A variety of experience can help you be a better nude model:
- Gymnastics, dance, and yoga for flexibility, balance and posing ideas
- Drama/theatre/acting for facial expression and body language
- Cheering for on-camera presence and facial expression
- Athletics for general physical conditioning. I’ve photographed body builders, soccer players, softball players, etc.
- Swimming for physical conditioning and aquatic shots
- Pole dancing, not the kind that people may think of, but those who do it for exercise
