Circular training system
Crossfit is one of the most popular training systems based on the principles of circular training using functional exercises - exercises that are as close to natural movements as possible.
In the crossfit training system, activities such as interval run, rowing in the simulator, jumping rope, rope climbing, ring and bar exercises, strength exercises using weights, bars and heavy objects are combined.
How are the crossfit workouts built?
Each lesson is a combination of the above activities, bearing the name Workout of the Day( WOD).There are several hundred such combinations, and, in fact, the daily crossfit training is not repeated, and there is no clear system.
One of the distinguishing features of the system is the work in groups of 10-15 people, which helps to train more effectively - experienced community members encourage newcomers, and also compete among themselves for the best result.

Opinions of professionals
Dr. Stuart McGill, University of Waterloo : "The benefits that you can get from a crossfire are crossed out by the risk that you yourself are exposed to, performing inherently dangerous exercises with bad technique and infast pace ".
Chris Shugart, fitness professional: "In fact, the structure of crossfire programs is extremely chaotic, and I do not see any logic in choosing exercises and their sequence. The system can be extremely dangerous for untrained trainers "(5).
Reebok commercials, literally giving the crossfit the label "sport for all", forget to mention the danger of such training for untrained beginners. Not to mention the fact that the system of crossfire is not suitable for a set of muscle mass.
