I recently had a chance to interview Dr. Derek Ochiai about CrossFit, a workout that has had a huge surge in popularity.
What contributes to the appeal of CrossFit? Workouts are intense, but relatively short in duration, so that it can be more time efficient than some other forms of exercise. Since exercises typically are done in a group setting, there is a sense of community and encouragement while doing these exercises.
What hazards does it pose? Because CrossFit has that sense of encouragement and community, that can also lead to external pressure on the participant to push "beyond their limits", especially when someone is just starting out. If one is going from a relatively sedentary lifestyle to trying to get more fit, that person may not know the difference between "being sore" and actually injuring themselves. Injuries such as tendonitis and muscle strains are common. Also, because someone can fatigue but then go straight to another activity (such as pull-ups), I have seen more traumatic injuries, such as rotator cuff tears of the shoulder and broken bones.
