"KMF Crossfit is hands down the best box I've ever been in!! The staff are incredibly knowledgeable and always eager to help and answer any questions you have about the WOD, form, nutrition, etc. They also place a huge emphasis on safety (you have to take 10 beginner fundamental classes when you join), which a lot of Crossfit gyms don't do enough. However, if you're experienced when you join you can test out of some/all of the classes. The workouts are always challenging and the staff encourage and push you the entire time. I LOVE this place -- I get sad every time I have to miss a day!! Would very, very highly recommend this location to friends and family"

What is Crossfit exactly?

CrossFit 101

The CrossFit prescription is “constantly varied, high-intensity, functional movement.” Functional movements are universal motor recruitment patterns; they are performed in a wave of contraction from core to extremity; and they are compound movements- i.e., they are multi-joint. They are natural, effective, and efficient locomotors of the body and external objects, but no aspect of functional movements is more important than their capacity to move large loads over long distances, and to do so quickly.

The CrossFit program is designed for universal scalability, making it the perfect application for any committed individual, regardless of experience. We’ve used our same routines for elderly individuals with heart disease and cage fighters one month out from televised bouts. We scale load and intensity; we don’t change programs.

The needs of Olympic athletes and our grandparents differ by degree, not kind. Our hunters, skiers, mountain bike riders and housewives have found their best fitness from the same regimen.
