THE PLANK!! I can probably guess many of you have heard of this fabulous core exercise! If you have got away from it? Bring it back to your exercise program.

This exercise strengthen and stabilize your spine and abs and the COOL part is you can do it anywhere!
The abs, low back and hip girdle make up your core. The plank is the basic move that helps you stabilize and build endurance in these muscles. If you do it incorrectly, however, you won't reap any of the move's benefits or be able to advance to other exercise you can add to this. Here is how you do it right!
Start-Get on all fours on the floor with elbows directly under your shoulders. Extend your legs and flex your ankles so your toes touch the floor and your heels push straight back. Keep your abs pulled in tight, leg muscles contracted and back flat. Support your body weight on your forearms, elbows and toes. Your body should create a straight line from your shoulders to your heels.
Movement: Maintain your balance. Hold for 30 sec. Lower your hips to the floor to rest, then repeat for another 30 sec. Do 2-3 sets.

When: do the plank as finishing move after your traditional ab workout or as a warm-up to other plank-based exercises.

With: any abort lower- back-exercises
How: Use bodyweight, or have a partner place a weight plate on your back for more resistance.
