About Christina Shepherd

I'm Christina, and this is my story.

I am a strength and conditioning specialist as well as a physical therapist helping you build a stronger core and body to prevent injuries and feel good in your skin. I started my fitness journey unhappy with my body, lacking confidence and always just chasing a number on the scale. I made mistakes along the way, and I'm here to prevent others from making the same ones I did. You don't need hours in the gym to see results. You need effective workouts that maximize your progress every time you do them. Elevate your strength and ignite your confidence: That's the name of the game.
