This is a timely article on loosing weight by biking on hills. Since I am planning on biking more often to work from West Falls Church metro I have been looking for a better solution to hills on the Custis trail close to the rosyln. If you know this tail then you know that it is a series of accents and decent that are more up and down when traveling away from Rosyln. This makes it a fun ride in the morning but a killer on the way back. So if I want to loose weight I should stick to the trail and follow the advice in the article of trying to stay seated on the bike for as long as possible.
