I read a couple articles recently, regarding rest periods between sets and the desired effect or goal of the different time periods. They basically laid it out like so:
1. 30-60 seconds rest beween sets, for muscular endurance.
2. 60-120 seconds rest, for hypertrophy.
3. 3-5 minutes rest, for pure strength/power.
In the spirit of this, I am currently using 3 minute rest periods between my squat sets, to promote pure strength in this particular lift for the time being, and 2 minute rest periods between all other exercise sets, because that time period would seem to be the bridge between hypertrophy and pure strength.
What does everybody say on this? Anything to it? Or am I just following another fad?
