The relationship between squat and knee injury
Squats of different amplitudes will exercise different muscles. Standard squats can exercise all the muscles of the lower body. When the squat moves to the lowest point, the back of the thigh will be close to the calf, and your body will no longer be able to lower. At this time, you need to work together with your thighs and knees to push your body up until your legs are completely straight. No matter how small the motion range is, it is not considered "full range".
Some people think that squatting directly to the lowest point is not good for the knees, but this is not the case. 50 weight exercise exercises with bare hands
