Sometimes after I do lunges or squats my knees hurt and feel weak. Does this happen to everyone or is itmy joints? I hope it's not my joints because I am only 14 and I started working out last week.
For example. Yesterday I did lunges. Today my left knee feels weird. It doesnt quite hurt, but it feels weak compared to my right leg. And when i run it hurts a little bit. I dont think I injured myself beacuse I can still walk fine. There isnt really much pain. But it just seems a little different than it used to be.
Does this happen to everybody? Could it be I am using bad form on lunges? Any help or suggestions will be appreciated.
