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...

15 Alternatives to Burpees for When You’re Tired of Doing Burpees

Whenever I’m strapped for time and equipment and still need a solid workout, I turn to the burpee. Burpees are bodyweight exercises, and thus require no equipment or weights. They are full body movements that employ every muscle group, require only as much space as you need to do a pushup, can be done anywhere, can be done slowly and methodically or quick for a sprint-like workout. If you’re ever outdoors and need to warm up fast, a set of 15-20 burpees performed as quickly as possible will get your body temperature up faster than anything. The pros go on and on.

25 Ways to Improve Your Insulin Sensitivity

Insulin does a lot of important things for us. It pulls glucose from the blood and fritters it away into our cells to be burned for energy or stored as glycogen. It prevents hyperglycemic toxicity to neurons, pancreatic cells, the arterial walls and the generation of excessive levels of reactive oxygen species. It even promotes muscle protein synthesis and helps augment muscular hypertrophy, especially following resistance training. Clearly, we need insulin. Without it, we’d die, as type 1 diabetics readily do without an exogenous source.

Dear Mark: A New Whole Grain Study, Advice for a Teen, Broken Leg Sprints, and The 3 Mules

For today’s edition of Dear Mark, we’ve got four questions and four answers. First up, there’s a new whole grain study, and some people are claiming it demonstrates that low-carb diets will lead to early mortality. Does it do anything of the sort, or is this yet another flawed observational paper? Next, a teen on top of his diet game who hopes he’s doing it right writes in with a list of questions. I answer them. Next, what can a person recovering from a broken leg do in the way of sprinting? Or should she just focus on recovery? Finally, a wild and free man is roaming California with three pack mules, flouting convention and leading a nomadic existence. Police are occasionally called and media attention is often attracted. What are my thoughts?

Dear Mark: More of Your 21-Day Challenge Questions Answered

Today, I’m doing another batch of 21-Day Challenge questions pulled from the ones you asked me two weeks ago. I managed to make it onto the third page of comments. I’d hoped to get through all of them, but with over 200 questions asked, the task proved insurmountable! Since they were by and large really great questions that deserve serious answers, though, I expect I’ll be drawing on them for future editions of Dear Mark. Stay tuned for that in the future.

This week, we’ve got questions about weight machine training, indoor sprinting, eating for drinking “more than moderately,” feeding kids, going Primal with a failing kidney, exercising kids, balancing sleep and exercise, going Primal as a vegetarian, and much more.

Better Than a Marathon: The 1 Mile Challenge

If you wanted schoolyard acclaim at my middle school, you didn’t bother with how much you could bench, how many pullups you could do, or how far you could throw a football. And you certainly didn’t bother with running a marathon. The true path to lasting seventh grade athletic immortality ran a mile in length. If you could break six minutes, you were fast. Break five and a half? You were elite. Once a week during PE, we’d line up on the track to test our mettle. Coach’d say go, click his stopwatch, and we were off chasing glory. You’d run and you’d run until you got to that final leg where you’d kick without even knowing it and propel your body past your rival to beat him and your own time. The mile was special.

Dear Mark: Young Guy, Low Testosterone; RS for Babies; and Sprints vs Tempo Runs

For today’s edition of Dear Mark, I answer three questions. First up is a young guy with low testosterone. He eats the right foods, does the right exercises, and has lived the right number of years, but he’s saddled with the testosterone of a much older man and wants to know why. Next, I discuss whether resistant starch is suitable or important for infants. The parents are benefiting from it, but does that mean an infant needs it, too? And finally, I explore the value of tempo runs – tough but doable runs maintained at the anaerobic threshold pace – for fat loss. How do they compare to my favorite fat burning exercise – sprints?
