What changes on 4th week?

So, as the 3rd week raps up I am going to have a different routine next week. The routine for BLS is as follows:

3 regular weeks

strength week A

3 regular weeks

strength week b

deload/rest week

Next week will be strength week A, so what changes? Instead of 5 days a week, I drop to 3. Here is what week 4 will look like.
