From the Adidas web site:
From the moment she wakes up until she goes to sleep at night, Patti Zhou has ballet on her mind. In between, you’ll find her training, at least four hours of ballet class every day. Plies, tondus and pirouettes: it’s a routine she’s honed over time through hard work and dedication.
“You have to treat your body like a machine,” says Patti. “If you don’t give the machine fuel, it’s not going to run. I think a healthy, balanced diet is really important – and especially lots of sleep so your body can recharge and recover for the next day.”
