You want to be as rested as possible before your heaviest day.
Also, while building strength on linear progression these is little reason to also start increasing volume or frequency. Rest. There is a lot happening. Workout intensity is increasing each week. Your muscles, CNS, joints tendons and ligaments are all adapting to demands. There are many levels of recovery taking place.
The program becomes more difficult each week. It is in your best interest to maximize recovery while milking linear progressing to help stave off strains, pains and fatigue. It makes the most sense to be the most recovered prior to your heaviest day of the week.
At one point early in my life I made the mistake of increasing frequency and trying to push progression too quickly. I threw out my back and strained my shoulders.
Take this time to listen to your body, so when you may need to increase frequency you are better tuned in to your body.
You can add a lot of strength very quickly with these types of programs. Enjoy the weekends.
