Excessive exercise can lead to muscle dissolution. These dissolved muscles will enter the blood and then enter the kidneys through the blood. Myosin will block the renal tubules, hinder the normal operation of the kidney, and eventually lead to kidney damage, resulting in symptoms of acute renal failure.

And kidney damage will keep you out of the gym.
