If you thought it was genetics alone that gave Pippa Middleton that bum, think again. Ms Middleton hit the streets of the capital today proving she works hard for her famously toned tush. No trainer or over the top fancy workout wear was needed to spur Pippa along on her run, apparently being tailed by a pack of paps is enough motivation to keep the pace up!

With all the posh gyms and designer workouts available in London, Middleton's decision to stick with a good ol' fashion run certainly backs up her reputation of a fuss free 'normal girl'.

Is the sight of Pippa hitting the street enough to get you motivated to head out for a run? Leave a comment below and let us know.
