Whole New Routine at the Gym

In December I was just starting to feel like I was "getting it."  Today, a whole new routine!  Says she changes it up every 3 months so I was back in spasticville today.  Feel so totally uncoordinated when I go there!  Good workout though - what I could do of it.  Part of my problem is that I can't hear and understand a word she is saying.  Music is loud and without the hearing aids I don't get anything that she says.  So I can't follow instructions because I don't know what they are.  I just have to watch and try to copy.  I'll go again next week though because I think it's a good change up from running every day.
