Exercise.
It's just a fancy way to say: get moving. Exercise drastically increases the ability for your wellness goals to happen. However, exercise doesn't have to be a tedious chore you dread. Find creative ways to get moving that are enjoyable to you. It can be as simple as taking a walk around the neighborhood with your spouse or family or grabbing a tennis racquet and hitting the courts. Enjoy basketball? Play HORSE against your daughter on the driveway. If gardening is your thing then plant some bulbs or pull some weeds (and it would be great if you could stop by my place when you're done with yours). Sign up for tango classes through your park district with your husband.
Exercise doesn't have to mean going to the gym. Find ways to include more movement in your everyday life and reap the rewards.
