Should all exercise be done in the gym? It’s all very well to be in a fitness gym but sometimes it’s good to get out and get some fresh air into the lungs. Of course, this isn’t always easy for those in the city, but if you have a day off you could easily go for a walk in a forest or up a hill. It’s also very relaxing which is somthign that’s so important in today’s stressful living filled with telephones and computers. Get away from it all for a few hourse at least.
