For a full bio, head over to Top Form Fitness. To understand Josh' strength-training philosophy, check out his articles on this site and books such as Get Lean. And of course his interviews & discussions in Gymchats #201, #202 and #209.
NB : if you'd like to work with Josh directly (and he seriously is a fantastic trainer), I highly recommend his online services. Fantastic.
Incidentally, if you’d like to discuss any of the stuff above, come and join us on the Straight to the Bar Community over on Google+. Absolutely free.
