Pains of Bike Riding

At first I would have never thought that riding bikes would have been as difficult as it was. I grew up on BMX bikes but mountain biking is a totally different story. Going down hills wasn't the issue for me but going up hills was a lot tougher then I thought it would be. Riding bikes is definitely a different type of shape rather then the typical walking and jogging. The next day, I awake and went to my first class of the day and sat down. My bottom seemed to ache and I couldn't figure out what the deal was. It didn't take long for me to put it all together. The mountain biking had really taken a toll on me the day before. Now i'll be riding bikes a lot more to get into that type of shape, and it seemed to be a pretty fun day, especially with the 80 degree weather!
