I work at 24 Hour Fitness in Houston... we have 30 gyms in the area... yes, I use the gym for personal training, and yes TFN stuff will be worn! I hope they carry the performance fabrics though... moisture wicking is the bomb! I hate cotton now that the performance fabrics are out.
By the way, I will turn people on to where they can get TFN stuff... I hope to impact the area.
