Sometimes I think that things are just better left alone. It's probably an age thing but I try to look at it mostly from a functional standpoint. The jump rope is a prime example of this. In the old days Mom would give us some of her leftover clothesline and we'd be out jumping. When you're a kid it didn't take any more than 8 feet of line to make that happen. Much different today!
People are having a hard time counting their jumps so a mechanical device now does that for you. The rope doesn't spin easily so we have to put ball bearings in the handles. Short jumpers and tall jumpers can't use the same rope so adjustable handles now shorten or lengthen the rope with ease in their little secret compartments. The ropes wear out faster the more you use 'em, DUH! You get the picture.
Even the lowly jump rope has to bend to progress.
Basically what used to be a free and easy way to get a little exercise has been monetized to the hilt. Imagine paying $170 for a jumprope "system", yeah, they're out there. Oh, it's beautiful, a marvel of technology, state of the art materials and a finish like a fine watch. This is utterly insane until you experience the smooth operation. You're going to want one!
Okay, back to the simple jump rope. Probably the best single aerobic exercise you can do for your heart, mind & body. Want an $80 jumprope, get it. $24, GET IT! $170, just buy the darn thing. I don't know if the results are measurable between the upgrades of one to another until the ropes start doing the jumping for you. The only thing I ask is that you have FUN doing it and DON'T DOUBLE JUMP.
Jumping rope puts a little pep in your step, she's fabulous!
