But the big question that a lot of people have, is how do I become more fit?
You see- biking to work is not just another form of exercise. Every other form of exercise requires you to have the will power and commitment to continue doing it day after day, year after year. Whereas biking to work requires no self discipline. When your paycheck is on the line, you have no choice but to get on that bike and pedal to work!
Also- other forms of exercise typically require a dedicated time and place set aside for it. For example, you have make a special trip to get to the gym or swimming pool. Whereas for me, biking 6.5 - 7.5 mile to work takes me roughly the same time as driving (thanks to traffic jams here), so I am not spending any extra time exercising. The exercise is built into my commute to work.
