Video: George North talks about Wales' gruelling training regime in the gym
Interesting stuff from the Lions winger.
Wales are going to need every single competitive advantage that they can gain in the World Cup as Gatland's men are in arguably the toughest pool, England and Australia are waiting for them.
Ireland will testify to the fact that Wales are capable of beating anyone on their day though and you can't rule out any side that can boast about having the George North in their ranks, injuries permitting of course.
Wales' preparation for any big tournament usually takes them to the Sparta training camp in Poland and North has provided an interesting insight into the work that goes on in the gym.
Take a look.
