• Beginners to weight training: If you have never weight trained before, CrossFit is a great place for you to start, provided you have a great coach.
• People looking for support and community: Every CrossFit gym has a really tight-knit community feel to it.
• Fitness fanatics: The general protocol is 3 days on, 1 day off, but many CrossFitters end up at the gym more frequently. 
• Masochists: You’ll often be in situations where you use all your effort to finish a workout and continue to push yourself beyond.
• Former athletes: You get to compete with people in your class and go online to see how you did against the world’s elite CrossFit athletes.

• Specialists: CrossFit prides itself on not specializing.
• Sport-specific athletes:  CrossFit won’t improve your specific sport skills unless you are training for those specific sport skills.
• Solo trainers: CrossFit is group training, which means you won’t have that opportunity to get your stuff done on your own.

• You’re often told to complete a number of strength training or endurance exercises as fast as possible. It’s really easy to sacrifice form in exchange for finishing the workout quicker if you don’t have somebody spotting you.
• It attracts folks who push themselves so hard they actually do bodily harm.
• A very small portion of CrossFitters can push themselves so hard, their muscle fibers break down and are released into the bloodstream, poisoning the kidneys. The medical condition is called rhabdomyolysis.

The usual structure:

• Introduction class: Usually there’s a quick overview, then a basic bodyweight movement workout, and then they talk to you about joining.
• On Ramp/Elements: The purpose of these is to teach you the 9 foundational movements of CrossFit and all about proper form. 
• Regular classes: It takes anywhere from 45 minutes to an hour. Everybody starts at the same time, there are instructors walking around helping out and keeping track.

Most CrossFit gyms will split their classes into 3-4 sections:

• Dynamic warm-up: Functional movements, stretches, and mobility work that compliment the movements you’ll be doing in the workout that day.
• Skill/Strength work. 
• WOD – the workout of the day: you’ll be told to do a certain number of reps of particular exercises as quickly as possible, or you’ll have a set time limit to do as many of a certain exercise as possible.
• Cool down and stretching.

Breakdown of what you may see from coaches:

• CrossFit Level 1 – an ANSI-accredited certification. The person attended a weekend-long course and passed the exam.
• CrossFit Level 2 – It involves far more in-depth training in coaching.
• Certified CrossFit Level 3 Trainer – Coaches who have passed both the Level 1 & Level 2 certification courses as well as a CrossFit-specific exam.
• Certified CrossFit Level 4 Coach – The highest certification level available.
• Specialty Seminars – These are one- to two-day courses on specific topics.
• Other non-CrossFit certifications.
