 149/mo (Unlimited, up to 500), with annual discounts and local pricing per country.
