## What is Kaizer?

Your trainer already uses Kaizer. This is the app you train in together.

In Kaizer your trainer sends you your routines, follows your progress, adjusts whatever needs adjusting, chats with you, asks for form videos and plenty more. All of it in one place, without leaning on three other apps.

NO TRAINER YET?
Browse the marketplace inside the app. Every profile shows how that coach works, their specialties and whether they train online, in person or both. Subscribe to the one that fits and they are notified the moment you join.

YOUR SESSIONS, IN DETAIL
Sets, reps, load, rest. Supersets, circuits and dropsets when your plan calls for them. Every exercise ships with an illustration of the muscle it works, so you know what you are aiming at before you lift.

ASSISTED PROGRESSION
Week over week, Kaizer writes the loads of your upcoming sessions from what you actually lifted. You always know what to do when you walk into the gym, and the weight on the bar keeps moving.

SMART REPLACE
Machine taken? A movement you cannot do today? Kaizer suggests alternatives that keep the point of the exercise intact, so swapping one leaves the rest of the plan standing.

EVERYTHING IN ONE PLACE
- Direct chat with your trainer: text, photos, files and voice notes
- Full training history, streaks and progress your trainer sees too
- 1,500+ exercises with illustrations
- Apple Health sync and Live Activities while you train
- Rest timer that runs on your lock screen

TRAINING ON YOUR OWN?
You can also use Kaizer without a trainer. Describe what you want in plain language — four days a week, bad knees, dumbbells only — and Kaizer builds a complete structured program in seconds, and keeps adapting it as you log your work.

Kaizer works in Spanish, English and Portuguese, in 20+ countries.
