Mix It Up
If you always do the same workout at the same place and the same intensity it will inevitably become monotonous and less effective. One easy change is to add interval training-- short bursts of speed, followed by a longer period of recovery. You might also try a different version of your routine. If you walk, go for a hike or simply drive to a new location for your walk. If you go to the gym, exercise outside for a change. Another option is to try a different type of workout. Take a Zumba class, sign up for martial arts, enroll in an adult swim class or try a new sport or activity you've always had an interest in.
