Kaizer for Coaches

Read full description

Kaizer Coach is the app for trainers and gyms you want within reach. What you do in the Kaizer dashboard, from your phone: your clients, your members, routines, schedule, payments and chat. YOUR CLIENTS, ORGANISED Your whole roster in one place. Find any client in seconds, open their profile and follow their progress: adherence, completed sessions, streak, weight, goals and weak points. Add private notes so nothing slips. PLANS THAT ADAPT Build reusable programs and assign them to your clients. Organise by weeks and sessions, and write routines with everything you need: sets, reps, load, rest, supersets, circuits and dropsets. Every exercise ships with an illustration of the muscle it works. SESSIONS IN DETAIL Define each movement precisely and leave notes on the whiteboard (warm-up, cues, cool-down) so your client knows exactly what to do. DIRECT CHAT WITH YOUR CLIENTS Talk to each one inside the app: messages, photos, files and voice notes. Keep the follow-up close without leaning on other apps. FOR GYMS If your gym, box or studio runs on Kaizer for Gyms, the app has the same as the dashboard: - The schedule of classes and gym-floor slots, with capacity and bookings - Members' join requests, to accept them from your phone - Payments: who paid, who owes, memberships, enrollment fees and reminders - Each member's profile with their membership and scale data - Shop and register to sell at the front desk - Phone notifications for join requests and last-minute cancellations Kaizer keeps track of payments; it does not process the money. AI ASSISTANT Your coaching copilot. Ask it to draft routines, follow up on clients, look up exercises and explain how your business is doing. Ask it anything, whenever. LET THEM FIND YOU Publish your profile on the Kaizer marketplace: clients who do not have a trainer yet see how you work, your specialties and whether you coach online, in person or both. You can also share your personal link to bring clients in from outside. GROW YOUR BUSINESS Invite people to your list and measure what matters: adherence and retention. EVERYTHING IN ONE PLACE - Home dashboard with your day at a glance - Alerts for clients with no routine assigned - Exercise library with illustrations - Sign in with Apple and Google - Notifications when your clients train or message you Kaizer is built for personal trainers, coaches and fitness professionals who want to spend less time on admin and more time coaching.
