Examples: Freeletics, Fitbod, Centr AI, Nike Training Club

• Potential for improper form detection (unless paired with camera/sensor)
• Can feel impersonal or robotic

Choosing the Right Fitness Coach: AI or Human?

Choose an AI Coach if:

• You are self-motivated and disciplined
• You need flexibility and on-demand access
• You already track performance with a smartwatch or fitness tracker

Choose a Human Trainer if:

• You are new to fitness and need guidance
• You need accountability and personalized attention
