Carrie Underwood, the 39-year-old singer, has shifted her workout goals over the years. Previously focused on being a certain size, she now prioritizes strength, energy, and longevity. After consuming only 800 calories a day following her American Idol win at age 22, Carrie realized her approach was unhealthy. She now understands the importance of balance and taking care of herself. She listens to her body's needs and adjusts her lifestyle accordingly. Carrie is dedicated to staying fit year-round and incorporates exercise into her everyday life.
