Core exercises don't require specialized equipment or a gym membership

Any exercise that involves the use of your abdominal and back muscles in coordinated fashion counts as a core exercise. For example, using free weights in a manner that involves maintaining a stable trunk can train and strengthen several of your muscles, including your core muscles.

You may also try several specific core exercises to stabilize and strengthen your core. Some examples of core exercises include planks, situps and fitness ball exercises.

A bridge is another example of a classic core exercise. Lie on your back with your knees bent. Keep your back in a neutral position, not arched and not pressed into the floor. Avoid tilting your hips. Tighten your abdominal muscles. Raise your hips off the floor until your hips are aligned with your knees and shoulders. Hold the position for as long as you can without breaking your form.
