What you have to try and do is prove to them you will exercise every day or however often you say you will and encourage them to try it too. The best way to stop people from thinking negative thoughts about you is to stop thinking that they think negative thoughts about you and try to create conditions where them thinking negative thoughts about you is impossible. I admit I have the same problem sometimes. I sometimes do not do what I want to because I fear there will be a backlash from my family, telling me what I do is stupid or irrational, or that I do not have the experience, and I just pass it off into the universe and say, "I'm doing this no matter what."

And if you fail, you fail, but do not let other people's negative reactions influence your life. Do what you feel is right, and if someone tells you you shouldn't or you are crazy, then just pass them off as someone who challenges you, and go about doing whatever it is you want to do. Show them if you set out to do something, you will do it.
