My challenge for today!

So after my abs and arms, I needed to do cardio. What better way then sprints! I, did 6 110 yard sprints, and then pushrf my car to finish up cardio, so we did! :) This is not only cardio, but a full body workout. Throw your car in neutral and try it! For an extra challenge, you can push it up the drive way like I did, the incline makes it much harder! Enjoy! :)
