I cant lift my arms

So I had to restart the p90x, I skipped the second day, and I didn't have the equipment for the 3rd day, so I decided to delay it, then restart it all. So today is the first day, my arms are completely wiped out, I expect to be super sore tomorrow, but it's worth it! I gotta keep it going, so keep track and make sure I keep doing the work. Also I saw a Cop on a segway, that is all, dismissed.
