I have to tell everyone that I attended the TRX cert. at Asphalt Green in NYC. Absolutely amazing!!!! Like many of you I have been in this industry for many years and have attended many many conferences, seminars, and certifications. This one ranked up there as one of the best. The amount of information is overwhelming which is the way I like it. To many times the certs. are filled with fluff and maybe a few cool tips and new exercises. This one has enough ideas to reinvent any trainer that is looking to spice up work outs. I already am applying just a few of the pricipals and exercises that I learned and the client feed back is extremely positive. If you are looking to learn from two of the best in the biz, then attend any course given by either Chris or Jonathan who lectured in NYC. Two of the most energetic and intelligent guys I have seen. Talking about professional? I can't say enought about them. Just go.....Listen and learn and you will see. If you can't then this is the wrong biz for you.....Enough said! Thank you to denise as TRX for recommending me to go....
