-  1.  Is it normal that my knees sound like popcorn when I squat?My knees make a little crackle on the way down, especially after sitting a while. It doesn't hurt, but it sounds like a snack bar opened under my skin. Is this just air and age, or a sign my form or mobility needs work?Posted 2 months ago by Paul Reyes
