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 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
Thanks for giving Jessica Gouthro from Paleohacks such a warm reception last week. I’m glad you found her “13 Ways To Move More At Work” useful. She’s joining us again today to offer tips for those who are looking to ease joint pain. Enjoy!
It sounds counterintuitive, but it’s true: one of the best ways to ease joint pain is to exercise!
Whether you’re feeling aches and pains in your elbows or your lower back and hips, the key to managing and preventing joint and muscle pain is to exercise in the right way. If you have existing pain or joint discomfort, then you need to keep your workouts low-impact, but that doesn’t have to mean easy or ineffective.Read More
Good morning, folks. After a awesome week (and weekend) taking over the Whole30® Recipes Instagram (you can still check out all the great videos, tips and recipes I shared here), my team and I are taking a breather. Look for a success story later in the week. In the meantime, we have some practical ideas for your Monday morning. We’re shaking things up with a movement guide you can put into action at work today. Thanks to Jessica Gouthro of PaleoHacks for these awesome suggestions, and let us know which you’ll be adding to your routine.
Working at your desk all day doesn’t have to mean poor posture and an achy body. Whether you sit or stand at work, remaining sedentary for hours takes its toll on the body. After just a few hours, your body will begin to stiffen, your lower back will ache, and you’ll grow sluggish. (For a printable PDF version with photos, click here.)Read More
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.Read More
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.Read More
