Howdy.
I have been curious about this for a while. When I first touched a weight in high school, one of the rules of thumb that coaches and peers would preach is that you have to have 48 hrs of rest between training of the same muscle group / movement. Is there any truth to this with regards to optimizing hypertrophy and/or strength?
I know that BBM templates don’t adhere to this belief, and I’m guessing it’s more of a myth, but I wanted to ask.
Thank you!
