Running is the best way to get fit.
Forget it! There's no one best method to get fit. You have to enjoy your workouts or you will find reasons to quit. Nobody can get fit or lose weight or build muscle in an instant. Fitness requires time and patience, and you get rewards as you go along, not the least of it being improved self-esteem and confidence. If you are looking only at running or at instant success, you are looking for trouble!
