I first read the btgb about a year ago, have been watching this site off and on since, and about two months ago I built myself a highbar, some pbars, cleaned out the attic to use as a gym, etc.
About two weeks ago I decided to start at the beginning with the prerequisites. From about the second day on doing the prerequisites has caused me to have soreness (nothing major) in my calves. It even appears as if there is some growth going on in my calves too.
What about the PRQ's could possibly be working my calves?
