I AM POURING with sweat. Beside me is a Swedish woman in her late 20s who appears to be perfectly toned and a middle-aged Australian woman who is seemingly in very good shape too. Unlike me. Our personal trainer at this early-morning boot camp in Thailand is a young, lean, fit Thai man named Mongkol. He is merciless, and he has us running, jumping and hopping for almost an hour.
THAI-DYED: Chiva-Som is on the Gulf of Thailand, some 115 miles south of Bangkok.
