For many people finding motivation to get into a regular exercise routine is simple. They may be looking to lose weight, build muscle or simply tone up.

But what about those of us who aren't motivated to change our bodies, or don't see significant physical change as a result of regular exercise? How much motivation is there for us to maintain our workout routine? The answer is plenty.

While the health benefits of regular exercise are well documented, here are three other reasons to keep up with your workouts.

1) Improve your mood

Stressed out at the office? Burned out on bills? Feeling overwhelmed with life in general? A brisk 30-minute workout may be exactly what you need.

Exercise stimulates various brain chemicals, which may leave you feeling happier and more relaxed than you were before you worked out. Not to mention that completing a good workout brings a sense of accomplishment, which can boost your confidence and improve your self-esteem. Exercise even reduces feelings of depression and anxiety.

2) Get better sleep

A good night's sleep can improve your concentration, productivity and mood. And a great way to help you fall asleep faster and deepen your sleep is regular exercise. The timing is up to you, but if you find that you're having trouble sleeping at night you may want to try a late afternoon or early evening workout.

3) Stay in touch with friends and family

Let's face it. Staying in touch with friends and family isn't always a top priority. If you're juggling a family and a job, it can be difficult to make time to stay in touch with the people who matter most to you.

By setting up a regular workout schedule you have an excuse to catch up without any outside distractions. Best of all, having an exercise buddy is a great way to stay motivated to keep up with your workouts.

Regardless of whether or not you're trying to shape your body, there are plenty of reasons to keep up with your workouts. Find your motivation and get started today.
