I have just purchased a set of rollers (with a resistance unit) and want to develop my aerobic base during the winter months. I have a high tolerance for the boring and tedious, and so I should be able to maintain my motivation to see this through. I have been searching for specific roller work outs that I could do to build my aerobic base over the winter, but have been unable to come up with anything specific on the Web. Does anyone here have any recommended workouts that I could do on rollers? If not, do you know if any websites and/or books or articles that would be helpful? Thanks, I appreciate it.
