If its not the sunlight, fresh air, the sounds of the ocean that make these PT sessions a pleasure to be involved in, then it is the spirit of exploration and adventure that do the trick.
The weather ensures lesson plans are holistic allowing the body to rest well in areas not stimulated due to unique weather conditions and session plans.
Mentality is another ball game when dealing with outdoor fitness philosophy. When it's cold and dark we build up will power; When it's hot and pleasant we enjoy the earned gratitude!
Mentally and physically, outdoor PT workouts are simply the most fulfilling way to train your mind and body whilst getting results too.
