Just saw this over farmstrength:
Dave Lemanczyk -
"Training with jump stretch bands and The Formulator is THE worst idea I have ever read in my life. Honestly, it IS the worst piece of "attempted training" I have ever witnessed. Risk WAY over benefit.
Training is simple and when kept that way it is most productive. There is no sense in reinventing the wheel."
Of course this blowhard offers NO reasons why. I guess we have to wait for the his "e-book". Mr Lemanczyk has since been removed from the friendly forum.
