Sore muscles

Pretty much every Sunday I am sore from body conditioning and abs/core class on Saturdays.
In class yesterday Jennifer had us do squats and lunges–but not as many and much slower. She said we would feel it today and she was right. My butt is so freakin’ sore today. We use that crazy bosu ball so we are also working on balance–which I pretty much suck at.
I was planning on going to the gym today, which is my off day. But I didn’t go to the gym on Thursday or Friday because I had my flu shot. According to the nurse who gives us the flu shots at work that you should let your body take it easy for a couple of days . So I did take it easy–I don’t need to be getting sick right now with work just too crazy.
But then when I woke up this morning I was sore and the last thing I wanted to do was go to the gym. I have been super lazy today. Sundays is my kinda rest day from the gym and I try to make it a rest day from anything else, too.
