I just finished week 1 day 2. My son (10) is my motivation. I used to be athletic, now my nickname is BBFD, big bad fat dad. Never really bothered me, but as my kids get bigger unfortunately so am I. He said he would do this with me, but dang it boy, can't you tell I can't breath, much less talk! I need to complete this. I owe my kids that much, to remain a SUPER HERO!
