Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
One of the more underappreciated developmental milestones in an infant’s life is the act of crawling. First words, walking, reading – these get all the attention, but it’s crawling that helps kids develop the important upper and lower body strength that will serve as a foundation for later activity and basic movement. Some pull and push with their arms while scooting along with their knees. Others crawl with their elbows like soldiers slogging through a battlefield. Whatever their methods, when compared to kids who skipped crawling and went straight to walking, early crawlers seem to have better motor skills. They understand bilateral coordination (using the arms and legs in reciprocal movements), they have a better sense of depth perception, and all that time spent on their hands gives crawlers better grasping strength.
For today’s workout, let’s take a cue from babies. Your motor skills are already developed and I imagine your depth perception is fairly accurate. You can probably grasp pens all right, and when walking you’ve learned not to swing your left arm as you step with your left leg. A baby crawling is about getting a total body workout and developing every muscle group for later use in life. We don’t need to crawl to develop basic skills anymore, but we can still hone them. Incorporating crawls into your workout routine can train your body to work in concert with itself while increasing overall strength. Legs pushing, arms supporting, back pulling, abs twisting, core maintaining, body balancing: the crawl – done correctly and intensely – hits everything.
So what makes a Grok crawl different from your basic bear crawl?
The Grok crawl is ultimately about crawling, and it does use the classic bear crawl as a starting point, but the similarities stop there. To perform the Grok crawl, get in the bear crawl position – on all fours, back straight, butt slightly raised, core tight – and crawl quickly, using your arms and back to pull you as your legs drive you forward. After ten or so paces, leap as far as you can using your legs and arms to collect power, as if you’re pouncing on a small animal (if you see an actual small animal, feel free to pounce on it). Maintain the pace and repeat the leaping. Mix it up with a series of successive leaps, or a stretch where you simply sprint-crawl for 40 yards. Just let go. The great thing about crawling is that letting go allows instinct to pretty much take over, so you can focus on going hard and fast.
So that’s the basic Grok crawl, but there are tons of other quadrupedal motions you can use to switch it up. In fact, switching it up is absolutely essential to getting the most out of your Grok crawl workouts. Keep your body on its toes and constantly surprise it with new motions and new angles to optimize results and make exercise interesting and sustainable. A few suggestions include:
Treat the Grok crawl as you would any intense cardio exercise. Try Tabata intervals or my beach sprint routine (except with crawls), or anything at all, really. It’s a completely adaptable workout that’s good for beginners and experts alike.
