I exercise every morning. I do light weights - 5lb and 10lb arm exercises - and then lie and lift my arms and legs. It's all about keeping core strength. I do a lot of stretching too.
When I sing I feel like when you're first in love. It's more than sex. It's that point two people can get to they call love when you really touch someone for the first time but it's gigantic multiplied by the whole audience. I feel chills.
