This is the ultimate wellbeing treat: it might set you back more than a month's rent, but it would be worth the sacrifice for a once-in-a-lifetime trip to perfect your Pilates on an exclusive private island. Sign up for a week of intensive core-strengthening on beautiful Kamalame Cay in the Bahamas and take part in as many or as few matwork sessions as you like. You can also make use of the island's spa for facials, massages and all the luxe pampering treats a girl could wish for.

Pilates £650, rooms from £420, flights extra. Kamalame Cay
