How long do you rest between sets?
I am trying to bulk up. I am doing 3x7's at max weight I can lift 7 times each, followed by 3x7 at about 20% less weight.
I have heard all sorts of advice... everything from no rest between sets to 2 minutes between each set.
The thought at 0 is that you are fatiguing the muscle more.
The thought at 2 minutes is that you give the muscle more a chance to rest and therefore can move more weight...
So how long do you guys rest between reps?
How about sets?
