ELI5: How does lack of good sleep affect physical performance (weightlifting, running, etc.)?
gpt
when you lift weights, in order for you muscle to grow you make micro tears in the muscle tissue, when you go to sleep you body will fix the tears by increasing the thickness basically so you get bigger muscles. for the optimal results of recovery your body needs food, hydration and sleep so if youre not getting enough quality sleep your body cant repair itself and you can get infured or just stay sore.
