Guzmán never skips her workouts. "I do 40 minutes of elliptical, abs, arm, leg, Pilates, and the shows on the weekends," she says. "I drink a lot of water."

Guzmán performs a series of stretching exercises before every performance. "Flexibility can improve your strength and performance in physical activities," says trainer Jacqueline Kaminski. "The goal of flexibility is to have control of your muscles in a full range of motion. So, improving your flexibility is also improving your strength! Furthermore, if your muscles are sore or stiff you may not be able to engage in explosive movements or perform as well during your training."

Guzmán is still recovering after suffering injuries that made it difficult for her to walk. "Being with my daughter is what makes me the happiest, it makes me feel good," she says. Sometimes you don't value things until she loses them, and I have given priority to my health, because without it you can't do anything. When you get a prosthesis you must stop walking and then learn to do it again with a walker and cane; right now I jump, jump and do pirouettes again. I'm happier, it's good that I wear my hips out from dancing, and I can't stop doing it."

Guzmán's performances include plenty of dance, which is a cardio workout in itself. "By consciously putting your body in motion, you're offering yourself a 360-degree physiological reset, which can be cathartic, deeply transforming, and healing," says choreographer and artistic director Kristin Sudeikis.

Guzmán says she likes being taken out of her comfort zone when it comes to her artistic life. "I am a sensitive person, but strong; I describe myself as someone who seeks to be happy, likes creation and art, producing ideas and touching people's heartstrings," she says. "That's why I was born, to transmit sensations. Music is magical, it frames moments in your life, you choose it because it identifies you. I always tell people: 'Do what you like.'"
