I let AI handle my workout routine... ChatGPT beats Siri AI

In a comparison of a 45-minute, dumbbell-based 3-day full-body routine for a 36-year-old man, ChatGPT was judged to be more structured and long-term focused than Siri AI.

Siri AI offered a basic split with sets and reps, while ChatGPT added warm-ups, weekly structure, recovery, nutrition, and progression principles.

The case shows how practical AI chatbots can be for fitness planning, with ChatGPT delivering the stronger result for now.

It also highlights a shared limitation: neither service yet matches the level of detailed personalization or expert coaching a human trainer can provide.
