Many people think working with a personal trainer involves a gym. Wrong. The best part about training a person is working in places that are near where you live. In Toronto my beautiful garden is perfect or in beautiful High Park or in a persons own home or backyd.
In Ajijic Mexico on Lake Chapala working out on the Malecon is as good as it gets. I use some old fitness structures that are busted and the childrens playground.
In Florida I love going to Cemetary Pt Boardwalk or the playground park in Cedar Key where I use some of the play structures for various exercises with bands or a towel. Being in nature in peaceful surroundings with some good music and a bit of motivation is all you need.
