Obstacles This Helps With: Barbed wire crawl, low crawls, tunnel obstacles, any ground-based obstacle
The barbed wire crawl is one of those obstacles that looks straightforward until you’re face-down in the mud, dragging yourself forward inch by inch while your lower back cramps and the wire catches your shirt. It’s not glamorous. It doesn’t make for great Instagram photos. And it’s a lot harder than it looks.
The good news? It’s also one of the most improvable obstacles with targeted training. A little crawling practice and hip mobility work goes a long way.
What Makes the Barbed Wire Crawl Hard
The wire is typically strung about 12-18 inches off the ground. That means you’re either on your belly (army crawl) or on your back (rolling), covering anywhere from 30 to 100+ meters depending on the race. The terrain underneath is usually mud, gravel, or uneven ground.
Three things make it hard: the low height forces an unnatural movement pattern that most people never train; your hip flexors and shoulders take a beating from the crawling motion; and the distance is longer than you expect. What feels like it should take 30 seconds takes 3-5 minutes.
Two Techniques: Crawl vs. Roll
The Army Crawl (Face Down)
Lie face down, keep your hips low, and pull yourself forward with your elbows while pushing with your toes. Think “opposite arm, opposite leg” — left elbow and right knee drive forward, then switch. Keep your head down and your butt lower than you think it needs to be. The wire is unforgiving to anyone who pops their hips up.
Best for: shorter crawl sections, uneven terrain, situations where rolling would be too slow.
The Log Roll (Face Up)
Lie on your back and roll sideways like a log. Arms crossed over your chest or held tight to your body. This is often faster than crawling because your whole body moves at once rather than inching forward.
Best for: longer, flatter crawl sections where the terrain is relatively smooth. Not ideal on rocky ground (your back will feel every stone) or in thick mud (you’ll accumulate mud like a snowball).
The Hybrid: Start rolling. If the terrain gets rough or the wire dips lower, switch to crawling. Having both techniques in your toolkit lets you adapt on course.
The Training
Hip Flexor Mobility (3x per week)
The crawl position hammers your hip flexors and low back. If these are tight (and they are for most people who sit at desks), the crawl becomes painful fast.
Half-kneeling hip flexor stretch: 30 seconds per side, 3 sets. Squeeze your glute on the kneeling side to deepen the stretch. This is the single most important drill for crawl comfort.
90/90 hip switches: Sit on the floor with both legs at 90 degrees and rotate from side to side. 10 per side, 2 sets. This opens up the hips in the rotation pattern you’ll use during the crawl.
Crawling Practice (2x per week)
There’s no substitute for actually crawling. It uses muscles in patterns your body doesn’t encounter in normal training.
Bear crawls: On hands and feet (not knees), crawl forward 20 meters, backward 20 meters. Keep your knees close to the ground. 3 sets. This builds shoulder endurance, core stability, and hip mobility under movement.
Army crawls: Find a patch of grass and army crawl for 30-50 meters. Time yourself. Do this once a week and try to improve your time. The first session will feel absurdly hard. By week 4, you’ll be moving twice as fast.
Low bear crawls: Same as bear crawls but with your hips as low as possible. This simulates the height restriction of the wire. 3 sets of 20 meters.
Core Endurance
The crawl is basically a moving plank. Your core stabilizes your spine while your limbs do the work.
Plank holds: 3 sets of 45-60 seconds. Boring but effective.
Body saws: In a plank position on your forearms, rock your body forward and backward. 3 sets of 10 reps. This mimics the shifting weight pattern of crawling.
Dead bugs: Lie on your back, arms and legs in the air, and lower opposite arm and leg toward the ground without letting your lower back arch. 3 sets of 10 per side. This directly trains the core stability for the log roll technique.
Sample Add-On Workout (10 minutes)
Tack this onto the end of any training session:
- Half-kneeling hip flexor stretch: 30 sec per side
- Bear crawls: 3 x 20 meters
- Army crawls: 2 x 30 meters
- Plank hold: 1 x 60 seconds
- 90/90 hip switches: 10 per side
Race Day Tips
Go low from the start. The number one mistake is starting too high and getting snagged by the wire. Get low, stay low, and check your clearance before committing to a speed.
Pick your lane. If there are multiple lanes, look for the one with the fewest ruts and the smoothest ground. A smoother surface means faster rolling.
Protect your skin. If you’re wearing a tank top or short sleeves, expect some scratches. Some racers wear long sleeves specifically for the crawl. It’s a personal choice, but awareness helps.
Breathe. It sounds obvious, but the face-down position combined with exertion causes a lot of people to hold their breath. Breathe rhythmically and stay calm. The crawl is a grind, not a sprint.
