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...

Are CrossFit and Primal Compatible?

By Mark Sisson

Different crossfit equipment used for crossfit training at fitness clubBack when they were infants, CrossFit and paleo were the best of friends. Robb Wolf was giving CrossFit nutrition seminars. CF boxes were running paleo challenges and offering meal plans to clients. Tens of thousands of people were introduced to paleo through CrossFit and CrossFit through paleo.

Over time, however, they drifted apart. CrossFit met and fell in with the Zone Diet—a calm, well-mannered lad with impeccable balance, and paleo’s dad got a job in another city. They ended up going to different schools. These things happen. It’s fine. Both CrossFit and paleo are better versions of themselves for having met each other.

I’ve been interested in CrossFit for the better part of a decade. I’ve been to several of the Games. One of CrossFit’s best (and best-known) coaches, Kelly Starrett, was a presentee at PrimalCon Oxnard and a contributor to MDA. The infamous Grundler Brothers were early supporters of the Primal Health Coach certification program. Without CrossFit’s early endorsement, I’m not sure ancestral health would be as big and influential as it is today.

For the past year, my Primal Health Coach team and I have been working with Absolution CrossFit (of LaGrange, IL) co-owner and coach Laura Rupsis to understand what CrossFit athletes are missing in their diets and lifestyles. We’re convinced we can help them. I’m convinced we can help coaches help their clients using a Primal approach.

CrossFitters want:

To perform better. They’re interested in eating healthy food, but they don’t want their performance to suffer because of it.

To lose body fat and gain muscle. Who doesn’t? Losing body fat can improve performance in exercises where you manipulate your own body weight, but not if it means losing muscle and strength.

CrossFitters worry about:

Getting enough calories. With Paleo diets it’s notoriously hard to overeat, which is great if you’re trying to lose weight, but not so great if you’re trying to support an active training and competing schedule.

Getting enough carbs. I don’t blame your average CrossFitter for giving up on paleo. Keeping up with WODs while eating lean meat and getting your carbs from broccoli and asparagus sounds like hell. It doesn’t have to be that way on Primal, and I’ll show you how.

Burning out. CrossFit is taxing. There’s no way around that. And our real lives are busier than ever. Between kids, work, commuting, cooking, cleaning, and, hell, living, we all have a ton on our plates. Throwing one of the most intense training programs in the mix can push people to the breaking point. I’ll explain how going Primal can help prevent or mitigate burnout.

Many of the top CrossFitters have given up on paleo, opting for more flexible diets. Orthodox paleo just doesn’t work for the highest level of CrossFitters, who expend a ton of energy and eat a ton to compensate. And we can guess that this isn’t a spurious breakup. CrossFitters are students of the body and the inputs that make it run smoothly. If they’re moving on from paleo, something isn’t working.

But there’s a problem: Many of the most influential CrossFit bloggers, thinkers, and coaches are throwing the baby out with the bathwater. They assume if paleo doesn’t work, Primal doesn’t either. Researchers even released a study showing that paleo eating undermines the benefits of CrossFit training. It was just retracted for being, well, completely wrong, but it goes to show the forces arrayed against the union of CrossFit and paleo.

Although paleo and CrossFit have drifted apart, parallels remain. CrossFitters don’t fear fat, eat plenty of animals, understand the importance of plants, and love them some bacon. Even the movements prescribed by CrossFit are ancestral at their core—squatting, picking things off the ground, running, jumping, bending, reaching, climbing, hoisting, pressing things overhead, pulling—only performed at greater intensities.

Rather than merely recreate the paleolithic movement milieu, CrossFit transcends it in many ways.

CrossFit asks you to go as hard as humanly possible without breaking down, sacrificing your quality of movement, and hurting yourself, all while paying homage to your heritage as a human animal. That’s no joke, man. And they take it seriously. All the CrossFitters I know spend almost as much time warming up and doing “prehab” mobility work than they do working out. Sure, people get injured—as they do in every sport. Contrary to popular belief, CrossFit has never been shown to be more dangerous than other types of training. Recent studies show that CrossFitters experience no more shoulder injuries than other athletes, for example. If anything, CrossFitters get fewer injuries than athletes on other programs.

