Yvette is a huge proponent of yoga, as it helps her to stay flexible and manage stress - two things that are very important for someone of her occupation and... talents. She tries to set aside at least an hour each day for stretches and meditation, either at home or at the gym, depending on what her schedule allows.
Of course, even her most subdued workouts tend to attract a lot of stares from both men and women alike. Yoga wear is known for it's elasticity, but even the stretchiest garments often find themselves tested to within a gasp of bursting by Yvette's ample (and expansion-prone) curves.
I'm beginning to suspect she buys her sports-bras in bulk.
