AI workout planner for coaches
Plan every client's week in one view — and let load progression maintain itself.
Short answer.
Kaizer works as an AI workout planner for coaches: you build each client's programming in the routine builder, the AI drafts the routine from goals and equipment, and after every logged session it recalculates loads using estimated 1RM from NSCA-derived tables. Programming stops being a static document and becomes a living plan that progresses on its own, client by client.

When AI planning makes sense.
Your programming lives in spreadsheets that go stale a week after you build them.
You program well, but keeping 20-30 clients' progressions current doesn't scale.
You want to design the structure yourself and delegate load recalculation to the AI.
You need to see at a glance which client has a current plan and who's run out.
You want to adjust programming with real session data, not gut feel.
Planning in Kaizer.
Routine builder
Structure days, blocks and exercises over a base of 1500+ exercises; everything editable, with or without AI.
AI draft
The AI drafts the routine from goals, preferences, limitations and equipment; you fine-tune it.
Automatic progression
After every logged session it recalculates loads using estimated 1RM from NSCA-derived tables (sets, reps, RIR).
Per-client assignment
Each plan is assigned to its client and lands in their app; you see who has a current routine and who doesn't.
Session data
Adherence, loads and PRs per client feed your next programming decision.
Built-in assistant
Ask for plan changes in natural language, by text or voice, and the assistant executes them.
Frequently asked questions
You stay in control. The AI drafts routines and recalculates loads, but structure, exercise selection and the final call are yours — everything is editable in the builder.
With every session a client logs, it estimates 1RM using NSCA-derived tables and adjusts sets, reps and loads based on the logged RIR.
Yes. The builder works fully by hand: you set up days, blocks and exercises yourself. The AI is optional help, not a requirement.
From 3 clients (Free plan) to 500 (Unlimited). The plans in between cover 15 and 50 clients, with annual discounts and local pricing per country.
Progression only uses logged sessions, and Kaizer's alerts tell you when a client stops training so you can step in early.
