I usually have coffee at Starbucks with my girlfriend or watch a movie during rest days. It relaxes me whenever I am with her. Sometimes we also cook at home and just spend the rest of the day watching movies in our dvd player. Relaxing is easy as long as you forget about things that make u worry and just spend time with people you love the most. It doesn't have to be expensive as well, you can just relax anywhere like at home or go somewhere else that it quiet and comfortable.
