Ok- i have measured my arms for the fun of it more than once. Meaning to do a full body measure and pictures (but been to lazy to get around to it). I could of sworn i had 14 1/2" arms. I have only been on my first lifting cycle, using WBB#1 for 5 weeks. I picked up the tape for the heck of it this morning and its around 16". I just dont think its possible, is it? Maybe they were 15 1/2. But i swore not! I havent stayed as true to my diet as i'd like so i know im eating enough cal to gain. Also been using creatine for last 2 weeks i'd guesss. I have followed the program and havent missed any days yet! also added some extra bi and tri in (just one extra set) cause i didnt get sore at all like the rest of my body does after a workout. thanks for any ideas.
