Hi, maybe you guys can help me... Well I have my client doing shoulder width squats and for some reason, I hear alot of weird sounds emanating from her knees as she goes up and down. So I had her try taking a wider stance, and I always tell her to keep her knees pointed outward along with her toes, and to never wobble her knees. Her form seems to be decent, but still I hear those sounds! What could she be possible doing wrong?? I mean I don't want to injure the poor lady...Any suggestions??
