Walking Paths
The perfect outdoor exercise space needs a few good walking paths. If they have rolling hills, so much the better! ┬ęGetty Images/Thinkstock

Walking is one of the best exercises you can do. It costs almost nothing, and has big benefits.

Regular, moderately-paced walks can help you manage your weight, improve your cholesterol levels, lower your blood pressure, and reduce your risk of developing type 2 diabetes (or complications from type 2 diabetes). Walking also helps to lift your mood (it releases pain-killing, mood-boosting endorphins) and keep insomnia at bay [sources: Mayo Clinic, Arthritis Today].

Remember, you're looking for at least a moderate pace while you walk, which means about 100 steps each minute (using a pedometer can help you track your steps). And don't avoid the hills: You'll expend one-third more energy while walking up a 15-degree incline than you will on a flat path [sources: Zerbe, Columbia Health].
