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...Tell Me More
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:Read More
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….Read More
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.Read More
We get lots of questions about how a ketogenic diet works in the context of exercise: Is it possible to maintain one’s fitness (strength, endurance, performance) and also drop one’s carb intake to ketogenic levels? Is it advisable? Will it help me lose weight faster?
Mark already addressed some of these topics, but it’s clear that many people still feel uncertain about how to pair a keto diet with their current workout routine.
Rather than write a single behemoth post, I’m going to tackle this in two parts. For today, let me talk keto and cardio, specifically how keto works for the average fitness enthusiast who thinks more in terms of general exercise. In a couple weeks I’ll follow up with a post on keto for runners and other endurance types who tend to focus on training programs and racing.Read More
For today’s edition of Dear Mark, I’m answering a couple of questions from the comment sections of the last couple weeks. First, it’s been established that fasting and exercise both raise growth hormone. What about fasted exercise—does that have an even stronger effect? And what about continuing to fast after your fasted workout? Then, I discuss the inevitability (or not) of wear and tear on the arteries from blood flow-induced shear stress. Is shear stress “bad,” or do certain factors make it worse?
Let’s dig in.Read More
Jessica Gouthro from Paleohacks is joining us today to offer tips for bodyweight-focused arm workouts. Enjoy, everyone.
Do you ever have those days when you want a good arm workout, but you don’t have any workout equipment?
Curls, presses, tricep kickbacks, and rows are all great for your arms if you’re at the gym with plenty of dumbbells, barbells and cable machines. But what about those days that you just can’t make it to the gym—or simply don’t want to?
Luckily, I’m here to prove to you that a good bodyweight workout is just as good as what you can get at the gym. The best part is, you don’t need anything other than yourself and just 15 minutes at a time to sculpt and tone your arms into incredible shape.Read More
