There is the TUT (Time Under Tension) theory in BB'ing that states that you want to move a greater amount of a work load (weight used in a exercise) in the shortest period of time. Getting a quicker pace to a BB'ing workout and keeping that Time Under Tension. . That means doing the given reps faster and the time between sets shorter. You don't want any period of increased recuperation between sets or exercises (TUT again). That would be self defeating for the purpose of putting max focus (and time) on the muscle(s) being worked. I call this the brief and to the point way of training. Quite a few BB'ers, past and present, follow this protocol for steady gains. I'm not a BB'er but have experience this style training for short periods (6-8 weeks) taking a break for heavier, max weight training methods.
90 seconds between sets is the usually pattern followed by the BB'ers I come in contact with. And 90 to 120 seconds between exercises working the same muscle area. Like benches to dips...90 to 120 seconds rest period.
Bigmacdaddy give a good example of how even making slight adjustments to a training program can give unexpected results , in a good way. Changing a rep scheme, the way a movement is done, rest periods (shorter...longer),weight used (light..moderate...heavy) can recharge training attitudes and training gains. I usually suggest 6 to 8 weeks on most programs. 12 weeks on some occasions. The body will adapt, fairly quickly, if keep on doing the same old exercise, the same old way. Change can do a body good.
When breaking into a completely new training program/style it will usually require 2 to 3 weeks to get adjusted to the bodies response....good or bad. If feeling that that program, after 3-4 weeks or so, is not fitting your needs, that drop it (no matter what others, or the "experts" say about it) and make a change to another style training program. BB'ing will depend on finding out what works for you and not what MR Big Balls of 2010 had done in workouts. That's usually BS, just trying to sell video's or training books. BB'ing is a great personal experimental effort. Selecting what gives you the gains that you seek.
Good Luck.
