Fortunately my Zumba teacher friend Brenda supplied the solution in the form of a FitSteps session at the Grampian Club. FitSteps is the brainchild of Ian and Natalie of 'Strictly' fame - and boy! is it a good workout. Give it a go, if you get the chance. Makes Zumba look sedentary.
The other day, one of my yoga students asked me what I meant when I said, 'See if you can feel where your energy is focused.' Good point. Right now my energy is focused in my feet. They are still tingling after the dancing, despite a shower and a meditation session. I trust that this is a good thing.
