Hi FitNut,
I am changing up my routine a bit and do this for BLF:
M - GS Back, Shoulders, Bis
T - Imax 3 intervals 1-5
W - GS Legs
TH - Imax 3 intervals 6-10
F - GS Chest, Triceps
S - LowMax (I know this is longer than the 30 minutes but it is a good workout, I was dying last weekend)
This is just something I am going to do to change up a bit from the pyramid workouts and see how it works. I am in week 7 of BFL.
