When it comes to any other service, you will look at the providers credentials, experience, and reputation. But, for some ungodly reason, people don't look for the same thing when the join a gym or hire a personal trainer.
Go to any Globo Gym, and the person training you has little or no training, except in the art of upselling you to more personal training sessions. And... this is the kicker... if they do have any training, it is done by their own "in-house" group of experts, who are poorly or partially trained at best.
If you go to CrossFit Koncepts you will have a completely different experience. The Training Director, Michael Krivka, is a Master RKC (Russian Kettlebell Certified) Instructor, with over twenty years of experience teaching and training with Kettlebells. On top of being the author and co-author of several books, he is also a training consultant to a number of Law Enforcement agencies (locally and nationally), as well being a SME (Subject Matter Expert) for the Navy and Air Force, as well as working with the FBI, DEA, Secret Service, and other agencies, for over 35 years.
CrossFit Koncepts also has the most RKC and HKC (Hardstyle Kettlebell Certified) instructors in residence than any other training facility in the world. This means that you will be able to get training advice and instruction not only from Michael Krivka, but from many of the people in the classes you will be attending. This knowledge rich environment guarantees that you will have a great training experience as well as a benefit deep learning environment.
So... you could pay a lot less, or you could pay a lot more. But at least at CrossFit Koncepts you will know what you are paying for!
