How can i maintain, lose weight and keep a specified exercise program during winter?

I don't like gyms and i'm too shy to go in one because people there are fit and muscly than myself. I have lost 20 kgs (46 lbs) over the past 6 months. I need to lose 10 more kgs (22 lbs) to reach my goal weight. But since it is winter where i am i want to be able to exercise, maintain and lost weight without having to use any gym equipment or go to the gym. What can i simply do?
