After getting home from get off work or school, I immediately sit cross-legged on the sofa, with snacks in one hand and an iced cola in the other, watching my phone and watching TV, looking very happy.

Due to the effect of gravity, the knee joints will bear the force of sinking, resulting in uneven force on the inside and outside. Over time, the knee joints are also prone to deformation. So, don't sit cross-legged anymore. While hurting your knees, be careful not to make your legs look ugly.

Knee injury action three:Long time squatting

Do you squat while browsing your phone and relaxing, and then 10 minutes pass and you are still squatting? Do you know that squatting is actually an advanced version of deep squatting? Especially when the squatting posture is greater than 90 degrees, the compression on the inner knee joint will increase, causing wear on the inner side of the patella. So when you go to squat, try to put down your phone and control the whole process within 3 minutes.
