Gym software
Your gym's training layer: staff programs with AI, members train with the routine on their phone, and you see what happens between sessions.
Short answer.
Kaizer is the training software a gym's coaching staff uses: each coach builds routines by hand or with AI on 1,500+ exercises, members follow them in the app with videos and set-by-set logging, and loads adjust after every logged session. Kaizer covers programming and follow-up, not gym administration: access control, membership dues and class booking stay in the system you already run. It is used by 1,200+ trainers across 20+ countries, with a free plan to try it with up to 3 members.

When Kaizer is a fit for a gym.
Your management system charges dues and controls the door, but knows nothing about what a member actually trains.
Every coach programs in their own spreadsheet, and none of it stays with the gym when they leave.
You sell personalized training as a separate service and deliver it over WhatsApp today.
You want members to have an app with their routine, videos and progress, without building one.
You need to see adherence and drop-off per member before they cancel.
What Kaizer gives a gym today.
One coach, many members
Each coach on staff runs their book from one panel: routines, history, notes and injuries for every member in one place.
Programming by hand or with AI
AI drafts the first version from goals, equipment and limitations across 1,500+ exercises with video, and the coach adjusts it before publishing.
Automatic load progression
After each logged session Kaizer recalculates estimated 1RM from sets, reps and RIR and proposes the next load. The coach approves.
An app for your members
Members train with the routine on their phone, on iOS and Android, with a video per exercise and set-by-set logging.
Drop-off alerts
Kaizer flags the member who stopped logging sessions, so staff calls them before the cancellation reaches the front desk.
Metrics per coach and per member
Retention, adherence, sessions and PRs, trended against the previous period, so you can see which coach holds their book.
Frequently asked questions
No. Kaizer is the training layer and runs alongside your current system. Access control, membership dues, class booking and the member roster stay where they are. What Kaizer solves is what that system never looks at: what each member trains, whether they are doing it, and how they progress.
Not today. Kaizer's organization layer for gyms, with locations, staff, classes and bookings, is in development and cannot be purchased yet. If that is what you need right now, it is worth talking before you try the product, so you know exactly what you will find.
Today it is bought per coach, on the same plans as an independent professional: Free at USD 0 for up to 3 clients, Starter at USD 19/mo up to 15, Pro at USD 49/mo up to 50 and Unlimited at USD 149/mo up to 500. Flat per-organization billing arrives with the gym layer. For a multi-coach staff, book a demo and we will size it with you.
Yes, they use the Kaizer app on iOS or Android, where they see their routine, a video per exercise and their history. The app is available in Spanish, English and Portuguese.
Routines, history and notes for every member stay in Kaizer, not in the coach's personal spreadsheet. That is a good part of the argument: the programming work stops walking out the door with the person who did it.
No. Kaizer is training and programming: routines, load progression and follow-up. Nutrition is out of the product's scope.
