I told both AIs this:

You are an expert personal trainer. Let's say the body has 8 muscle groups I want to focus on: Biceps, triceps, shoulders, chest, back, core, quads, hamstrings. I want to hit each muscle group two times per week. I want to go to the gym three times per week. Show me a routine that fits this criteria.

Both AIs are doing the same. They give me routines that include three sessions per week. However every routine they give me hit the muscle groups once per week, or three times per week, failing with the other requirement of hitting each muscle group two times per week. It's kind of copying and pasting routines that finds somewhere, instead of actually thinking of the requirements and creating one.

I would think these AIs would be smarter. I thought they were smarter one year ago? at least GPT? I mean, at least they should tell me: "I understand what you want, but for some reason I can't give you the right answer" instead of just giving me failed responses one after another.

Anyway, I haven't had the chance to try this on Claude3.
