I usually go heavy >85% both days. Every 3rd Week or so I will throw in the max reps/failure on the 2nd day and sometimes keep it for 2 weeks straight. As far as Deloading I do it when I start feeling aches and pains which is usually anywhere from 4-6 weeks. But I may just use it to deload my “pressing muscles” and keep the pulls heavy. If I’m feeling like total shit and my mood and sleep sucks then I know its my CNS and I need to deload everything. I do so much pressing with the bar and it takes in excess of an so all I’m left with for accessory work is sometimes DB Presses, high rep delt work, and some skullcrushers.
