Our daughter has been to this gym and another. We prefer this gym because they focus on doing everything correct and not moving on till it is done correctly. At the other gym she learned how to do a lot of things incorrectly. She now has to unlearn her skills she learn incorrectly. We are very impressed with Nikolai. He has helped our daughter improve tremendously. This gym is a great value and my wife and I are very pleased with our daughters improvement.
