Salsa is a LATIN dance and it's GREAT for stamina and cardio. There's a lot of MOVEMENT in the core area and so I FEEL like it's AWESOME for sculpting your obliques and your back and just getting that area moving in general.
When you wear the costumes in a period drama, you already feel like a different person - the CLOTHES make you stand differently, CHANGE your posture, the way you walk. You really have to have STAMINA - you have two hours in hair and MAKEUP, and then another hour to remove all that.
What's FUN about chefs is that they're big guys, OFTEN, and they might not look like the most ATHLETIC people, but they're very powerful people, and they have tremendous stamina... It takes a toll on their BODY, too.
