And the benefits of a strong core extend far beyond just looking lean; working those muscles helps with alleviating pressure (and pain) in your lower back, improving posture, and preventing injuries.

Here's how to do it:

• Start in a plank position with your hands directly under your shoulders and your feet in line with your hips. Cheat your right leg toward your center line, and lift your left leg off the ground so your heel is even with your pelvis.
• Keeping your torso steady, reach your right arm forward. Really brace through your abs by pulling your navel to your spine. Hold this position for 10 seconds.
• Keeping your torso stable, bring your right elbow to your left knee under your body. Do not round your back or twist your spine, and keep your pelvis down. Then reach the arms and leg out and away from each other. This is one rep.
