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...

Archetypal Resting Positions: How Sitting Like Your Ancestors Could Save Your Health

Tennis elbow, Achilles tendinitis, osteoarthritis, and other connective tissue injuries are on the rise. Athletes have always gotten them, but it’s only in the past few decades that regular folks are getting them too. For some connective tissue injuries, non-athletes outnumber athletes. That shouldn’t happen if the conventional wisdom—injuries to tendons, ligaments, and cartilage occur only because of overuse or overloading during intense physical activity—were true.

Now, of course the way we train affects the health and function of our connective tissue. Acute injuries absolutely occur. Overuse injuries absolutely develop. But that’s to be expected. Athletes put their bodies through a lot, and there is going to be fallout from that. Where those injuries shouldn’t be happening is in regular, everyday folks who don’t train for a living or engage in intense physical competition on a regular basis. And yet that’s exactly how it’s going down in the world today. In one recent study, the majority of patients with Achilles tendon injuries couldn’t attribute their condition to working out or playing sports. In other words, they just got it.

CBD For Performance: What We Know So Far

I left the pro athlete world a long time ago. I no longer compete. I don’t train with the intensity and volume it’d take to win races. But I do pay attention to what’s going on in that world, and I still have a lot of friends who never left it. Developments there often foreshadow developments in the rest of the health world. And after things like keto, MCT oil/ketones, and collagen, the performance hack that’s blowing up among elite athletes is CBD oil. Almost everyone I talk to who puts in serious training and competing time (in a variety of sports and pursuits) is dabbling with CBD.

What are they using it for?

Dear Mark: Antibiotic Recovery, Sprinting on Keto, Preparing for Bad Sleep

For today’s edition of Dear Mark, I’m answering three questions. First up, what can a person do to help their gut recover its barrier function after too many antibiotics? Are there any foods, supplements, or dietary strategies? Second, what can explain rapid fatigue during sprint sessions on a keto diet? Is this simply part of the deal, or are there modifications you can make? And finally, what do I do when I know I’m going to get a bad night’s sleep?

Dear Mark: Exercise-Induced Asthma, CBD for Diabetes, Warm-ups In the Morning

For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with exercise-induced asthma? Is there anything we can do to lessen its impact and incidence? Second, is CBD oil helpful for diabetics? And finally, do bodyweight exercises always require warm-ups? What about workouts in general—do you need to warm-up before every single session?

Dear Mark: Protein Efficiency in Seniors, Earned Carbs, Hardgainer with Limited Time

For this week’s edition of Dear Mark, I’m answering three questions from readers. First, is the reduced protein efficiency in older adults due to inactivity, or is it something inherent to the aging process, or both? Second, how does a person know if they’ve actually “earned” any carbs? Does everyone on a keto diet earn carbs by virtue of exercising, or is there more to it? And finally, how can a hardgainer with a packed schedule all week long and limited gym time maintain what little muscle mass he’s managed to gain?

My Favorite Way To Play: Ultimate Frisbee Workout (with Video)

I’m a believer in working hard AND playing hard. When we get stuck in patterns of overwork and overstress, we lose the important connection with our creative, intuitive, playful selves. Our work suffers and so does our happiness (which means everything else, like our relationships, will, too). Stuart Brown, one of the world’s leading experts on play, calls play a “profound biologic process.” What we all know (or used to know until modern living helped us forget) is that play is an essential component of our physical development and general well-being. From a personal standpoint, the older I get the more I recognize play as the linchpin for my own sense of vitality. As a result, I prioritize play—even above exercise. Fortunately, however, I’ve grown into a new relationship with fitness as a result of play. I gave up the slog of grueling training regimens decades ago now, but to this day I’m still living more deeply into a play-based fitness vision. Let me show you a bit of what that looks like for me….
