This is my first post on here. I am just about to start week 4 of couch to 5k. I also do slimming world but I’m struggling to lose the weight and have started to become obsessed with it. I’m 5ft 1 and weigh 10st 2 and I seem to hover round this each week by losing 1/2lb and gaining 1/2 the following week. I run 3 times a week with a days rest in between as recommended by the app but should I be doing more exercise such as swimming or something or have the rest day ready for my next run?
