"Training with Christina over the winter was a game-changer for me. She quickly identified my lower back weaknesses and designed a workout plan that not only strengthened but also protected that area. Her deep knowledge of body science helped me understand what truly mattered and where to focus my efforts. Beyond her expertise, Christinas's bubbly, supportive, and fun personality made every tough session enjoyable. I always left our workouts feeling motivated and excited to come back and push harder."

But more than that, she is also a wonderful person who is always bringing new ideas, a sound scientific outlook for those interested, and a lot of energy and enthusiasm to every session. I highly recommend her for her well thought out training sessions, unbiased opinions and insights, and above all the fun and giggles that naturally come with her.”
