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...

How Does Alcohol Affect a Workout?

Winter is here. It’s cold outside—often cold and snowy and/or rainy enough to dissuade most people from extensive outdoor activities—and extremely warm indoors. Families are getting together, companies are throwing holiday parties, we’re eating, drinking and merry-making. Alcohol is everywhere, and many of us will be drinking more than we usually do. In fact, this time of year presides over a sharp spike in alcohol consumption.

What’s it mean for your workout?

After looking at the research, at first glance, I’m going to be honest with you: It doesn’t sound good.

Why Grip Strength Matters—and 10 Ways to Build It

The scientific literature is awash in correlations between a person’s health status and various biomarkers, personal characteristics, and measurements. As we hoard more and more data and develop increasingly sophisticated autonomous tools to analyze it, we’ll stumble across new connections between seemingly disparate variables. Some will be spurious, where the correlations are real but the variables don’t affect each other. Others will be useful, where the correlations indicate real causality, or at least a real relationship.

One of my favorite health markers—one that is both modifiable and a good barometer for the conditions it appears to predict—is grip strength.

Why an “Ab Routine” Isn’t Necessary (and What I Do Instead)

One of the first things people do when they start working out is focus on their abs—crunches, sit-ups, leg lifts, bicycles, and the like. I mean, who doesn’t want a six-pack? Entire fitness schools have sprung up around the idea of targeting your abs with direct work. Take Pilates. In its purest iterations, it’s considered a “total body” philosophy, but the way most classes seem to go you end up spending all your time doing a bunch of complicated crunches and other targeted ab work (and grimacing every time you cough for the next week).

Let me make a radical proposal here. All this ab work isn’t necessary.

Fasted Workouts: When They’re More Effective (and How I Incorporate Them)

Fasted workouts are a controversial topic in the fitness world. To some, the idea of working out without “carbing up” or doing the pre-workout protein shake is unthinkable. Won’t my performance suffer? Won’t my muscles shrink? Won’t my body think I’m in the middle of some horrible famine and go into starvation mode?

To others, fasted workouts are sacred tools, the perfect antidote to modern decrepitude. When I train in a fasted state, I can will my adipocytes to release fatty acids and feel the heat as they burn, hear the barely audible *pop* of muscle satellite cells replicating and proliferating, and see visions of my future physique through my gaping third eye. 

Where does the truth lie? Let’s look….

Urinary Urgency and Incontinence: Why It’s Not Just Age

Most people chalk urinary incontinence and excessive urgency up to age. We get old, stuff stops working, we wake up to wet sheets. Cue jokes about adult diapers and investing in “Depends” futures. It’s not entirely out of line. Aging matters. There’s just more to it. Like other aspects of “aging,” incontinence and unreasonable urgency don’t just “happen.” Aging may hasten or accompany the decline, but it’s by no means inevitable, unavoidable, or unmitigated.

There are surgical treatments available, many of which involve the implantation of balloons and slings and rings and hammocks. Those are beyond the scope of this post, which will focus on exercises and other less invasive interventions and preventive measures.

Mid-60s Check-in: 5 Ways My Workout Has Changed

I’m 65, and though I’ve been able to stave off the worst of what normally passes for the “aging process”—as can almost anyone by paying attention to how you eat, sleep, train, move, and live—the fact remains that I’m not training like I used to.

It’s not so much that I’m “losing” a step, although it happens to the best of us. It’s that I’ve totally transcended the need or desire to train hard for the sake of training hard. There are no more competitions. My ego is content on the training front. I’m not wrapped up in pounds lifted or miles run.
