Those who squat are not afraid of injury
A person who does 100 squats daily strengthens joints and ligaments. Being trained, they are not subject to sprains and bruises, and if trouble does occur, then its consequences are insignificant.
By the way, it is shallow squats that help get rid of the annoying crunch in the knees and joints. In fact, you can practice deep squats, but you should definitely take into account the fact that they create a large load on the kneecaps, and if your kneecaps are weak, then it’s better not to risk it, at least initially doing shallow, but static squats.
