But doesn't that sound like junk volume? What is there to adapt to, if the effort induces minimal fatigue? Also, unless it was ineptly designed, it seems to me that the study might have been contrived to reach a desired conclusion. From what Baron reported in his first post, no reference appears to be made regarding the level of intensity as it relates to how close the sets came to failure in either group. The control group did 6 sets of 8 reps with 2 minutes rest between sets using the same weight. If they were able to do the same number of reps with the same weight on the last set as the first, then the first several sets were warm-ups and the weight was too light. The 3/7 method was obviously more intense because there was less rest, only 15 seconds, between "setlets." So while it was fairly easy to do the first few setlets of 3, 4, and 5 reps, the intensity ratcheted upwards with the last setlets because of the short 15-second rest between them. Meanwhile the control group was yawning with 2-minute rest between sets of underweighted exercise. I could be wrong, but I'd like someone to explain why.
