Not really sure how this all works but oh well! I am very unfit, overweight and want to change my life. May seem small to some but i was doing no exercise at all. I began three weeks ago walking at least 5k 6 days a week (which was enough to get a good sweat up for me). I thought i would start ct5k. I have done my first two runs and i really struggle. Am i too unfit to do this? I do manage it (just) and feel wonderful afterwards but not sure its getting any better, next week i have to run for 30secs longer (doesnt seem like much) but im not sure i can do it. Im still doing the runs and walking 6 days a week at least 5k and have changed my diet for the better. Can anyone suggest anything? Any other exercises i could do? Also not seeing much change on the scales and i get very disheartened. I have no idea about all this stuff..literally been a couch potato all my life.
