Hi Jodie,
Welcome to Social Slimmers.
What kind of workout? You could go running outdoors or get DVDs such as the 30 day shred. What areas are you targeting if specific.
Sainsburys have a lot of exercise goodies on sale at the moment if you live in the UK.
What about your local leisure centre like Belle said. You can join a gym who will give you a programme to follow and they will also do classes (do either or or both?).
