The girls need to wear her socks for days and get them quite wet and sweaty so they can use those socks to wrap them on their noses and train their breathing like this. You will train with them, they will lend you their sweaty socks so you can put them on your face and breath. Not only you will get stronger, but you will have an awesome time smelling her sweaty socks and eventually their wet and warm soles.
