Why in the world would a 2 to 3 minute break, between sets, cause a muscle group to be more proned to injury? That really sounds unfounded and goes against established training logic. The body will "cool down" (meaning, returning to a normal static function) slowly, given the amount and length of stress involved. It can be a matter of the heart rate, breathing, body temp, etc as it is the CNS it's self (the chief factor) returning to a normal state.. And this may be gaged on hours, rather than a few minutes time. Most strength athletes can take hours to finish a workout. Having spaces of 15 to 20 minures, or more, between training lifts. And more even between the ne
xt exercise.
Listening to one's body is not always the best idea for setting a workout pace. The body tends to lasp into periods of taking longer time between efforts, wheither we are aware of it or not. For BB'ing, a steady pace is required. That original idea of a 45 minute workout can turn into an hour and a half of gym time, if time is allowed to get away from us. That's when a stop watch comes in handy when training. Good Luck.
