Chest & Shoulder Specialization

Hello, I am doing Chad Waterbury’s 10/10 Routine which is off the chain and making great progress, afterwards I wanted to a 3 week specialization focusing on my Upper Chest and Shoulders so that aesthetically I will look nice and balanced.

What would you guys recommend for this as I am trying to do it in a HFT format using 5 days a week training which I think should do the trick but I don’t want to burn out or injure myself.
