Perpetual youth is a whimsical notion suited to screen writers and 16th century Spanish explorers but a career requirement for Laird Hamilton.

In the ocean as many as five hours most days, the inventor of tow-in big-wave surfing, modern-day stand-up paddleboarding and hydrofoil surfing uses a unique diet and training regimen to maintain a chiseled fitness that astonishingly belies his 51 years.

Here, the father of three explains why he hasn’t had a drop of alcohol in a decade, heartily devours fat, hangs upside-down with regularity, pals around with an 83-year-old for inspiration — and keeps searching for the Next Big Thing.

1. Forget age. Just keep driving the car: I take better care of myself today not as an accommodation to age but to maintain continual high levels of performance and just to feel good. I have a friend, Don Wildman, who’s 83 years old — and the guy’s an absolute stud who works out with weights, mountain bikes, paddles, surfs every day. Don’s a living example of what it’s like when you just keep driving the car.

I think what happens is that we decide we’re old and we just stop, and everything stops working. There’s so much stigma and weirdness around being older. Don and I were watching a tennis match and the announcer was saying, “He’s 34 years old!” Get over it — and keep moving. Don’t wait until you have a health scare or collapse. Get off your [butt] and feel better now.

2. Take care of everyday priorities: The stuff you do every day — your sheets and towels, the food you put in your body — these are your priorities. Not a fancy car or fancy clothes or fancy watches. For instance, I used to drink red wine every day — nothing like a good Bordeaux — but haven’t had a sip of wine or beer in nine years and have no desire to. I realized that sugar is not good for your body and that alcohol is one of the biggest culprits.

The fact is that alcohol doesn’t taste good anyway. The reason people drink is to have some sort of sensation, right? So if you’re not into that sensation, it’s a waste of time. It’s a discipline thing too. My mom once said to me, ‘If you can’t be true to yourself, you can’t be true to anyone else.’ As proof to myself that I had the willpower, I don’t do it. Bottom line: If you want your rocket to fly, you put rocket fuel in it. I want to be able to do certain things at a certain level. I like the way I feel. On a daily basis, I feel better not drinking.

3. Be a fat-burning monster: I don’t eat energy bars when I’m out on the water all day. In fact, I don’t need to eat anything. My body runs off its body fat. That’s because I’m Paleo. I consume hardly any refined sugar (only if it’s in a salad dressing), a few raw dairy products and almost no wheat or grains. I eat plants and animals. I actually grew up that way in Hawaii. [Paleo researcher-kineseologist] Paul Chek taught me that your body has enough fat on it to run for days … and that sugar fouls up your machinery. So after I cut alcohol, I began eliminating sugar and sugary fruit. I refined it over the last two years listening to [Primal lifestyle guru] Mark Sisson and other Paleo people.

If you’re eating right, a triathlete can go for hours and hours on a couple tablespoons of almond butter and your own body fat. But if you eat refined carbs, your blood sugar spikes up and down and you’re sucking down gel packs to get it back up. I love espresso. … You could give me five shots of espresso, a quarter stick of butter, a quarter stick of coconut oil and other fat, and I’ll drink that. I could go for five or six hours and not even be hungry at the end. Because I’m burning fat.

4. But don’t be a zealot: I have a saying: ‘Everything in moderation, including moderation.’ I make it achievable, not stressful for me and people around me. I’ll use a little coconut sugar. … I’ve got friends who have to stick [to a particular diet] at all times, and the stress of that almost overrides the quality of the way you eat. My eating is not such a hassle that I can’t go anywhere.

5. Golf-ball your bare feet: I grew up barefoot in Hawaii and didn’t give a thought to walking on gravel, but I’d notice some people who’d been in shoes their whole life couldn’t even cross the driveway. The feet are loaded with nerve endings and are the key to balance — and I’m in the balance business. In fact, we all are.

I also believe the Earth is charged with an electrical frequency that matches your nervous system and immune system. So the bare feet allow us to absorb that energy and is a critical part of your wellness. Having them trapped in a boot, toes squeezed together, affects your whole system. To restore dexterity and balance after I’ve been in shoes too long, usually at my home in Malibu, I warm up a couple days a week by standing with one foot on a golf ball. I roll it around, poke it, put weight into tender spots. It’s amazing how your system will be stimulated through working your feet.

6. Watch your back: I’ve had back issues and injuries over the years. When your back goes out, you’re out of commission. I give it relief with stretching and inversion, and strengthen it with core work and stand-up paddle boarding. Someone once said, ‘If you did 20 minutes of headstands a day, you probably wouldn’t age.’ Gravity is always pulling us down, and inversion fights it. I do it on a teeter board or on an upside-down hammock, not gravity boots, which don’t allow your legs to relax and decompress.

Since your power comes out of your core, which supports the back, you have to fix tight psoases and weak abdominals. I do planks and rotational exercises with medicine balls and kettle bells on a Swiss ball. Any natural pick-lift-twist-drop movement pattern, like picking something off the ground and putting it on a shelf, builds core stability. The best one of all? Stand-up paddleboarding. It flexes the back and the stabilizers — and cured me.

7. Do the water workout from hell: To me, swimming laps in a pool is like punishment — being in a cage. Out of my disdain for lap swimming, I developed what in my opinion is the greatest exercise routine you can possibly do: a bouncing, no-impact, high-intensity strength and cardio workout that is a cross between swimming and weightlifting.

Holding small waterproof dumbbells in your hands, jump into a fairly deep 10- to 12-foot-deep pool and sink to the bottom. Then jump up as hard as you can to pierce the surface and gulp some air. As the weights pull you back, blow it out. Get in a rhythm; exhale as you fall, inhale [after] you blast up. The exercise blasts your legs, which consume five times the oxygen as your arms. It‘ll make you a better, stronger swimmer without having to swim laps.

8. Be innovative in all aspects of life: Coming up with new ideas keeps me young and excited. [Hamilton and Wildman invented the GolfBoard, a kind of skateboard for golfers that won the PGA’s New Product of the Year award in 2014. Wife, Gabby Reece and Human performance expert Brian Mackenzie launched their new fitness lifestyle brand XPT. He also has lines of stand-up paddleboards, superfoods, and clothing and fitness wear.] I think traveling to unique places gives you an opportunity to be active.

9. Get role models: It’s monkey see, monkey do. It’s hard to be the monkey that doesn’t see. We all need an example, a road map, to tell us what’s possible, a Jack LaLanne. Am I going to fret that I’m old and washed-up when I’m mountain biking and paddling alongside Wildman, who’s 83? He lives, wears and eats a youthful lifestyle. And, by the way, who does Wildman use as his role model, since all his friends are dead? Me! So get younger buddies too!

When your friends get older and say, “I want to go play some bridge, you say, ‘I don’t think so — I want to go jump off the bridge.’”

10. Make it fun: Having as much fun as humanly possible is one of the keys to staying young, so find fun, physical activities you love. I forget about the time when I’m out there on a [stand-up paddleboard]. Activities are better than the gym because you’re not looking at the clock.

You’ll do more reps in nature than you’ll ever do in the gym. You’ll go for hours and hours. And you’ll be thinking healthy thoughts — not about how old you are.
