I just started at the gym and was all gung ho for a month and lost 2kg. But my legs were killing me, found out I have shin splints. I didn't even run or anything just walking on the treadmill and bike nothing high impact. I am about 15 kilos heavier than I want to be so now I am going to try swimming but have heard that swimming is not good for weight loss? Has anyone has success with swimming? It is either that or starvation!!!
