The Immune Building Mood Boosting Workout Was Just What I needed! It Challenged Me to get moving and jumpstart my workouts right in my home. Coach Tracie is knowledgeable and skilled in fitness and nutrition. She made me feel comfortable and offered modified movements when they were needed. In a short amount of time my heart rate was up and i could feel the burn. I’m on week two and looking to make this a regular part of my fitness program.
