Ready, set, sweat! Head to the beach for an early AM power walk, followed by rock-climbing and then a little yoga. After an afternoon of kayaking, get pampered with a deep tissue massage. Welcome to Bikini Boot Camp, at Amansala, an eco-chic resort near the cliff-hugging Mayan ruins at Tulum, Mexico, overlooking the sparkling Caribbean and white sand beaches of the Yucatan. Boot Camp ain't so bad when it's in such a purty place. After Hurricane Wilma's recent devastation, a few Yucatan hotels are back up and running, Amansala included. Set on the beach, 14 palapas are casually elegant: decorated with mosaic-tiled bathtubs, bohemian details and beds draped with mosquito nets. The dining cabana offers delicious communal-style meals, such as fresh caught grilled fish, mangos, jicima salads and other yummy low calorie selections. One-week camp is $1842, and includes six nights accommodations, all meals, two bike excursions, kayaking, yoga and exercise classes, two massages and one Mayan clay treatment, and all entertainment.
