EXTREME CORE WORKOUT - JAMES TRAINS KRIS GETHIN

http://www.grenade.com A 'bonus feature' on our series of DTP workouts with Kris Gethin of Bodybuilding.com - here we see Team Grenade's James St Leger turn the tables on the big guy, as James puts Kris through the James St Leger core strength workout. As a champion endurance athlete, these exercises are second nature to James - but for Kris as a bodybuilder, a lot of them are entirely new and therefore extremely challenging. After he's put our Grenade athletes through a brutal series of DTP workouts, see how Mr Gethin takes up the challenge.
