When I watch her dance I am reminded that a big layer of fat over the chest and abdomen prevents free movement of the core. That is, she can't bend her body in the middle or pivot at her waist because of the fat layer inhibiting movement.
It's a reminder not to let that happen to my own body. And I hope she can lose some of that layer dancing because it is very unhealthy.
It's hard to imagine her doing a sensuous samba without being able to move from the waist.
