"Lifting and carrying bags of groceries, pulling down your suitcase from a train’s overhead luggage rack, bending down to pick something off the floor, or climbing stairs are all examples of 'functional movement' we all do daily. CrossFit™ aims to provide opportunities for people to prepare themselves to tackle these functional movement needs. ... CrossFit™ is training everyone, young and old, to stay healthy, well, and engaged with the world around them. The program is 'infinitely scalable,' meaning prescribed workout patterns (weights, movements, etc.) can be changed to accommodate the needs of anyone, regardless of age, who wishes to participate."
