If you want to change your habits you may want to change your thinking first!
Think: I hate sports and it works. You keep on hating sports. 
Think: I love to experience something new. Go for a walk and observe what happens inside like a new perspective. Some may observe nervousness or resistance at the beginning and flow of easiness after some time. Make it a game like watching a new TV series. By observing your thoughts can soon choose what you want to keep in stock and what new seeds you want to plant to grow in your perception.
