Want to get fit? Low on cash? No problem -- I know of a great way to get fit ... for less than $5!Want to know what this fitness secret is? It's no secret. According to Divine Caroline, the easiest, cheapest way to get fit is by ... jumping rope.

Haven't jumped rope since you were double dutchin' it on the playground? I hadn't either until I took up kickboxing and I quickly learned that jumping rope is hard work.

So dig out that old rope and get hopping. The best part? You can get an awesome workout in a hurry. Start out by jumping for no longer than five to 10 minutes. Once you're fit enough to do that, start jumping intervals over a 20-30 minutes time period. Want to know more? Read the full workout here.
