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: Vitamin K2 and Microworkouts

For today’s edition of Dear Mark, I’m answering questions about vitamin K2 and microworkouts. The last two posts on both topics garnered a number of good questions. What’s the best dose of vitamin K2? Should statin users taking vitamin K2, since statins inhibit vitamin K2 activity and production? Can vitamin K2 prevent or reverse arterial calcification? Is butter an adequate source of vitamin K2? What about vitamin D—does it synergize with vitamin K2? Regarding microworkouts, what if you can only do a couple pull-ups at once? Should you alternate muscle groups when doing microworkouts? Can microworkouts work with normal gym workouts? How does one do microworkouts in an office?

Are You Doing Microworkouts? Here’s Why You Should.

The fitness industry is in the midst of a renaissance. Flawed and dated strategies like sedentary recovery practices or overly stressful HIIT workouts are being replaced with cutting-edge practices that offer more efficiency and return on investment. Today I’m covering one emerging fitness strategy: performing brief feats of strength in the routine course of a day. Let’s call them microworkouts.

I’m talking here about dropping for a single set of deep squats in the office, hitting a set of max effort pull-ups whenever you pass under a bar in a closet doorway, or stocking your backyard with a hex deadlift bar or bench press and busting out a single set every time you pass by while taking out the garbage.

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?

Let’s find out:

Glute and Hamstring Workout

Jessica Gouthro from Paleohacks is joining us today to offer tips for strengthening glutes and hamstrings without traditional gym equipment. Enjoy, everyone.

Strong glutes and hamstrings are more than just nice-looking legs and a booty.

The glutes and hamstrings are the strongest muscles in our skeletal muscular system. When we strengthen these muscles, we can prevent strain and injury while also enjoying a greater ability to squat deeper, lunge pain-free, push heavy objects, run faster and jump higher.

To best train those glutes and hamstrings, you’ll want to emphasize both leg curling (knee bending) and hip extension (or straightening) actions for balanced training. One of the best exercises that do this is the glute ham raise, or GHR.

Very few exercises can isolate the hamstrings and glutes without top-loading excess weight on the spine or testing your grip strength with a loaded barbell. Although you may think this exercise looks easy in comparison to a Barbell Romanian Deadlift or Hip Thrust, it is just as challenging (if not even more so) when performed correctly.

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.
