TL;DR
What did u/Maleficent-Season713 use ChatGPT for?
Someone who couldn't find a ready-made plan for their goals gave ChatGPT their weight, daily routine, usual meals and goals, followed the plan for five months while tweaking it, and says it changed their life. Others in the thread use it for running and marathon training. After five months they say ChatGPT genuinely changed their life and confidence, and that they'd now call themselves shredded. A commenter used it to train through a half marathon and a marathon, feeding back runs and nutrition as they went.
What they did
They entered their weight, daily routine, what they typically eat and their calisthenics and aesthetics goals, and had ChatGPT put together a plan. They followed it for five months, tweaking spots as they learned which exercises worked better. When they noticed it leaning toward making workouts easier, they told it to be stricter while staying encouraging.
How it went
After five months they say ChatGPT genuinely changed their life and confidence, and that they'd now call themselves shredded. A commenter used it to train through a half marathon and a marathon, feeding back runs and nutrition as they went.
Worth knowing
- It only works well with a lot of context, they and other commenters say. Both the poster and the marathon runner found it went easy on them, and the runner suffered for it in the marathon. One commenter said to stay critical of what it suggests. Check with a professional if you have injuries or health conditions.

My goal: [goal, e.g. calisthenics strength and a leaner look] in [time frame]. Equipment: [gym / home / none].
