Many studies have shown that the people who lose weight and are successful at keeping it off have found a way to make exercise a regular part of their life. I think a lot of people focus more on cardio in order to burn calories, but strength training is just as important to weight loss. It helps insure that the weight you lose from all that cardio is more fat than muscle, and it boosts your metabolism, so that the cardio becomes more effective and you burn more calories even at rest.

And keep riding that bike!!!!
