You’ll be much more likely to stick with an exercise program if you’re working out with a friend or group.  To start a group ask fellow neighbors if they’d like to walk or workout then set a couple of days to workout for the week.  Once you have a group to workout with you’ll be more motivated because you’ll enjoy the social interaction.  Once the group gets going start challenging each other to workout a little harder.  You’ll love the connection and you’ll love the physical and mental/emotional results from forming a group!
