If your itching to get outside for some exercise there are a few chores your lawn would appreciate. Picking up large debris like sticks and pine cones is a good way to do lots of bending over. Another chore is to lightly rake your lawn. Not only will your be gathering small debris but also allowing the sun to warm the ground and let air get to the plants and soil. Pay attention to any areas that are completely covered by leaves and get them removed.