My point is this: CrossFit asks a lot of your body. I’m here to argue that Primal eating and living can help you answer. There are many reasons why the Primal Blueprint, in contrast to paleo, can make CrossFitters fitter, faster, and recover better. I’ll just list a few for now:

  1. Primal is a more flexible version of paleo. It’s more malleable, allowing use of some of the most potent foods for recovery from intense training—dairy, whey protein, and dense starchy carbohydrates. Early incarnations of paleo restricted dairy, assuming universal intolerance, and cautioned against starchy plants, assuming everyone was sedentary.
  2. Primal isn’t paleo. Paleo is a great approach to diet for most people. You could do a lot worse than eating animals and plants and avoiding potentially allergenic foods. But the paleo diet people are criticizing is an archaic, narrow version that just doesn’t apply to the Primal Blueprint. As new evidence unfolds, Primal adapts. It’s the only way to stay honest in this business, even if it means dining on crow (which, by the way, is totally Primal) from time to time.
  3. Primal gets you fat-adapted. While the most intense WODs definitely burn through—and require that you replenish—a ton of glycogen, fat adaptation benefits every athlete. A fat-adapted athlete will burn more body fat at any given intensity. A fat-adapted athlete will hold on to muscle glycogen longer, saving it for later. A fat-adapted athlete has more and better mitochondria with the metabolic flexibility to burn fat, ketones, and carbs. And once you become fat-adapted and build those fat-burning mitochondria, they don’t just disappear. You can even eat more carbs, and your muscles will maintain the upregulated ability to burn fat.
  4. Primal is macronutrient-agnostic. My personal flavor of Primal is definitely higher fat and lower carb, but that’s me. That’s what works for my goals and lifestyle. For a top CrossFitter, Primal might be higher carb and lower fat. It’s really up to you and your goals.
  5. Primal is way more than diet. Heck, your average CrossFitter could maintain whatever diet they want, only follow the Primal lifestyle laws, and see huge improvements to their performance and recovery. Sleep, sun exposure, social contact, mental stimulation, circadian health, nature exposure, and other lifestyle factors all have huge impacts on not only your physical health, but also your physical performance.

The primary goals of the Primal Blueprint are to offer information about how various macronutrients, micronutrients, and other food compounds affect your health and performance, and allow—nay, force—you to chart your own course. Some say that’s a weakness, a lack of conviction. So what? Ideological conviction is exactly what we don’t need.

In the coming weeks, I’ll address the common criticisms CrossFitters make about paleo, why they don’t apply to Primal, and how going Primal can actually solve many of the most common issues CrossFitters face.

Tune in tomorrow for the first official post in this series. Thanks for stopping by today, everyone. Have questions you’d like me to take up around CrossFit (or other intensive training program) and the Primal Blueprint? Share and discuss in the comment board.

I’ve never done Crossfit (or anything that intense!) but love how you pointed out the differences between Paleo and Rrimal. I look at Primal as much more of a lifestyle than just a diet. And lol to the term “macro-nutrient agnostic”! I definitely look and feel my best on a high fat/low carb template, but totally believe that some people may need more starchy veggies, etc. I look forward to this series of posts!

