A friend of mine was at the gym. She was talking to a trainer and mentioned that her back had been hurting her. The trainer started feeling around on her back, and told her that she had lactic acid knots built up in her back. The trainer massaged on them and worked them out, and her back felt better.
I have never heard of lactic acid knots built up. The trainer said you can feel the person's heartbeat in one of those knots, that's how you locate them.
Am I just uninformed, or is this trainer full of it, and just worked out a sore spot in a muscle?
