What they did
Both AIs produced three-day-a-week workouts, and a physical education professional and a personal trainer pointed out what worked and what didn't.
How it went
The weight-loss workout included, for example, burpees and jump squats for someone who may be a beginner, the kind of thing the professionals criticize. The account gives no numbers.
Good to know
Use the AI's workout as a starting point and have a professional (CREF) validate the load and technique.
The prompt
I am a beginner, [age], [limitations]. Build a 3-day-a-week workout using only [equipment], with easier versions of each exercise and how to tell if I'm doing it correctly.
Replace what is in [brackets]. Prompt written by us from the account, not a literal copy of the source. Do not paste other people’s personal data (privacy laws such as LGPD and GDPR apply).
