I guess it's kind of like saying, "What is 'reading'?" Is reading when you can get through "See Spot Run" or is reading when you can read "Moby Dick?" Is it practicing your spelling or is it flying through your favorite fiction novel without a thought to the act of reading? Or is "reading" all of those things and everything in-between - failed, succeeded, attempted, and dreamed. If that's the case, then it's all CrossFit. It's CrossFit when my mom does it and it's CrossFit when Kristan Clever does it.
Crossfit is scalable and can be modified to any fitness or skill level. To people who might have mobility issues or have an injury. For beginners building strength and endurance to be able to do what the people who have been crossfitting for 2 or 3 years can do. So remember this the next time you are using a band or a lighter weight than the person beside you. Everyone started out at that level and the harder you work the faster you will improve and get up to that same level.
