Coach,
I actually have a serious question to ask you that I know you are able to answer.
Are these numbers pretty good to follow for strength, 1 RM. How credible is the NSCA?

We use that as a guideline and yes, it's pretty accurate. As of the last couple of years the NSCA has been under scrutiny for not following up and checking the accuracy of some studies that they publish. Mike Boyle, called them out on a few of the studies because of the inaccuracy and really publishing just some stupid shit (just open a study journal and you can see what I mean). They got pissed at him and they had a falling out with Boyle and sent letters to each member saying that any member using Mike Boyle for CEU's will no longer be accepted even the past studies that were originally used.
Because of that, most of the people that follow Boyle (and there are some prominent coaches that have studied under him) are no longer renewing their certs with NSCA. The NSCA has lost a lot of memberships because of this.
