When i first set up my c4s i posted a video of me going up the stairs in my house (now my sisters) and having a tough time getting through the door. It was tough then, now its nearly impossible!!! Watch as a crack almost every stair on the way up the as i try to go through the door i accidentally break the hinge! But shhh don't tell anyone! I walk up and down the stairs for you so you can see how i fill the entire stairway. I'm at my highest weight ever! Weigh in coming soon!
