Nick Mitchell – weights and resistance

Behold – the trainer responsible for the heavenly bodies that stalk the Victoria’s Secret catwalk. Nick Mitchell, head of the Ultimate Performance personal training gym, doesn’t mince words when describing his sessions: 'I don’t care about being a client’s friend, and this isn’t a spa experience.' Nick offers the kind of extreme workout which can turn you from flab to fab in a jiffy – and he doesn’t mess around; his gym's dumbbells are the heaviest in London, his workouts the hardest. Brace yourself!

One-to-one training costs £130 a session.
