The latest fitness craze in Hollywood seems to be good old fashion bicycle riding. Celebrities like Brad Pitt, Angelina Jolie, Mena Suvari, Jennifer Ainston, Jessica Biel, and Karolina Kurkova have all been spotted biking around town. With all the workouts to pick from- why should cycling be your exercise of choice?

For starters, bike riding burns an average of 250 calories in 30 minutes (give or take - depending on your weight). In addition, biking:

1. Increases the blood flow to the brain
2. Reduces the stress levels in one’s body, by inducing a state of “healthy fatigue”
3. Strengthens a person’s muscles in the legs and back, reducing the risk of back problems
4. Reduces the risk of all kinds of heart problems and vascular diseases that may lead to strokes, high blood pressure and heart attacks
5. Is easier on the joints than running
6. Reduces air pollution
