I have three stone or so to lose after my DD. I walk for an hour a day and do ten minutes rowing machine. Assuming I am watching what I eat (which I am) - is this 'enough' exercise? I have PCOS which makes it difficult to lose weight, but really, what ought I to be doing? Walking is good as I have been told 'slow burn' is good for PCOS sufferers, and also I enjoy it. Any tips? Should I be doing some weights as well? (I have bought a few hand weights and I also have a trampette, but don't really know what do do with 'em!) All tips welcomed...
