I am 25 years old female. I am having backaches on and off since I gave birth 5 years ago. Used ointments done xray nothing happened. Some doctors says to keep my heart active and take more calciums. Yes I am quite a lazy person. So I started jogging 3 nights before. Noticed that within the first few minutes I get short of breathe and have difficulty in breathing and get tired as if I am going to faint so I stopped every night and did some exercises and came back home. Noticed that happens after I eat even. Now I am having muscle cramps here and there. Can you guide me how to do the jogging a better way for me. Because I get tired way too early. I want to improve it.
