Rx Jump Ropes are custom sized to each individual athlete’s height, for this reason please refer to the instructions below on How-To Size Your Rx Jump Rope.

Aircraft grade cable with PVC coating. Our lightest offering weighing only 1.3 ounces for a 9 foot length (excluding handles). Most comparable to traditional speed cables. The PVC coating does not retain memory and therefore uncoils nicely. This cable can produce the fastest cycle rate therefore the athlete must be extremely proficient at double unders.

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 plane. 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 plane. 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 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.

Figuring out the right jump rope size can be a tricky task.  If you are a beginner to intermediate skill level jumper (i.e. 0-50 double unders) it is important to begin with an approach that gives you a foundational starting point and then follows a progression for improvement just like any other high skilled movement.  Choosing the correct jump rope size is actually a 2 part process: First, choose a length that correlates to your height. Second, adjust your positioning to fit that rope allowing adequate spacing overhead and underfoot.

The Rx Sizing Method is a progression based approach with the goal to ultimately place you in a rope length that produces efficient mechanics and positioning. The suggested length correlates to your height to provide an abundance of rope clearance overhead and underfoot yet not so much as to force poor positioning and inefficient movement patterns. The Beginner to Intermediate length recommendation should be viewed as your starting point and all efforts should be directed towards moving to a shorter rope length over time.  A shorter rope length requires more compact positioning, which reduces fatigue in the larger muscle groups as well as produces a faster cycle rate per rotation.  In essence, a shorter rope will allow you to perform more work faster with less energy expended.

RX Sizing Recommendation:

Beginner to Intermediate (0-50 Double Unders)

If you are an experienced jumper measure your current rope or choose a length you know works for you.

The chart below will provide specific length recommendations for Beginner to Intermediate jumpers. Please use the images below to assess your current positioning and make the necessary adjustments to your recommended rope length from the chart.
