Gainr: AI Personal Trainer

Gainr: AI personal trainer. Your AI coach. Your plan. Your progress.

Meet Gainr, the AI fitness coach that replaces guesswork and goes beyond a workout builder.

Instead of asking you to piece together your own training, Gainr acts like a real coach. It builds your week, tells you what to do next, adapts when life changes, and helps you stay progressing over time.

Whether you want to build muscle, get stronger, lose weight, or just train more consistently, Gainr gives you a plan designed around your goals, schedule, equipment, and workout history.

What Gainr Does

AI Coach, Not Just a Workout Generator
Gainr creates your training plan for you. Open the app and see exactly what your next assignment is. No more wondering what to train, when to train, or how to structure your week.

Adaptive Weekly Planning
Your plan is built around your fitness level, goals, preferred training days, available equipment, session length, and real workout history. As you train, Gainr adjusts.

Coach-Led Adjustments
Need a shorter workout? Want to make it harder? Missed a session? Just ask. Gainr can update your plan, rebuild workouts, and rework the rest of your week when needed.

Personalized Workout Recommendations
Every assigned workout is tailored to you. Gainr uses your profile, training data, and recent sessions to generate workouts that feel relevant, progressive, and specific.

Track Real Progress
Log workouts, complete sets, and watch your progress build over time. See personal records, volume trends, completed sessions, and the metrics that actually matter.

Built-In Coach Chat
Ask Gainr why a workout is on your plan, how to adjust your week, what to do if you missed a day, or how training is going. It’s not just a chatbot. It’s connected to your actual plan and history.

Flexible Training Tools
Want more control sometimes? You can still create one-off workouts, build programs, browse exercises, and mix manual training with AI coaching when you want to.

Exercise Library
Access a large exercise library organized by muscle group and training type, with descriptions to help guide your training.

Works Across Devices
Train on your phone, tablet, or computer. Your workouts, plan, and progress stay in sync.
