#1 Posted: 5/17/2011 5:13:29 PM Question for you guys out there....I am a novice in the world of exercise and nutrition but am looking to start getting into some cardio a few days a week. I was wondering if jump roping would be an effective way to do cardio compared to running, ellipticals, biking?? ALSO if you someone could rank the above mentioned forms of cardio for me in terms of burning calories I would really appreciate it  |
