  1. Extremely Pleased w/this Jump Rope!!

    Posted by Ibe on 21st Apr 2014

    I'm a big guy (6'3", 245lbs), and I got both the Buff and the Elite....and the Buff is much better because it provide more feedback and control.....i.e. I know where the jump rope is at all time.....and I can actually get more double unders out of it....I might even recommend the Beast. You will not be disappointed with the RX Jump Ropes....this is coming from someone that is always skeptical.....but because I like this rope so much, I'm taking the time to review it!! Good luck with your training!!

  2. Solid product and helped me finally get II Unders!!!

    Posted by Ben on 17th Apr 2014

    Tried two other ropes beside the RX and just couldn't get it done. RX was recommended to me because of the various ropes available that could help me. I tried for 2 years with other ropes. Within 1 month I was getting 5-10 II unders in a row and have greatly improved since. It helped me, maybe it can help you!!

  3. Double Under Master

    Posted by Steve on 26th Mar 2014

    These are my 2nd pair since i've upgraded to a lighter cable. Great that I only have to purchase the cable and not the handles. Took about a day to get used to the lighter weight from the previous which I believe were 4.1.. Because my form is not so great, I added an additional 6 inches to the rope giving me 3 inches on each side. I'm now about to link DU with ease. Great product, highly recommend. Plus all my other crossfit buddies like them and are able to do DU's with them compared to not doing any with the other ropes provided by the gym.

  4. Definitely helped

    Posted by Eric on 2nd Mar 2014

    I've been trying for years to get double unders for several years and have had limited success. Dropped down to this cable size and added 2 inches to the length and I am slowly getting better. I just completed 14.1 with 63 reps, 48 of which were double unders. I think with that I did more doubles in that 10 minutes than I have in the 3 years I've been doing CrossFit and a hunter's version of CrossFit, TrainToHunt.
