Do you believe overweight people should run?
As always I would say do what is the best for you and your situation.
I tried running when I was obese. It was very hard. I didn’t know about walk/run method for beginners. I pushed myself to run for a minute and got tired quickly.
Then I had surgery for a knee and had to wait almost a year to resume running. I also managed to lose significant amount of weight during the non-running period.
When I started again, it was so different; it felt like if I were another person.
I fell in love in running since then and it changed my life.
