What do people love about it?
CrossFit classes are high-intesnity group classes focused on the philosophy of high-intensity interval training or HITT, the belief that more intense exercise in a shorter amount of time is more effective.
CrossFitters are also part of a unique culture and philosophy. Many CrossFitters follow a specific diet, namely the Paleo Diet, and are fitness fanatics or former athletes who thrive off of competition and a team atmosphere (but that doesn't mean nonathletes can't reap the CrossFit benefits).
CrossFit addicts love the communal environment of this workout regimen and appreciate the verbal encouragement and support that they gain from their teammates and coaches while they exercise.
Sometimes criticized for just how intense the workout can be, CrossFit teaches its followers to accept discomfort, push your body to its limits and therefore bring yourself to a place of maximum impact. CrossFit operates off of the belief that you should train your body for the unknown and be physically prepared for almost anything.
While this philosophy may be intimidating to some, it is inspiring and motivational to its followers.
