CrossFit is the principal strength and conditioning program for many police academies and tactical operations teams, military special operations units, champion martial artists, and hundreds of other elite and professional athletes worldwide. The program delivers a fitness that is, by design, broad, general, and inclusive. CrossFit's specialty is not specializing. Combat, survival, many sports, and life reward this kind of fitness and, on average, punish the specialist.
The CrossFit program is designed for universal scalability making it the perfect application for any committed individual regardless of experience. The same routines are used for elderly individuals with heart disease and cage fighters one month out from televised bouts. The scale load and intensity are just adjusted; there is never changing of the program.
These are timed exercises where you are competing against yourself. They range from 20 minutes to an hour depending on where you go. They are usually located in a warehouse type of building. Not a lot of glamour, no tv's and always smells like sweat!
So if you want a down and dirty work out that will get you into AMAZING shape super quick, this is it. Find a crossfit gym near you. They are popping up all over!
Have a very fit day!
