CrossFit Inc. is a fitness company founded by Greg Glassman in 2000.
CrossFit, is a strength and conditioning program with the aim of improving, among other things, muscular strength, cardio-respiratory endurance, and flexibility. It advocates a perpetually changing mix of aerobic exercise, gymnastics (body weight exercises), and Olympic weight lifting.
Each 'workout of the day' (WOD) is treated as a competition where you try to beat both your workout partners and your own personal best. This keeps competitive people interested and also ensures that individuals are making progress from one workout to the next. Because of the competitive nature of both the community as well as the program, people are also pushed to work harder than they may on their own, yielding more benefit from their workout sessions.
