LIFNG is comprised of a team of fitness professionals who care about fitness.

"I started LIFNG with an idea of bringing fitness professionals and fitness enthusiasts together to share their enthusiasm for the fitness industry. Our vision and mission remains grounded in providing fitness professionals with the proper tools and instruction so that they can gain and maintain viable careers in the fitness industry as well as provide their clients with safe instruction. It has grown into so much more than a support group. This is LIFNG."
