Double Unders jump rope seminars for Crossfitters

Double Unders Seminar

It’s all in the timing.

A double under involves two rotations of the rope for a single jump. When double unders are performed consecutively, they challenge stamina, strength, coordination, rhythm, and timing, which makes them a coveted move for all athletes.

Since 2012, Tim Haft and Shana Brady have led double unders seminars at more than 70 CrossFit gyms in 14 states with great results.

The 2.5 hour seminar centers on Haft and Brady’s easy-to-follow 4-step methodology; simple, yet effective drills; and their keen ability to detect and correct virtually any rope jumping error.

Thanks to your coaching, I have gone from zero double unders to a current record of 20! Doubles were the number one thing I struggled with at CrossFit so I am really, really pleased.

I took your double unders seminar and did what you suggested. On my first day using your approach I broke my previous record by 15 jumps. And today, I PRd again with 50 consecutive doubles!

I can’t thank you enough for what I learned at the seminar! The key to success is persistence, but the real key is to learn from someone who knows how to do things the right way.

You and Shana were awesome instructors; knowledgeable, friendly, and so patient with everyone! I would recommend your clinic to anyone who wants to get better at performing double unders.
