**AMRAP:** As Many Rounds/Reps as Possible. This metric challenges you to complete as many rounds or reps of a workout as possible within a set time frame.

CrossFit Time Domains

CrossFit workouts can be categorized into different time domains, each targeting different fitness components:

Short (<1 min): High-intensity, power, and speed workouts. Examples include sprints and heavy lifts.

Medium (1-5 min): Moderate-intensity workouts that build endurance and capacity. Examples include AMRAPs and longer metcons (metabolic conditioning).

CrossFit Energy Systems

CrossFit workouts target three primary energy systems in the body:

Phosphagen (ATP-CP): The immediate energy system used for short, intense efforts like heavy lifts or sprints.

Glycolytic (Anaerobic): The energy system used for longer, high-intensity efforts like AMRAPs or longer metcons. It produces lactic acid, leading to muscle fatigue.

CrossFit Community and Culture

CrossFit's community is one of its most appealing aspects. Here are some terms that describe this culture:

**Box:** A CrossFit gym. Each box is independently owned and operated, offering a unique atmosphere and programming.

**Whiteboard:** The board where the WOD, scores, and other relevant information are posted. It's a central feature of every box.

CrossFit Competitions

CrossFit hosts various competitions, from local throwdowns to the prestigious CrossFit Games. Here are some key terms:

Qualifier:** A workout or series of workouts used to determine which athletes advance to the next stage of competition.

Finals:** The final stage of a competition where the fittest athletes compete for the top spots.

Now that you're equipped with the lingo, you're ready to dive into the world of CrossFit. Remember, everyone starts as a beginner, so don't be intimidated by the terms or the intensity. Embrace the community, scale the workouts as needed, and enjoy the journey to becoming a fitter, stronger version of yourself.
