I spend summers in Canada to escape the heat. But problem is rest of the year gets very cold..and gloomy. U.S. is too big to generalize, you can have the highst end, most urban to most rural farm town. Problem with most of these suggestions is 1. Not as easy to obtain Visa 2. Currencies are high compared with Portugal. For personal trainng, how about Rio de Janeiro? You already speak the language and the people on the shores are obsessed with looking hot.
Asia in general is extremely difficult if you relied on English and next to impossible with Portueguese.
