Trousers feeling a tad tight after Christmas? They must have shrunk in the wash. If you need a kick up the fitness arse, try boot camping abroad. Forget tiny food portions, these are about hardcore activities in epic destinations. Er, good luck.

Ibiza

If you think Ibiza is just a party place, you're wrong. Well, sort of. Yes there is all that, and it's great too. But it's also a rugged, picturesque island and the ideal location for a boot camp in the sunshine. Expect rock climbing, circuit drills, mountain biking and hiking. To avoid the temptation of Ibiza's bars, there are trips to the night markets - good if you're feeling fed up with the forced fitness. No1bootcamp.com

Kenya

Blue sky, white sand and running across dunes: that's exercise Kenya style. There are no fitness fads here; it's all about embracing nature and teaching your body to be healthy on its own. So, think 'wild eating' (easily digestible foods) and 'wild living' (respecting your body's natural rhythms). After all the swimming and crawling through tyres, there's that peachy beach to enjoy. healthandfitnesstravel.com

Swedish Lapland

Running is hard. Running in the cold is even harder. Running through snow and then spending the night on the freezing floor of the Icehotel? Yep, that'll finish us off. It is one way to see Swedish Lapland though, so if you like extreme fitness (and sub-zero temperatures) then don those long johns and start striding through snowy forests and over icy lakes. Don't worry, a Swedish sauna will help you feel semi-normal at the end of each day. discover-the-world.co.uk
