At US trainer Joe DeFranco's New Jersey-based gym it's fair to say they have somewhat of a take-no-prisoners training philosophy. 'Every square inch of our facility is dedicated to getting athletes brutally strong, lightning fast and mentally tough,' says De Franco.

'There is no fluff at our gym! You will not find any TV’s, juice bars, fancy locker rooms, air conditioning or easy-listening music.'  What you will find is a bunch of massive blokes running around with entire weight stacks on their shoulders, sprinting on treadmills until they collapse and puking in bushes. Superb.
