Day 10 of the Power 90 is out of the way now. I was really tempted to not workout this morning since my knees and calves are hurting a little lately. Had to do some cross walking in place of the bunny hops since those are just too much pressure on the calves today. I am feeling changes happening in a lot of muscles in my body, especially in the abs. Probably not too noticeable yet, but there is a hell of a lot of muscles that are starting to come in to shape slowly.
