Hey, there, icedpete. Welcome to T-Nation. It’s your first post, I see!
I’m currently doing ABBH. At the end of the 23 days, I’m going to flip-flop the sets and reps for the given exercises (i.e., change 10x3 @ 80% to 5x10 @ 60%). From there it’s gonna be ABBH II.
In answer to your question, you could start your routine on a Tuesday and get in 6 every-other-day workouts; i.e., Tu, Th, Sa, Mo, We, Fr. Considering all of my/your options at that point, I’d be inclined to take Sa, Su and Mo off, picking back up on Tuesday for another 6 every-other-day workouts, which would finish off a normal 23-day ABBH cycle.
Chad will probably stop by and may have a better answer.
Enjoy the program!!!
