Currently this is the routine I have been running:
my work is divided into 12 90-minute sessions. So I encorporate 2 subs in between a single sessions
In the First 3 session, I play Spartan and limitless(or limitless x depending what I am learning)
From the 4th session till the 10th session I switch to khan st3(and limitless)
10th to 12th I go back to spartan.
I listen to beyond limitless eighter after every alternate session or whenever I feel like I need more brain power.
5 loops of spartan
7loops of khan ST3
12loops of limitless
