Amy has not only helped my loose weight, but she has given me the support and encouragement to be my very best; mentally, emotionally and physically. Working with Amy is a no-excuses zone and she knows how hard to push me, while still giving me the encouragement to work even harder. Amy’s workouts are individualized and challenging. She not only helps me set goals, but she has helped me meet and exceed them! My energy level and confidence has increased ten fold, and I FEEL AMAZING!
