AI or human trainer?

AI is always available and good at everyday questions. A human trainer can watch you move, knows you and keeps you accountable. In TrainersBook you do not have to pick forever: you can start with an AI trainer and connect with a personal trainer later. Unsure? Read is a personal trainer worth it?

Good to know

AI can make mistakes and does not replace medical care. You choose whether you agree to AI features, and you can change that under Privacy & Data.

Common questions

Can an AI replace a personal trainer?

For everyday questions and planning, AI can help a lot. It cannot watch you train in person or know you the way a good trainer does. Many people will get the most from combining both.

Which languages does FitAI speak?

English, Swedish, Norwegian, Danish, Finnish, German, Spanish, French, Dutch and Polish.
