Maybe you’re overestimating your 7RM. You only do three sets of five, so you should have a few in reserve. If anything, you would come close to failure on the last set and last rep. Only three sets of each exercise shouldn’t cause you to fail. The one-minute rest breaks are what help induce hypertrophy. If you take too long, it’ll be a strength routine with little gain in hypertrophy.

I’m not so sure about your muscle biology there Nate… I appreciate your general training knowledge, as evident in other threads. But, while I’m by NO means an expert, from both my studies in exercise physiology and from personal experience, I have to disagree quite strongly.
Hypertrophy can be initialized by many different set, rep, TUT schemes. Longer rest periods allow for more ATP to be synthesized so the next bout can be more productive. Since white fast twitch fibers have the greatest potential for growth and they also require the most readily available energy (stored as ATP energy), decent rest periods will greatly enhance their stimulation. Why are powerlifters so big if the best way to reach hypertrophy is with short rest periods??? I doubt you could find a big and strong powerlifter than takes anything less than a 3 min rest between working sets, regardless of program. Further, have you ever heard of/used rest pauses??? Rest pauses are some of the best hypertrophy/strength movements that Charles Poloquin prescibes! The whole point is to allow a mini recovery between reps, and an even longer rest period between sets to keep ATP at peak levels and prevent pumps (both of which mean more power per rep = better white twitch stimulation!).
Further, lifting schemes with short rest periods tend to make the muscle cell walls increasingly more impermeable. This is anti-productive for strength/mass training, since this means nutrients, oxygen, and wastes cannot be transfered. If you are in the 20-25 rep range, training for a triatholon, this is helpful.
Not to mention, the energy used in resistance exercises is intracellular (internal), since the cell walls are impermeable during contraction. As the ATP stores are quickly burned by white fast twitch fiber, the cell walls tend to stay impermeable until sufficient ATP has been synthesized, as a natural safety valve in case prolonged contraction occured. Eeventually this would cause anaerobic contractive failure (besides the free phosphate and lactic acid). To combat this, sufficient recovery is needed. If you “rush” the recovery, the cell perceives that as a prolonged contraction and the cell wall will again quickly become immpermeable leading to pre-mature failure.
If this program is designed to work red fast twitch fibers, than it would probably be set up in the 10-12 rep range, where lesser rest periods might be okay and one could get decent hupertrophy.
You also didn’t address that fact that as I read the ABBH II it prescribed to hit ALL chest movements in successive sets (6 total)! So, maybe 3 would be borderline, but 6 sets with only 60 seconds rest using your 7RM is not productive in my book!
