hI, start small by just opening the door and getting outside, walk to the gate, through there and onto the footpath, if you have music put your earphones on. and walk around your block
get back to the front gate and ask yourself "did that feel ok" and go around again. or, finish there and do the same tomorrow.
You have the right to be fit and healthy and only you can do it. You've heard all this before but I have a theory. I believe our brains - not our bodies are the ones at fault. Our brains like to be the boss and to say "just relax and watch TV and while you're at it have a snack", then the brain settles down to inactivity and just has to press the 'eat more' button - basically our brains would be lazy if we let them.
So alternatively I think we must retrain these brains, trick them, over-ride their ideas, take no prisoners when they suggest overeating or couch potato behaviour. Funny thing once you take your brain for a walk, it really enjoys it and lets you know that quite quickly but is a really slow learner so you have to be persistent and keep the routines going until at a point and ,this is just my thought for now, our brains actually think its THEIR idea to be fit and healthy and then I think, and again I am also waiting for this to happen. then I think we are on the home straight as far as changed behaviour is concerned.
over and out, and keep trying you will succeed.
