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...

Dear Mark: Hiking and Body Composition, Hiding Liver, Unconventional Testosterone Boosters, Cooked/Cooled/Reheated Potatoes, and Sirtuins

For today’s edition of Dear Mark, I’m answering five questions from readers. First up, why isn’t hiking giving one reader the shifts in body comp they expected? Two, is there actually a way to mask the flavor of liver? Then I discuss a few unconventional testosterone boosters, followed by a brief treatment of the cooked, then cooled, then reheated potato. And finally, are there any dietary activators of sirtuin proteins?

How to Exercise with An Autoimmune Condition

Autoimmune diseases really throw the body for a loop. You’re attacking your own tissues. Your inflammation is sky high. What’s usually good for you—like boosting the immune system—can make it worse. You’ll often restrict eating certain foods that, on paper, appear healthy and nutrient-dense. You take nothing for granted, measure and consider everything before eating or doing it. Sometimes it feels like almost everything has the potential to be a trigger.

Is it true for exercise, too? Must people with autoimmune diseases also change how they train?

Dear Mark: Isometrics and Yoga for Seniors, Plus How Aging Affects Recovery

For today’s edition of Dear Mark, I’m answering a few questions about exercising for seniors. Last week’s post drew a lot of comments, and a few questions about how seniors should train. First, I’ll explore isometrics as an alternative for building strength and power. Can you get away with only trying to move weight? Next, I show how yoga can be an effective strength-builder in older adults. Then, I discuss how aging affects recovery. Many people notice that their recovery time goes way up the older they get. I’ve noticed it myself. Why does it happen?

10 Uncommon Exercises For Maintaining Strength, Agility, and Power With Age

The older you get, the more important strength, agility, power, and lean mass become. This isn’t how most people approach old age. They expect strength and all the other trappings of physical capacity to degenerate, and so they do. It’s what happens all around us, every day. Seniors are feeble, right?

The weight room is scary for a lot of people. Hell, even able-bodied youngsters in the prime of their lives shy away from lifting heavy things. So, first things first: Seniors should definitely strength train. If you’re unsure of your form and capabilities, find a trainer who works with older folks and ensure your safety. Just get out there.

How to Move through Life with an Edge

Every former competitive athlete’s worst nightmare is that moment when you lose to a younger person doing the sport you love. When the cocoon of invincibility and superiority you’ve erected around yourself comes crashing down and a piece of your self-identity shatters. It can truly feel like the end.

I know the feeling. Several years ago on a family ski trip, my son challenged me to a downhill snowboard race. We’d been doing these races—and I’d been winning them—ever since he was old enough to board. It was tradition that we race, and that I win. It’s just how it played out.

This time was different. I was a newly minted member of the 6-decades club. He was a young man, fully grown, years of sports under his belt. He smoked me. It wasn’t even close. And suddenly I realized that despite being in the best shape of my life relative to my age, that upper limit was trending down.
