Go to any bar with live music at night in Belize, and you will witness the dominant form of Belizean dancing, which like the dominant form of Belizean music (Punta rock), originates from traditional Garifuna culture. That is, it involves shaking your arse. Visitors to Belize often marvel at how Belizean women especially are able to “move their ass completely independently of the rest of their body”, and think that they have developed special arse muscles that allow such frenetic yet well-controlled booty manoeuvres.
I have a secret to share: no special arse muscles are involved. In fact, I would venture that you don’t really use your arse muscles at all. Or even your waist muscles (not at beginners’ level punta/punta rock dancing anyway). The key is all in the feet and legs. If you stand still, feet shoulder width apart, bend your knees slightly, and then bend one knee more than the other, you will find your other knee straightens. Then you switch and bend your other knee forward more. Keep doing this, and you will find a funny thing happens: your arse moves side to side. No special arse muscles required.
Of course, to look professional, you have to do it in time to the music, and be able to move around side-to-side, forwards, backwards, in a circle, and a few other little fancier movements here and there, but that is the basic secret. So stop focussing on your arse, shift your knees, and be prepared to look like an idiot.
Ray likes to take credit for the fact that I can now dance punta (and paranda, and to a certain extent hungu-hungu), and while he did give me two or three lessons (where even though it was just me and him in the house I still felt like a complete idiot!), I think most of it just came from getting bored sitting down watching everyone else having a good time, and finally thinking “ach stuff it who cares” to all those that wanted to laugh at the white gal who (couldn’t) dance.
