15. Feels like fun. If you find the kind of exercise that fits your personality and motivational needs, you can actually have a good time while your body does the work. Some people need to exercise in a group class because they enjoy the social opportunities it provides. Others prefer to have time to themselves away from the stress of work and family. Whatever your exercise style, once you get into a routine, you’ll find that the activity itself becomes rewarding. Perhaps it’s those endorphins or the benefits of social support from your gym-mates. Whatever the cause, long-term exercisers love this natural “high” and wouldn’t give it up for anything. Once you get to that point, exercise enriches the quality of life.
