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?

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.Read More

Today’s post is part two of a postpartum series inspired by a reader question. You can read part one here.
Diastasis recti (DR) is usually described shorthand as a separation of the ab muscles. More accurately, it’s a deformation of the linea alba, the line of connective tissue that runs down the front of your torso from your ribcage to your pelvis. The linea alba is basically where all the abdominal muscles meet in the middle; I think of it like the spine of a book. When the linea alba becomes deformed for reasons I’ll discuss in a moment, the rectus abdominis muscles, aka your “six-pack” muscles, pull apart. This is the (often visible) sign of DR.Read More
Yesterday, I explained the potential benefits and drawbacks of intermittent fasting for athletes. Maybe yesterday’s post intrigued you. Maybe you’re curious about this whole intermittent fasting thing but don’t want to sacrifice your performance in the gym or on the field.
What are my specific recommendations for athletes who wish to explore intermittent fasting? I’ve got twelve…plus some details about my own fasting and workout routine.Read More
To the average person, the idea of elite athletes skipping meals sounds like pure madness. Athletes are fine-tuned, well-oiled machines. Machines need fuel. You don’t see race car drivers running on empty to “promote training adaptations” in their vehicles. No, high performance requires high energy reserves.
Athletes need to eat, and eat well. Right?Read More
