Last but not least, 22-year-old Royal Marine commando David McIntosh (above) poses in a pair of red boxing boots. He’s also known — and most famous — as ‘Tornado’ in Sky One’s TV entertainment show ‘Gladiators’. And exactly how did he get that killer body? “I’m in the Marines.

Kevin is only 21, but he's already experienced more than many people ever will. Stationed in Iraq for two years with the US military, Kevin earned the Bronze Star for bravery when his quick thinking saved an entire village from terrorist attack.
