The guys from Team Grenade meet the Royal Marines at the RM Commando Training Centre in Devon, England. The challenge was to tackle the actual Royal Marines Endurance Course, so the team needed to be in best ever shape. Here, we focus on three of the Grenade elite athletes, Jamie, Kirk and Shane, as they prepare in the gym for this toughest of challenges. Grenade were there shooting a high-impact trailer promoting the new 50 Cal pre-workout (click the link to see the full promo) - but the course itself was the real thing, no sortcuts.
Thanks to the Commando Training Centre Royal Marines for all their help on an amazing day.
