"CrossFit is not a specialized fitness program, but a deliberate attempt to optimize physical competence in each of 10 recognized fitness domains," says founder Greg Glassman in the Foundations document. Those domains are cardiovascular and respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy.[33]
By the end of my first Whole30, I had an entire document full of recipes I still wanted to try, which motivated me to keep going. Yes, you can stay compliant by eating steamed chicken and lettuce every day, but why would you do that to yourself? "Find foods that are easy to make and that you enjoy eating," Cohn says. "If you eat foods that you don’t like just to follow the diet, you are not going to continue to eat those foods once you are done with the 30 days." Pro tip: Google the Whole30 version of your favorite meal, there's probably a recipe out there for it. (Unless that meal is cake.) This really helped reignite my love for cooking and encouraged me to continue preparing my own meals, instead of relying on Seamless delivery.

Due to CrossFit's official partnership with Reebok, competitors at the 2015 Games were banned from wearing Nike footwear.[32] Nike arranged for several trucks to be parked near the main entrance to the arena, which served as mobile billboards with the slogan "Don't ban our shoe, beat our shoe".[33] The partnership also prohibits Nike from labeling its Metcon shoes as intended for CrossFit – the brand uses the term "high intensity training" instead.[32]
Re: “Too old masters’ age group”… I have zero insight as to whether or not this will happen, but I’m a betting man & I’m putting my money on yes. If CrossFit lasts, which I think it will, I believe they’ll continue to evolve as the sport grows in size and age. It’ll come down to how many “too old” athletes end up being serious competitors. You’ll lead the way.

Trying to devise an ideal diet by studying contemporary hunter-gatherers is difficult because of the great disparities that exist; for example, the animal-derived calorie percentage ranges from 25% for the Gwi people of southern Africa to 99% for the Alaskan Nunamiut.[39] Descendants of populations with different diets have different genetic adaptations to those diets, such as the ability to digest sugars from starchy foods.[39] Modern hunter-gatherers tend to exercise considerably more than modern office workers, protecting them from heart disease and diabetes, though highly processed modern foods also contribute to diabetes when those populations move into cities.[39]

Why so strict? According to the diet's founders, Melissa and Dallas Hartwig, these are the foods that are most likely to cause inflammation and gut damage. They're also the foods that the founders say destabilize blood sugar levels and lead to cravings. But it's hard to say whether that's true for everyone. In general, limiting sugar and alcohol is always a good idea. But dairy, grains, and legumes? They don't trigger an inflammatory response in everyone, Haas says.

One larger randomized controlled trial followed 70 post-menopausal Swedish women with obesity for two years, who were placed on either a Paleo diet or a Nordic Nutrition Recommendations (NNR) diet. [7] The Paleo diet provided 30% of total calories from protein, 40% fat (from mostly monounsaturated and polyunsaturated fats) and 30% carbohydrates. It included lean meats, fish, eggs, vegetables, fruits, berries, nuts, avocado, and olive oil. The NNR diet provided less protein and fat but more carbohydrate with 15% protein, 25-30% fat, and 55-60% carbohydrates, including foods similar to the Paleo diet but also low-fat dairy products and high-fiber grains. Both groups significantly decreased fat mass and weight circumference at 6 and 24 months, with the Paleo diet producing greater fat loss at 6 months but not at 24 months. Triglyceride levels decreased more significantly with the Paleo diet at 6 and 24 months than the NNR diet.
After spending a week fine-tuning my new eating plan, I decided to add workouts back into my routine. On a typical week, I'll go to a cardio or strength class (I like boxing) once or twice and do some yoga or stretching at home another night. I dove right in and hit up my favorite boxing studio, Rumble. But I was really nervous. What if I didn't have enough energy? What if I passed out during class? What if I got so hungry I caved and bought a slice of pizza on the walk home from class?

CrossFit gyms use equipment from multiple disciplines, including barbells, dumbbells, gymnastics rings, pull-up bars, jump ropes, kettlebells, medicine balls, plyo boxes,[23] resistance bands, rowing machines, and various mats. CrossFit is focused on "constantly varied, high-intensity, functional movement,"[24] drawing on categories and exercises such as calisthenics,[25] Olympic-style weightlifting, powerlifting, Strongman-type events, plyometrics, body weight exercises, indoor rowing, aerobic exercise, running, and swimming.[26]
