Kellie Davis became enthusiastic about fitness and training when she started working with a trainer herself several years ago in San Diego. At the time she was experiencing her own struggles with losing weight and staying fit. Because of the time with her trainer, she lost nearly 30 pounds and changed her life for the healthier. Having had great success, she was motivated to learn more about fitness and nutrition and eventually became certified as a personal trainer in order to help others struggling to reach their fitness goals achieve success in overcoming their own preconceived limits. Outside of fitness, Kellie enjoys running, swimming and scuba diving.

Shaghig Kodbashian
has played sports all her life and is currently an avid and passionate rock climber. Her personal experience with four knee surgeries has provided her first hand knowledge of what it takes to recover from injury/surgery and come back stronger than before. Shaghig's style of training incorporates strength and cardiovascular exercises, with a focus on core and balance. She likes to create unique exercises that engage the large muscle groups, while equally activating the small ones. Her focus is on total body.  In addition to using conventional weights, she utilizes TRX suspension training, which uses your own body weight, for a total body workout. She wants to make working out fun and challenging at the same time. She believes that we all have the strength and ability to push a little more than what we may think we're capable of….but all in good/safe fun!
