Rowing, double-unders, and shoe laces

Tonight's WOD was another one from CrossFit Endurance:  6x90:90.  Six rounds of 90 seconds all out rowing, followed by 90 seconds of rest.  Like many of the CFE workouts it sounds fairly easy, but it is much harder than it sounds.

After the rowing WOD, I decided to work on my double-unders with a quick 2-minute drill.   Double-unders a rope jumping exercise where you swing the rope under you twice for every single jump.  (Check out this video if you want to see what double-unders look like.)   The objective of the drill is to see how many double-unders you can do in 2 minutes.   It is something I need to work on for CrossFit anyway, so every few weeks I do the drill to see if I've improved.

For most of my workouts, I wear Vibram fivefinger shoes. These are shoes that are shaped like your feet (with individual pockets for your toes and everything), that have minimal padding in the soles.  The idea behind fivefinger shoes is to give you as close to a barefoot experience when running, walking, etc. as possible.


I am a huge fan of these shoes -- particularly for running -- and while I wear them for most of my CrossFit workouts, I don't like them for jumping rope. There are two reasons for this.  First, occasionally if you miss the jump, the rope gets caught between the toes of the shoes, and if you are racing against the clock, the last thing you want to do is waste time untangling a rope from your shoes.  Second, if you are swinging a rope at 300 miles per hour and it hits your feet, and you don't have shoes that have a reasonable amount of protection on top... well let's just say it brings out some of my more colorful language.   So for jumping rope, it's back to my Chucks




Anyway, about half way through the drill one of my shoe laces becomes untied.   Might not sound like a big deal, but if you clicked on that video link, imagine what might happen if a shoe lace is dangling in the path of that jump rope which, again,  is traveling at approximately 300 miles per hour... OK, the truth is that nothing really dramatic happens.  But it does tend to mess up the smooth rotation of the rope and it always makes me miss the next jump.  That typically causes frustration and, again, colorful language.

A quick bit of research and I came across what has got to be the definitive internet resource on keeping your shoe laces tied: Ian's Shoelace Site.  Who knew there were so many ways to tie your shoes!  I'm gonna have to check out a few of these knots to see if I can keep the laces from slowing me down next 2-minute drill.
