I’ve always followed the guideline of resting 3-5 minutes between sets when doing heavy lifting.
Supposedly a minimum of three minutes rest is needed to rebuild ATP and allow the CNS to recuperate.
I’ve recently started to wonder if it would make any difference if I rested less than three minutes when lifting heavy.
As long as I rest enough to finish a set, does it matter how long I rest?
For example, if I do ten heavy singles with three minutes rest, would it make a difference in my training if I did ten heavy singles with two minutes rest?
