But for those of us without the benefit of a world-class soccer star next door, there comes hope in the shape of boot camp, with the first one for men opening its doors this month.
The New You Boot Camp - which has already attracted the likes of Jade Goody and Michelle Heaton when they've been in need of a short, sharp shock that sees pounds and inches disappear in days - is holding the UK's first Male Boot Camp from January 16-23 in the Brecon Beacons.
A week-long residential course, it combines strict diet and intense exercise with the intention of burning fat and increasing strength, stamina and energy under the tutelage of military personal training instructors. It's tough, but it works.
Prices start from £1100; visit www.newyoubootcamp.com for further details.
