Personal trainer app: AI coach or a real coach in your phone?

From $0 to $199 a month. What an app-based personal trainer actually does, the AI and human options, and how to choose.

Short answer

Personal trainer apps come in two kinds. AI coaches plan your training and adjust your weights for $0 to $50 a month: GymAdapt (free tier; Pro $24.99/year; our app, iPhone only), Fitbod ($95.99/year) and Dr. Muscle ($49.99/month). Real coaches in an app cost much more: Future is about $199/month for a 1:1 coach, Caliber 1:1 coaching from about $200/month, and Ladder $29.99/month for coach-led group programs.

AN AI TRAINER, FREE TO START (OUR APP)

GymAdapt: plans, adjusts and answers your questions

GymAdapt writes your plan, picks your weights from what you log, and has a coach you can message: "my shoulder hurts on bench", "only 30 minutes today", "swap squats for something else". It changes the workout for today or for good. Free to start; code TRYFREE01 gives a month of Pro free.

A good personal trainer does four things: writes a plan for you, teaches the movements, adjusts as you progress, and keeps you accountable. Apps can now do most of that. The question is which parts you need a human for, and what that is worth to you.
