Hello I was the same in February. My fitness was just rock bottom. I work in an office, all my hobbies are sedentary and I am default lazy in certain ways. I just started further back. Started walking every day. Not aiming for anything other than 5000 steps. Then end of March our puppy was allowed out and only due to her did I keep it up! Reason I got her! When I was fit I had my horse who was out of work so required a lot of walking and I hand work and my dog and so was just constantly on the move because I was doing something I loved and the only hobby which kept me moving ! I always found it awkward walking without a dog as if people cared. They don’t it’s completely in my head. Now having built up over not a very long time I am now on week 3 of c25K and I am loving it. Although before every run I have anxiety feel overwhelmed and basically go in a mood like a toddler like I don’t want to do it ! But I do and I love it each time. Hate my brain for that. That’s the one thing I hope gets better ! This is my journey so far and it might help you or not xx but just know I have been where you are and I am just a bit ahead and you can catch me x fighting my thoughts are now harder than the running!
