I use the nike speed rope you can find on salemat the tennis warehouse web site.,i have it in my gym bag... All wrapped up, and it works great. Its a fast rope, very well built. Not expensive.
The rope doesnt have "memory" at all.
When i started jumping I could barely do 30 seconds without it getting caught up in my feet. In total I would do just a few miutes.
Now i can jump for 45 minutes, doing several types of bounces.
If it gets caught up in your feet its most likely due to inexperience. But stick with .. Its a great workout
