Meet Mark

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...

Vibrant Health is About More Than Food

I’ve been thinking about human health for a long, long time – pretty much my entire life. When I was running marathons and battling injuries and illness, I was missing it, and so I sought it. I figured moving on to triathlons would help, maybe by “spreading the damage” across three disciplines, rather than just the one, but that didn’t do it. And so I started tweaking my eating plan by paying attention to anthropological evidence of the human ancestral diet. Obviously, this worked, and for a while, I felt I’d found the optimal path to human health. Things were good.

But my journey didn’t stop at diet. It wasn’t enough. My physical activity had to change, too: resistance training; sprints; hikes, walks, and other long, easy movements; and a marked de-emphasis on Chronic Cardio.

Announcement: New Grok On! Shirts Available

They’re long overdue, and finally here. The myriad of email requests worked. I present to you, women Grok On! shirts:

The white on purple V-Neck is a 100% fine jersey cotton. The black on light-turquoise Tank Top is a form-fitting tri-blend racerback (50% polyester, 25% cotton, 25% rayon). One of my crew members wore the tank to the gym yesterday and gave it her workout-worthy stamp of approval. Both are high-quality, American Apparel-brand shirts, and available at for $19.95 a piece.

Contest: Where in the World is Grok?

The Prize:

Toys! I write and talk a lot about nutrition and exercise, but there’s so much more that goes into health and wellness (stay tuned later today for an article on this topic). One of these is “Play.” So I’m giving away some stuff to play with…

Djubis. Frisbee is fun, but occasionally you need a change-up. Enter the Djubi. My best description of this game would be slingshot lacrosse using the rules of Ultimate. The balls have good zip, heavier than modern-day Nerf fare, they’re more akin to the old school, tough 1980’s Nerf balls that could obliterate a Lego castle if shot from an air canon. A box of these arrived at my office a couple weeks ago and my crew and I wasted no time cracking one open and having some fun. Tip: They’re best used in a large, open space, because they can really fly.

You may want to do this as a group, so the winner of today’s contest gets five pairs of Djubis. That’s enough for a ten person game. BONUS: Djubi is giving a 30% discount for readers who use “PRIMAL” when placing an order on (discount doesn’t include shipping).

Halfway Through the Primal Blueprint Challenge

The Prize:

A Portable Pullup Bar courtesy of Trapeze Rigging. I’ve been using this thing for over a year now. It’s the bar I use in my Essential Movement videos. I used them up at PrimalCon. I’ve got one at the office that has been a stalwart tool for the Worker Bees. It’s a simple design, breaks down easily into a carrying case, works great in a garage, backyard or if you want to take it to the park to add some pullups into a sprint routine. The height of the crossbar is adjustable to allow for dip exercises as well. Enter today’s contest for a chance to win the Primal workout gear.

The Prize:

More fresh Alaskan salmon! Courtesy of Wild Pacific Salmon, the winner of today’s contest will receive 3 lbs of wild caught Copper River Chinook salmon fillets overnighted to your door.

The Contest:

One of last year’s contests was so neat, I decided to bring it back. Originally inspired by a NY Times photo montage featuring families from around the world surrounded by a week’s worth of their groceries, I told readers to surround themselves with a week’s worth of their Primal groceries. Check out the results from last year.
