Been There, Done That!
I am a mother of 2 girls born in 2001 and 2007 and have successfully lost over 50lbs… two times! I use my experience as a bodybuilder, model, and mother to design my workouts, encourage my clients and continue to motivate others to change their bodies with fitness and real solutions! But, how did I get here? Read on below…. 

Born to Train
I have been involved in fitness my entire life. As a preschooler I remember watching my mother work out at home. In grades chool I enjoyed trips to the gym, even if it was only to the childcare area, and always looked forward to the day I was old enough to join in on the action. In middle school, I loved exercising to workout videos and walking outside. In highschool, I finally got a job at the local gym in Brentwood and began bodybuilding.

Start of a Career
As a senior in highschool I became a personal trainer at that gym and showed members how to use the equipment. The summer after highschool graduation, in 1996, I earned my personal training certification and began training clients in their homes in Brentwood almost immediately.                                                                                                                                      

Excelling at a Passion

Swimsuit pageants led to an additional career of promotional modeling for companies like Stacker 2, and wh
ile living in Tampa Bay, FL I became a regular guest and Fitness Expert on HSN (The Home Shopping Network). During this time, I owned and operated a fitness studio in FL. It was there that I began developing my Weight Loss Boot Camp. Since moving back to Tennessee at the end of 2008, I started Niki G's Fitness Boot Camp which now offers 4 locations in the Nashville area and over 50 classes a week.