Keto and Primal aren’t necessarily each at one end of a spectrum, so I don’t know what gain there is comparing the two really. Keto seems, from what I’ve seen, be more extremely low in carbs than the carb-cure of roughly 100–150g per day that the primal blueprint allows for. Both Robb Wolf (Author of the Paleo Diet and Wired to Eat) and Mark Sission dabble in keto. Depending on your lifestyle, health, activity level etc, strict keto could be either beneficial or detrimental. From what I’ve seen, keto and primal share the concept of regulating blood glucose levels and… Read more »

If I read you correctly, you have the impression that Mark is now advocating Ketogenic diet over Primal; right? Where in fact he is advocating (and that’s what I’ve been doing for a while) cycling between the two, as being ketogenic 24/7 should be reserved to particular medical conditions and a select few. Ketosis is very low carb (0-50 grams), while primal is anywhere from 50-100 with 150 at the extreme, depends on once metabolic health and physical activity. The main source of calories is still the percentage of fat consumed, while protein is fairly constant and it’s the carbs… Read more »

For the weekend warrior, Crossfit is dangerous at best. Too many CrossFit centers offer as the daily workout, routines which include Olympic style lifts. All Olympic lifts should be nixed as Oly lifts require hundreds of hours of training conducted by Olympic lifting coaches. Olympic lifting is a real sport that demands real training. About the worst exercise anyone can do is the behind-the-neck squat as it transfers the load through the spine to the hip joint and onto the knee joints and ankle joints rather than transferring the load through the muscle chain from core to quads, hams and… Read more »

You have not challenged me at all.

Facts remain.

The behind-the-neck squat is a dangerous exercise that is inefficient for muscle stimulation relative to other leg exercises (e.g., weighted step ups, Zerchers).

CrossFitters come across as dopey cultists.

OH my goodness, the “cult” of CrossFit. No, what results is a support system of people who are deeply passionate about what they are doing. There are also “cults” of cyclists and “cults” of runners. Oh, and perhaps the most dangerous of all – the yoga “cults.” Watch out for those because yoga is known to cause tons of injuries, and those people are also religiously dangerous. Sarcasm briefly aside, yoga used to get the bad wrap for causing injuries, and (thankfully?) CrossFit is now getting that blame.

Guys and girls it’s not black or white; there’s a middle and many forms of training that deliver in so many ways then just raw strength. Some excel in CF, some at Calisthenics and body weight training and some find that freeletics works best for them. And then there’s GMB which I was recently introduced to via MDA, where strength is just part of the equation; the others two being agility and body control. Just like there are Olympians that excel at sprinting and others at long distance.

I’m 56 and enjoy CF and most of the people I know in the gym are about the same age. It’s fun, I haven’t been injured and am stronger biking, hiking and paddling because of the weightlifting in CF. I think I have a much greater chance of injury riding my bike on PCH these days. I assume behind the neck squat = back squat; it’s very effective for strengthening your posterior musculature; just do it correctly. Crossfit is not populated with dumb cultists blindly following their trainer. You enjoy your sprints and push-ups, and I enjoy what I do.

Joe Skonue

Behind the neck squat is resting a laden bar on the Images of cervical vertabrae. The load transfers through spine and into the lower joints the through the movement.

Contrast such a poor, inefficient exercise with the Zercher, which transfers the load from the abs into the glutes, hams and quads.

You simply do not know what you’re talking about Kristin.

At 56, good luck wasting valuable training time. You don’t have that many years left.

If that is what you think a low or high bar squat is then you are doing it wrong. You never rest the bar on your vertebrae. The bar rest on your rear delts and traps depending on position. You have a very bad idea of a high bar squat of stupidly putting the bar on that bone behind your neck. You do not put the bar on your vertebrae. Done right the squat is the best exercise you can do. In a properly done squat at proper depth, the weight rests on your shoulders loads on your quads and… Read more »

Feeling stronger, the commraderie of the community, always having a new goal to shoot for that I can share with others who care.

I am in the personal training business and have gone to Crossfit. It is all about the coaches. Good, safe coaches, good safe workouts. Every instructor of any group workout needs to provide safe workouts with modifications for new members and advanced members. Unfortunately, everyone, even those who are very aware of their own bodies, can get injuries.

I did Crossfit for over two years as an older person (late 50’s) and ended up with two permanent injuries, arm (from Death by Pull Ups WOD), and lower back (from Death by Deadlifts WOD). In my demographic I don’t know of anyone who avoided serious injury. Of course trainers always blamed the customer for their injury. Funny how the owner told me to come in more often, and the trainer told me to back off and not do too much. Completely Nuts..

