WOW – April 11th


This week’s WOW is one that I have done many times on my own. I can surely attest to its grueling nature!

Have fun,

Max cycles in 15 minutes of:

Grok Crawl
Grok Crawl


Warmup: 30 second Grok Squat, three light sprints at 70%.

Today’s Workout of the Week is inspired by one of my readers, Will Shaw, who sent in one of his favorite workouts. It’s an engaging (but grueling) one.

You’ll need to plot out a large square or rectangle on the ground, either in your mind or with actual physical boundaries. Make it at least 20 meters by 15 meters. You could use a tennis court, half a basketball court, or, if you’re up for it, a full basketball court or half a soccer field. If you can’t find any of those things, plot out a big rectangle using four objects, one at each “corner” – cones, bits of clothing, rocks, sticks, whatever.

Starting from one corner, Grok crawl to the other side lengthwise. Then, spring up, change directions, and sprint diagonally across the rectangle to the other corner. Grok crawl up the side, lengthwise, again, then sprint diagonally to the other corner. You should have just arrived at your original starting position. Rest if you must. You’ve just completed a cycle. Complete as many cycles as you can in fifteen minutes.

As for the workout, that’s it. It’s simple and effective.

A few things to remember:

  • Really work on your transition between Grok crawl and sprinting. Explode up into the athletic stance, pivot, and blast into your sprint. Be quick and efficient about it.
  • If you rest a lot in between cycles, make up for it by increasing the intensity. Don’t rest and then take it easy during the exercise.
  • Grok crawl sprints are most effective when you keep those hips low. Don’t form an upside down V with the ground and try to be conscious of using your arms (pulling yourself as well as pushing), along with your legs. Don’t make it all legs, which is often the instinct.


Add weight by tossing on a weight vest. Add even more weight by having a partner along for the ride the entire time; have them latch on as you crawl and carry them as you sprint, then trade off each cycle (since it’s so exhausting). If you use a tennis court, consider incorporating some vaulting over the net for added flare.
