Yes, I alternate walking, running, and bicycling on a regular basis, and have kept 35 lbs off for almost two years now, along with sensible eating habits.
I reccomend tennis as its very healthy as you use every part of your body and you will fell better aswell after a good game of tennis.Although biking is also good but tennis is better if you wanna work out and lose a few pounds. Because biking only works the legs.
