While the appearance of lean abs is appealing to the eye, the strength and functionality of the core is even more important. A strong core will allow you to perform all the household, leisure or sport activities safely.
Strengthening your core does not mean that you just train your abdominals to get them to look pretty. The "core" means everything in the center of your body, such as the abdominals, obliques, and the lower back.
You can strengthen each muscle group separately, but ultimately, the best and most functional way to strengthen your core is to do exercises that work everything in unison—all your body parts move at the same time.
One of the best exercises to strengthen your core is the plank.

PlankGet down on the ground on your hands and feet. Align your shoulders over the hands and spread your fingers wide, pointing forward. Keep your both arms symmetrical and straight. Your lifestyle creates many imbalances in your body. During your fitness training always be cautious of your posture so you will not add more imbalances.
Maintain your body straight like a plank, with the hips 1 inch above the line linking your feet and shoulders. Engage your abdominals at all times and breathe deeply. Hold this position for one minute and over time increase the interval until you can do two minutes without rest. That is a sign of strong core.
As you get tired, the hips want to sink lower. You have to stop them so you don't put excessive pressure on your lower back. If your body starts shaking, continue breathing and try to relax. Relaxing while your muscles are under tension is not easy, but it is a good practice for life.
If you feel discomfort or pain in your wrists, perform the plank on your elbows instead.More: Art of the Perfect Pilates Plank
