Today calls for the last resistance workout of the first microcycle, so make sure it's a good one! Remember that each microcycle has a very specific purpose. This first microcycle was built to introduce you to the program and to show your body how it's expected to perform. Trust me: It only gets harder and more fun from here on out.
You have a rest day tomorrow. Put everything you have into today's training, lift with unflagging focus and determination, and then enjoy the rest of your day. After all, you grow outside the gym with adequate rest and proper nutrition.
