How to Size your Rope
We follow two basic principles with regard to jump rope length; The first is “static” rope length. That’s the actual length of a rope not in motion. The second is “dynamic” rope length. That’s the rope in motion where the athlete’s mechanics can influence the effective length of the rope.
Our sizing chart will attempt to guide you to an ideal “static” rope length. This rope length is intended to fit a specific posture while jumping. That posture can be described as follows. Starting with your anchor point, which is your hand placement. Hands should be positioned at your midline axis and right at your frontal plain. Your hands can slide in or out along this axis depending on your shoulder’s external rotational flexibility.
Your elbows should be relaxed down by your side with your shoulders as disengaged as possible. Again external rotational flexibility may dictate whether your elbows need to pull backwards in order to keep your hands from shifting forward of your frontal plain. Once we have your anchor point isolated at your midline axis we then look for your jump rope to have an even turnover passing over head and in front of the toes with a minimum of 12” clearance at both points.
If we’ve met all of those standards then we’ve placed the athlete in the best possible position to have balance and symmetry between their body and their rope. It will now only depend on the athlete’s efficiency of mechanics to dictate their “dynamic” rope length
When viewing the sizing chart (see Images & Videos tab) please locate your height while wearing your normal work out shoes. Then see the indicated rope length recommended for that height. That is the measurement you would select when purchasing your Custom Rx Jump Rope.
Five Cable Choices To Cover All Work Capacities:
Hyper 1.3OZ - Lightest speed cable around for athletes working 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 fatigued. Excellent cable when going for max reps of double unders.
Ultra 1.8OZ - 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 2.6OZ - Fantastic for athletes who 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 3.4OZ - 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 4.1OZ - Great for bigger/taller athletes tackling double unders for the first time. Allows users to gain coordination while heavier cable provides the inertia to allow for slower rhythm. Also an excellent heavy training rope if you're looking for dynamic input.
