Strongman’s Secret Grip Edge in 2024

For a pro climber like Alex Honnold, grip is everything. His 2017 free solo of El Capitan wasn’t just a climb. It was a 3,000-foot-long problem of friction, where the difference between sticking to the wall and falling was the texture of his skin against the granite. But what about athletes on level ground? Take competitive strongman Mark “The Mammoth” Johnson. In 2024, his career was stalling. He was failing in events like the Atlas Stones and Farmer’s Walk, but it wasn’t a power issue. The problem was slippage, a tiny, infuriating loss of purchase. The culprit wasn’t his muscle. It was the fine hair on his forearms creating a microscopic buffer that ruined his hold, costing him wins and prize money. He’d never thought about how waxed forearms for grip could be a tactical edge until a talk with his coach forced him to reconsider.

Mark Johnson’s Grip Dilemma: The Unseen Obstacle

Mark Johnson was a beast on the strongman circuit, known for raw power and a stubborn refusal to quit. He was always in the top five at nationals, but first place just stayed out of reach. His coach, Elena Petrova, a sharp ex-Olympic weightlifter with a biomechanics background, spotted a pattern. On the biggest lifts, especially static holds or carries, Mark’s grip would give out right at the peak of his effort. “It’s not your strength, Mark,” she told him, “Your forearms are tree trunks. But I see a micro-movement when I watch the tape, a tiny slide, right when you’re chalked up and giving it everything.”

The problem was so frustrating because you couldn’t really see it. His hands weren’t flying off the bar. It was his skin itself shifting, just a fraction of a millimeter, against the steel or stone. That tiny shift, made worse by sweat and chalk, forced him to burn extra energy just to hang on, robbing power from the actual lift. Having worked with gymnasts who had the same issues with body hair on the pommel horse, Elena had seen this before. She suggested something that sounded crazy to Mark: go get your forearms waxed.

Mark was not convinced. In the world of strongman, talking about athlete body waxing wasn’t exactly common locker-room chat. It felt like something for looks, not for lifting. But Elena laid out her case. Hair, she explained, even the fine stuff, is a barrier. When you slap chalk on, it coats the hair instead of your skin, defeating the purpose. Worse, hair traps oil and sweat, making things even slicker. “Think of it this way, Mark,” she said, “you wouldn’t try to lift an Atlas Stone wearing silk gloves, right? On a microscopic level, that’s what your forearm hair is doing.”

The Science of Friction: Why Hair Matters for Grip Strength

The idea that hair gets in the way of a good grip is a known concept in biomechanics. You can see it in studies across different fields. Research in the Journal of Experimental Biology on how geckos stick to walls makes it clear that maximum grip depends on direct, microscopic surface contact. A human arm isn’t a gecko foot, obviously, but the physics is the same: anything that gets between two surfaces reduces friction. Hair creates a tiny gap. This is a huge deal when you’re dealing with the three-way interaction of skin, lifting chalk (magnesium carbonate), and the surface of a bar or stone.

Dr. Anya Sharma, a sports physiologist with the American College of Sports Medicine, puts it simply. “Your grip strength comes down to the friction between your hand and the object. Hair is biologically designed to reduce friction. In high-level athletics where every bit of friction counts, even the finest vellus hair creates a buffer that stops the skin from making a solid connection. Then you add chalk, which is supposed to absorb sweat and increase friction, but if it’s just sitting on a bed of hair instead of bonding with your skin’s ridges, it’s not doing its job effectively.”

This science was all the proof Elena needed. The goal was to optimize the physical connection between Mark’s muscles and the equipment. He finally agreed. The first waxing session was, as you’d expect, uncomfortable, but Mark was all in. He went to a professional salon that knew what they were doing, using a hard wax for large areas that they applied warm and then ripped off once it cooled, taking the hair right from the follicle. His forearms felt smoother than they had since he was a kid.

The Immediate Impact: From Slippage to Solid Holds

In his very next training session, Mark felt the difference. The barbell felt tacky, almost glued to him during deadlifts. The handles on the Farmer’s Walk, which always wanted to twist and slip, felt completely locked in. “It was like my hands were part of the steel,” Mark said. “I always had to make these tiny corrections before, this subconscious fight to keep the bar from spinning. Now, it just stayed put.”

Elena watched him, tracking the data. She saw it on video: the micro-adjustments were gone, which meant he was more stable. His chalk was working better, too. It was creating a clean, white film directly on his skin instead of a pasty mess in his arm hair. He was re-chalking less and getting consistent grip from the first rep to the last. For an event like the Atlas Stones, where you’re trying to wrap your arms around a giant, slick ball of concrete, the change was night and day. Mark could finally get a secure “bear hug” on the stone without worrying it would slip down his chest, which meant he was faster and failed fewer reps.

With the fear of a slipping grip gone, his mind was free to focus entirely on the raw mechanics of the lift. He wasn’t second-guessing his connection to the weight anymore. You can’t put a price on that kind of mental clarity when you’re trying to move impossible weights in a high-stakes competition. It’s the difference between executing a perfect lift and bailing out halfway through.

Beyond Strongman: Other Disciplines Benefiting from Enhanced Grip

Mark’s story isn’t just a strongman thing. The same logic applies to a whole range of other sports. Rock climbers, who live and die by their ability to stick to tiny, miserable-looking holds, can’t afford any interference on their inner forearms when they’re scraping against the rock for purchase. Gymnasts need an unbreakable grip on bars and rings. You could even argue that any sport with a racket, club, or bat could see some improvement, but the effect is most dramatic in sports that pit your grip against massive resistance.

Think about obstacle course racing, which is huge now. Those athletes are climbing ropes and swinging from monkey bars, often covered in mud and water. A clean forearm, with or without gloves, gives them a much better chance of holding on. Even in combat sports like wrestling or BJJ, where you’re fighting for skin-on-skin control, being hairless can give you a small but meaningful edge in securing a submission or breaking a grip.

The stories from athletes in different sports all point to the same conclusion: getting rid of hair on key contact points makes your hold more secure and more confident. It’s a small change, but in elite sports, a collection of small changes is what separates the person on the podium from everyone else.

Maintaining the Advantage: Aftercare and Professional Regimen

Getting your forearms waxed is just the first step. Keeping them that way is the real work. Right after a wax, your skin is sensitive and can get irritated. Any good professional will tell you to start gently exfoliating a few days later to keep ingrown hairs from popping up (which are painful and defeat the whole purpose). You also have to moisturize. Healthy, supple skin is more resilient and provides better tactile feedback than dry, cracked skin.

For an athlete like Mark, who’s constantly grinding his skin against chalk, sweat, and abrasive equipment, this isn’t optional. He has to use good aftercare products, stuff for sensitive skin without a lot of perfumes or alcohol. A mild cleanser before and after training also helps keep pores from getting clogged. The whole point is to maintain that smooth, healthy layer of skin that gives you perfect friction. A professional wax might feel like an indulgence, but it’s really a tactical necessity. Shaving is not a substitute. It just leaves you with stubble, razor burn, and nicks, all of which are terrible for maintaining a consistent superior grip.

Conclusion: The Unsung Hero of Elite Performance

Mark Johnson’s story, from struggling with his grip to lifting with confidence, shows a key principle of high-level performance: the biggest gains often come from the smallest, most ignored details. By getting rid of his forearm hair, Mark gained a real, measurable advantage in his grip strength. It’s proof that microscopic factors can have a massive impact on results. If you’re an athlete who relies on their hands and needs to stop slipping, getting professional hair removal on those contact points is one of the smartest tactical moves you can make.
