There's a tool called 'Olympic Squares' that checks athletes in five areas—like how they're performing, how stressed they are, and how well they're eating and recovering—to help figure out if they're overtrained when their performance drops for a long time.

Nine simple check-ins about mood, eating, and how you're feeling during workouts can tell if a male athlete is overtrained — no blood tests or fancy machines needed.

For male athletes who train hard, checking a mix of things like mood, diet, body fat, and hormone reactions might be a better way to spot overtraining than just looking at one blood test.

If athletes push themselves too hard for too long without enough rest, they can develop a serious condition called overtraining syndrome, where their performance gets worse and just won't improve — even after taking time off.
