Young dancers are training at a very vulnerable time in their lives... So train the whole person, not just the dancer.
Deborah BullI always recommend a sensible diet, including lots of carbohydrates and avoiding too much fat. Dancers don't need different fuel from other people - they just need more of it because they use more energy.
Deborah BullYou increase muscle bulk by training against resistance. For example, weights. And in ballet, this isn't the case.
Deborah BullI get to the theatre in plenty of time; I prepare my shoes in advance; I eat and drink the right things at the right time. The rest you have to leave to luck!
