I own exercise DVDs and must admit I never use them regularly - although I should.
I have an ab-trimmer but it's gathering dust in the loft.
My friend has a running machine which she uses every day (well she is training for the London Marathon!) and I keep thinking about getting one for myself. Thing is it will probably just end up sitting in the corner unused after a while.
Interested to hear what others have, what makes they are etc etc.
