Step dancing and aerobics give me a really good buzz at the end of a stressful day. I’ve been dancing since I was a child and just over two years ago, when I started nursery teaching, I took up step. I go to a gym near my home in Wolverhampton and I also go to an exercise class at the local church hall twice a week. The hardest part is getting myself motivated.

Dressed in black leggings, a T-shirt and white trainers, I do half an hour’s step and half an hour of callanetics (stomach exercises). We exercise to music, usually something upbeat like “Steppin’ Out, Steppin’ Out” or “Dancing on the Ceiling”. It’s a nice crowd - girls only - ranging in age from 16 to 65, who have all sorts of different jobs and come after a hard day’s work.

When I first started going I ached afterwards, but not now. At the end of the class I feel so good it’s unbelievable.

I come home red and sweaty, but tingling, and have either a quick shower or a nice relaxing bath with floating candles in it. I listen to Kenny Gee playing the saxophone and I forget all my problems.
