I know the feeling.. i am in pretty terrible shape as well so i started running again about a month ago.. I must be getting old because my knees started aching pretty bad so I cant run daily anymore, only about 3 times a week.. However on the days that I run I also usually skip a meal or 2 also and then I really feel like I'm actually loosing weight, not just waisting my time lol.. fasting is amazing for the body and so underrated. If u really wanna loose weight fast you should look into it.. 😉
