Ok ladies, sorry for all the questions, but you all are knowledgeable and I'm early (4weeks), so I haven't seen my doc yet. Here's the question: do any of you ever get so involved in your workout that you forget the heart rate a get it a little too high? I teach muscle pump and this Tuesday my HR hit 187. Now, I'm freaking out and afraid to keep exercising because I don't want this to happen again. Any thoughts or similar experiences?
