help please!.. advice for fitness

I need to get more excercise into my life and I want to buy something I can use at home. I've seen a piece of equipment called a lateral thigh trainer, which works quite a lot of areas in the body. Can anyone confirm this, or suggest another piece of equipment I can use at home, which is not too bulky, complicated, or expensive, and will give me some good all round excercise? I'd be grateful for any help. Tweet
