What is Crossfit?

Circular training system

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.

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.
