DOES SIZE REALLY MATTER? DUH! ARE YOU JUMPING WITH THE RIGHT SIZE?
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 allows 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.
HOW TO CHECK YOUR JUMP ROPE SIZE
Step on the rope with one foot, bring your feet together, and pull the rope taught. Bring the handles together and point the top towards your chest. Only check where the cable ends - do not include the handles with rope size. If you follow our length guidelines, the cable will stop at your sternum or lower pecs. The rope should not go higher than this point. Any longer than this will have too much rope over head, and will slap the ground excessively.
THE RX METHOD PHILOSOPHY
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 that follows a progression for improvement just like any other high skilled movement.
Choosing the correct jump rope size is actually a 2 part process:
1. Choose a length that correlates to your height.
2. Adjust your positioning to fit that rope with adequate spacing overhead and underfoot. You have to do work too! There are many components to proper arm positioning.
