Want more-defined abdominal muscles? Core exercises are important.

Although it takes aerobic activity to burn abdominal fat, core exercises can strengthen and tone the underlying muscles.

1. Strong core muscles make it easier to do many activities, such as swing a golf club, get a glass from the top shelf and bend down to tie your shoes.
2. Strong core muscles are also important for athletes, such as runners, as weak core muscles can lead to more fatigue, less endurance and injuries.
3. Weak core muscles can also leave you susceptible to poor posture, lower back pain and muscle injuries.
4. Strengthening core muscles may also help improve back pain.

Aerobic exercise and muscular fitness are the primary elements of most fitness programs.

But to have a well-rounded fitness program, consider including core exercises in the mix as well.

Whether you're a novice taking the first steps toward fitness or a committed fitness fanatic hoping to optimize your results, a well-rounded fitness program is the best way to reach your fitness goals.
