CrossFit is a precise combination of exercise and nutrition that has been proven to increase fitness and health for people of all ages and abilities. CrossFit is founded on the first scientifically rigorous definition of fitness: The program produces observable results that can be measured and replicated. You can do CrossFit with a credentialed CrossFit trainer or in a supportive, motivating community at a licensed CrossFit affiliate, or you can do CrossFit in your garage or home gym by studying the resources found on this site

Yes. Everyone can do CrossFit regardless of age, injuries and current fitness levels. The program is modified for each person to help him or her safely become healthier and fitter. Grandparents and Olympians can perform modified versions of the same general workout.

No matter what your current fitness level is, you can start CrossFit. Every workout is infinitely scalable, and designed to help you succeed, improve your fitness, and move you toward your goals

Yes. CrossFit training is very safe, and sitting on your couch is actually incredibly dangerous. In CrossFit boxes, credentialed trainers provide precise instructions and coaching to help people move safely and efficiently, helping people avoid all the diseases that come from inactivity, obesity and poor nutrition.

To accomplish your goals faster, we recommend you eat a variety of healthy foods in quantities that support fitness training but not body fat. By avoiding excessive amounts of refined carbohydrates and measuring your intake of protein, carbohydrates and fat, you will see dramatic, measurable increases in health.

CrossFit holds a uniquely elegant solution to the greatest problem facing the world today: chronic disease. The CrossFit program—constantly varied high-intensity functional movement coupled with meat and vegetables, nuts and seeds, some fruit, little starch, and no sugar—can give you a pass on chronic disease. If you are not sick, know that fitness provides a great margin of protection against the ravages of time and disease. Fitness is and should be “super-wellness.” To improve or preserve your health, do CrossFit.

CrossFit improves general physical preparedness (GPP). We have designed our program to elicit as broad an adaptational response as possible. CrossFit is not a specialized fitness program but a deliberate attempt to optimize physical competence in each of 10 fitness domains: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance and accuracy. CrossFit was developed to enhance an individual’s competency at all physical tasks. People who do CrossFit are prepared for all challenges, whether they come in the gym, on a playing field or as part of daily life.

The WOD is a starting point, and each person will need to experiment to determine what “enough” means. Experienced athletes with specific competition goals might need additional work to improve their fitness, while beginners might need to reduce the volume of the WOD to optimize results. The exact amount of work can be determined with the assistance of an expert coach at a CrossFit affiliate or by carefully logging your workouts and evaluating the results. The demands of sport and active living will affect what you can do in each WOD, and you will need to balance your work/rest cycles to allow for recovery. In general, if you only do each day’s WOD, you will find yourself at an improved level of fitness.
