*Boy, did I feel strong this morning and I wonder where it came from. Deads are feeling great, wanted to go heavier but, I didn't want to take the chance popping a rib again(baby steps). Whelp, starting to hear the skinny comments at work already, "You better go back to the break room and get some of that food you are starting to whither away". And what is with the joints already, I'm feeling it in my knees, ankles (especially the one I sprained in 2006) and wrist. Could my body fat be low enough at 17 weeks out to have these issues? Hopefully the joint rescue that I ordered from my sponsor helps.
