CrossFit is defined as “constantly varied, high-intensity, functional movement.” This means that each Workout of the Day (WOD) is devised to challenge you to use your everyday movements at a fast pace. The workouts are short and always changing so you constantly work all of your body without monotony. WODs are timed or scored to help motivate you and to be measurable; you will be able to see a time or score improvement in a particular workout when it is repeated at a later date.
CrossFit mixes elements of Olympic Lifting, Gymnastics (Body Weight Exercise) & Cardio. One of the things an athlete will notice is an improved overall fitness just from taking part in the WODs.
