AI is good when it comes to nutrition and physical therapy programs. It falls short at higher level training knowledge (which you wouldn’t be able to get from /fit/ anyway) and /fit/ greentexts.
At this point, /fit/ is only good for funny green texts stories. Pic related, I asked Grok to write a green text story about walking into the women’s locker room at the gym. Completely devoid of humor. Computer niggers will never replace us.
