I would like to ask how to start cardio training. I for sure searched on google a lot, but still i would much more to prefer some advices from real people.
I am 40 years old, 250lbs. My weight went rapidly up after started my thyroid problems. Now i am on medication and need lost weight. I must still say that i suffer with anxiety that makes me to be in daily in fear from heart attack. (my heart was checked many times and always is ok). I would like to start with a training that would be good for heart and i read the cardio training is good for the anxiety too. But i do not know how to start. I am in very bad shape. Did not exercise few years and my work is mainly on pc so most of my day i sit with computer. I breath heavy and my heart is beating fast just when i go few stairs up or to short way to hill. My muscles are weak.
So my question is... how to start when im in so bad shape.. what i could do alone as is not easy for me to go to a gym... and how to do it dont make some harm instead a good. And what heart rate i should have when doing the cardio training that is save for me.
Thank you very much for advice
