Wildfitness Retreats offers a way back-to-basics approach to total health with one- to three-week programs of "wild moving": boxing, trekking, or running barefoot on the beach. The Paleo-diet cuisine eschews "modern" additives, like wheat and dairy, in favor of lean meats and nuts.
In Malibu, a handful of nuts might be all you get for lunch at The Ranch at Live Oak, where the 7-day, "no options" detox and fitness program—they even ban cell phones—puts the Blueprint Cleanse to shame. Sunrise hikes kick off 10 sustained hours of daily activity, all fueled on a strict, 1,500-calorie, gluten-free, vegetarian diet. Consider the daily massage and bedtime in your rustic, luxe limestone-and-reclaimed-wood bungalow your dessert.
You'll find a less-intense regimen in the rainforests of Ilha Grande, Brazil, where The Island Experience offers twice-daily yoga sessions above an azul lagoon, sea-kayaking, and snorkeling, plus jungle hikes to remote beaches. Complimentary massage, capoeira lessons, and prime hammock and hot-tub time treat your inner beach bum, while carving your outer beach bod.
