As we know, I am a frequent business traveler. I have my yoga and cycle studio that's around the corner, and I get a yoga mat delivered to my room. But what about when I am traveling for leisure? We recently got back from a cruise, and despite being surrounded by water, found ways to keep fit. In addition to utilizing the ship's gym every day we also picked excursions that were more on the active side than the leisure.
In San Juan we went on a 12-mile bike ride around the city. We went up a few hills, saw some of the local areas that we otherwise wouldn't have, and highlights of the city. Our guide told us great local-folklore and made it so that we really could indulge in some of that tasty food I had heard about.
In St. Maarten we went snorkeling by the famous beach where the airplanes land right over your head. We got to experience one of the "must do" activities while also getting to swim around and explore the crystal blue waters.
In St. Kitts we had planned to go hiking up a volcano, but after reading reviews, opted for zip lining instead. It was such a cool experience. While more on the easier side we did still use some of our upper body strength. 
I like to find these kinds of funtivities on our vacations because I just feel like we get to experience more than if we were just shopping.
