I agree with Karin’s last sentence because that is the most important part of being a fitness instructor, coach or personal trainer. In my opinion many instructors today are trying to incorporate every new trend they see online or out there without knowing to much about it or if it works for their clients/participants. If you are good at what you do then there is little or no big hurry to switch or add something that might or might not work. Just because there is a new trend out there it doesn’t mean it’s the silver bullet of the industry. You can read about them and test all the new trends that are coming out to see if they will be suitable for your clients and if they are safe and effective to use. Then add it to your experiences/methods of training and use it when needed. Personally I wouldn’t worry to much about it, but I’m not in your shoes. The problem today with our industry is that everyone wants to do and offer everything out there and then nothing gets done the right way.
My point is that not everything out there is as good and as great as they sound and before you copy or add to your arsenal of methods something new, make sure you have done some research on it and it’s worth your time and money. I hope this helps.
