I hope you used yesterday to recover from the first workout of Phase 2, because it's time to get back in the gym and work again.
The warm-up is the same every day in Phase 2, so it won't seem quite so foreign to you today. Each time you complete the warm-up exercises, you'll perform them a little better. I highly recommend that you go through the warm-up every day. Doing so will reduce the chance of injury and prepare your body for better workouts.
If you need a refresher, refer back to the Phase 2 workout video as often as necessary.
