Legs and Back. This one really woke my legs up from their slumber. I have been feeling this one all day. Anytime I had to bend my legs during the day it reminded me of how much I brought it. Getting in and out of my car became a new challenge. (It wasn’t so bad but I could feel the muscle ‘pain’ all day). Walking up the stairs to my apartment I could feel it. This must mean I did something right. The more muscle ‘pain’ I feel I am sure the better results I will see. The pain is refreshing because I know I really gave it my all and its nice to be reminded of that all day.