I’m in your demographic. I did Crossift for a couple of years 3x a week, and sustained no injuries. It was great for me, and taught me that physically, I can do more than I think I can. I was outdoing many of the 20 somethings! To this day when I get home from work, I grab my Rx Jump rope and knock out a hundred or so, then make sure I can still lift 100lbs over my hear 5 times, then do squats with that same weight. And now, I’m starting to miss those kettlebells… It worked for me.

Not knocking working out. I love a good workout. But not one that’s fing nuts, like multiple heavy Olympic lifts for speed for 25 minutes, mixed in with other fun and games.

But like they say, it’s “elite fitness”. If you are not elite then Crossfit is VERY likely to injure you, maybe permanently.

There are better options. Watch Ted Naiman’s video on exercise, for example.

I tried it in my early 40’s for 6 months. I found it to be inefficient and I was injured often (heavy kettlebell “American Style” swings for a ridiculous number of reps/rounds). For most people who aren’t slackers, if you put a timer on the workout and keep score, they are going to give it more than their all…unfortunately…but the last straw for me was when I realized after 6 months that no one was really getting better except at insignificant (to me) “Fran” times, etc.

The main difference is that primal man would have listened to his body. They would have slowed down when fatigued and rested when sore (the whole “purpose” of those mechanisms). Serious crossfitters often ignore the signs which is when injury occurs.

But be honest…did you join Crossfit to do the “Murphy” or “Fran” or to maximize your deadlift reps, etc.? No one does. That’s why it’s inefficient and for many, dangerous. And honestly, I never met anyone who did it and went from fat to ripped (or even not fat…and I’m not talking about losing 20lbs but still needing to lose another 20+). They just kinda stayed the way they were physically….but boy did their “Fran” time increase! woohoo! lol

Often times I think the BIGGEST issue with Crossfitters using Primal is that they tend to restrict too much. The flexibility of primal, as pointed out, allows one to eat more food, provided they can “handle” it and eat unlimited quantities. While a lot of the Crossfit community focuses on starches/carbohydrates, there are studies that show overall calories are more important to avoiding certain metabolic issues related to under-eating and over training.

Living primal is a lifestyle with a minimalist approach. It involves settling for what you “need” in life as opposed to “wanting” everything that is convenient. To often we want to be comfortable because it feels good or tastes good at the moment. But the comfort could be death by a thousand cuts such as over consuming gluten, dairy, sugar…..

Chronic cardio anyone? Crossfit would be great if it didn’t require pushing as hard as you can possibly go for 10-15 minutes before being allowed to catch your breath. Major recipe for excess cortisol, which for some types will lead to weight gain or difficulty losing fat. This type of glycogen demand will also make many people eat like crazy a few hours later. There’s a reason why many female crossfitters aren’t very lean, considering how insanely hard they work out and watch their diet.

+1 for a logical approach. I’ve never done Crossfit and don’t plan to. It’s too extreme for the average person. You’re right; it could be a great option if a little common sense is employed. Personally, I’ve never understood the need to push the body that hard, or the reasoning behind it.

This! If Mark says Crossfit is anything BUT chronic cardio, he’s a hypocrite. Because just because they incorporate weightlifting into the WOD, the fact that it is almost always “AMRAP” or for time, etc. by its very nature means it will be a mostly cardio-focused workout. It is chronic cardio if you do it more than once a week (or twice, if super fit).

Their diet is that of most professional athletes (high carb, low fat). And their training is that of a professional athlete (i.e., not Crossfit WODs).

I did a free Crossfit workout at a local box just to see what it was like and it kicked my butt! The brutal and punishing nature of this style of training definitely lends itself to higher carb intake since it’s highly glycolitic. This could easily be accomplished while adhering to primal friendly sources of carbohydrates like starchy tubers and some fruit.
