Bicycling
I have a friend who had found bicycling, not just a sport, but a way of life. Bicycling is also not just an exercise. Imagine how much money you can save when you go to places using your bike? It cultivates your body. It provides the ultimate fitness as you can be faced with different challenges. The sport is fun and competitive.
You can try different routes and terrains, and as you overcome every hindrance, you can feel the best feeling in the world that you can still do more and face all. The speed that you take and the resistance of the path that you choose will determine how much calories you can burn in one cycle. This exercise is best if you want toned muscles on the legs and for the lower body work-out.
