*U.S. Orders Only

Rx Jump Ropes began as a simple mission to create a jump rope prescribed for CrossFitters. This meant a rope that was fast, functional and resilient. After dozens of prototypes and thousands of double unders, they figured out few important things.

First, one size does not fit all in the world of jump ropes.  Having a jump rope that is properly fitted to your body and jumping mechanics makes all the difference in the world. Every Rx Jump Rope is custom made when ordered by the athlete.

Second, going lighter is not ideal for most people. Everybody has a different level of coordination, dexterity, and articulation. Most people respond better to a slightly heavier jump rope.  Rx Jump Ropes carries different cable sizes to meet various work capacities and coordination levels.

Third, the key to consistency is eliminating as many variables as possible.  Most jump rope cords made out of rubber, pvc or braided rope have too much flex and stretch.  Rx Jump Ropes are made with coated aircraft cable that gives consistent feedback turn after turn.

RX Jump Ropes are fast, functional, and durable.  In a word, “smart”.  And best of all every single Rx Jump Rope is made in the U.S.A.

Sizing Your Rope

Method #1 - The most accurate method would be for you to measure a rope that you currently use. That's a rope that lets you jump with your normal posture using your normal mechanics while allowing for adequate clearance overhead (usually 6 to 8 inches) and a bottom out point within 12 inches from your toes..  That measurement is of the rope only, not including the handles. Please pay attention if your current rope has a flexible cord. The stretch in a flexible cord could add and additional 4 to 6 inches to an Rx cable. We will then custom cut your Rx Jump Rope to that exact measurement.

Method #2 - The next method is a 2 part process to find a general cable length.

1. First take your height if you're 5'6" or shorter and add 2'8" to it. Example: 5'6" plus 2'8" equals 8'2". Or take your height if you're 5'7" or taller and add 3' to it. Example: 5'7" plus 3'0" equals 8'7". Write down that length to reference later.
2. Next would be to follow the universal standard of measuring from the BASE of your sternum for athletes 5'7" or taller or to the MIDDLE of your sternum for athletes 5'6" or shorter, down under the arch of ONE foot and back up to the same spot on the sternum. Make sure to wear your normal work out shoes and stand up straight while taking this measurement.
3. Now compare the 2 lengths from Part 1 and Part 2 and either choose the longer one or split the length down the middle. Either one should be a reasonable length for you to jump effectively with. This is only a general guideline to help you get started.

Cable Choices

Five Cable Choices To Cover All Work Capacities:

Hyper 1.3 - Lightest speed cable around for athletes performing 100+ double unders. Requires tremendous wrist dexterity/coordination to maintain movement.  Offers the least amount of shoulder fatigue but also the hardest cable to feel if shoulders are already fatigue d.  Excellent cable when going for max reps of double unders.

Ultra 1.8 - Excellent all around speed cable for any athlete working 75-100 consecutive double unders. Requires more wrist dexterity/coordination than heavier cables yet give greater feedback than lighter speed cables.  Perfect rope for any max effort or high volume crossfit work out.

Elite 2.6 - Fantastic for athletes that are working 20-50 consecutive double unders. Great precursor to gain coordination before moving to lighter speed cables.  Also a great all around cable for any crossfit work out.

Buff 3.4 - Ideal for athletes who are connecting 10 or less double unders together. Nicely weighted to give great feedback yet offers very smooth turn over. Still a good, all around cable for any mid-volume crossfit wod or as a medium weight training rope.

Beast 4.1 - Heaviest cable available. Typically for larger, stronger athletes to give you the feedback you need. Most comparible to the original beaded jump ropes as far as weight.
