I'm new here and starting to climb the weight loss mountain! I managed it 15 years ago and lost 5 stone but guess what!? 3 stone are back on again! Our life style changed and my routines went out of the window. Our gorgeous G'Kids are our priority...we look after them 5 days a week.... but it does mean I'm nibbling and not exercising as rigorously as I used to. At 70, I now have severe (and painful) arthritis in my knee and am in line for a knee replacement and feeling very old! So my priority is to get as fit as possible before the op or incur the wrath of the surgeon for wasting his time! Please help!
