Software for strength coaches
Periodize in blocks, log every set and let estimated 1RM recalculate itself after each session.
Short answer.
Kaizer is software for strength and powerlifting coaches that handles periodization, set-by-set logging and load progression in one platform. After every logged session it recalculates estimated 1RM using NSCA-derived tables and suggests the next loads; you set the criteria and the system does the repetitive work. Over 1,200 coaches use it across 20+ countries, with a free plan for up to 3 clients.

What Kaizer includes for strength and powerlifting.
1RM recalculated per session
After every logged session, estimated 1RM updates via NSCA-derived tables and the next loads adjust automatically.
Block periodization
Structure mesocycles with the block editor: weeks, sessions and progressions you can duplicate and adjust.
Supersets, circuits and drop sets
Group accessory work into supersets and circuits, and prescribe drop sets with the weight of every drop, which your client sees set by set in the app.
Set-by-set logging
Loads and reps of every set live in the app; the client's history builds itself.
Automatic or manual load management
Choose per client: Kaizer suggests loads automatically, or you keep manual control.
History and PRs per exercise
Every big lift with its trend: best marks, volume and progression without spreadsheets.
Client app
Your clients see the day's session, log every set and message you from the same app.
