16 Plank Exercises for a Stronger Core

By , SparkPeople Blogger
The plank, according to many experts, is one of best exercises to help strengthen our core muscles, which are key in supporting the back and abdomen. And because there are many different variations in performing this exercise, they also help strengthen our hips and pelvic floor, as well as our shoulders and arms.

A strong core has been known to help provide better stability and better posture, as well as making us better and more efficient walkers and runners. In addition, a strong core helps us to perform everyday activities with a little more ease. The plank has also been shown to help relieve back pain

The best thing about the plank is that it does not require any fancy exercise equipment to perform and can be done almost anywhere, at any time. Remember that form is of the utmost importance so be sure to keep your spine straight throughout, as you do not want your back to be arched, nor do you want it to sag.

Certified personal fitness trainer Cheryl Russo recommends starting small. Once you have mastered the traditional plank, consider moving on to some other variations in the beginner section, then see if you can do any advanced moves. 

For all planks, Cheryl suggests starting in a tabletop position on all fours, wrists under shoulders and knees under hips with a neutral spine (the position your spine takes naturally). Then, take a deep inhale and draw the belly button up and back toward the spine without rounding your back, keeping your neutral alignment. In this manner, you are creating a reverse contraction, which is an isometric contraction that reaches the transverse abdominis (deep muscle of the abdomen).

From all fours, move to a modified plank, then from there into whichever plank move you choose from the list below. Cheryl has her clients perform the reverse contraction while in the plank position, cueing them to push the rib cage down toward the ankles and to pretend the torso is a sponge and to ring out all of the water. Hold here for 10 seconds, then lower the knees to the ground for five seconds and then go back into the plank and hold for 10 seconds, then rest again for five seconds. Do this for a total of 60 seconds, taking out resting periods as you grow stronger. 

If you have a history of back pain or spinal issues, check with your physician to receive medical clearance before trying any of these exercises. Once you're ready, clear out some space, grab a mat, get your stability ball and get planking. 

Beginner Moves

The Traditional Plank 

How to: Draw the belly button toward the spine to protect your lower back. Arms are straight with the wrists under the shoulders and fingers of the hands are spread like a fan, pushing into the floor. Retract the shoulders, keep the body straight, pushing the ribs toward the ankles to engage the core. Look six inches forward on the floor to keep your head in line with the spine. Don’t let the hips rise up like a camel or drop down like a cobra.  

Modified Plank

How to: 
Follow the same description as the traditional plank, except you should place your forearms on the floor parallel to each other, forming the number 11, with your elbows under shoulders.

Up-Down Plank 

How to: Start in a modified plank position. Press your right hand into the mat as you straighten right arm and begin to rise. Then, straighten the left arm to bring the body into full plank. Bend the right arm and place forearm on the floor. Bend left arm and place forearm on the floor into modified plank. Repeat, starting with the left arm. Do five to 20 reps on each side, depending on your fitness level.

Side Plank

How to: One arm is straight with the hand in line with the shoulder, fingers spread like a fan. Hips are stacked in line with one leg on top of the other. The belly button is drawn towards the spine to stabilize the core muscles. If you need more stability, stagger the feet. Switch sides after completing your plank on the right side. Hold the plank for 10 to 30 seconds on each side, depending on your fitness level. (In side plank, the challenge happens by adding on levels, not necessarily time. You can raise the top leg, raise the arm, drop the hip down and up, add a dumbbell, etc.)

Modified Side Plank

How to: Same as side plank, except your forearm is on the floor, perpendicular to the torso, elbow in line directly under the shoulder. Switch sides after completing the plank on one side. Hold the plank for 10 to 30 seconds on each side.

Side Plank With a Stability Ball

How to: 
With the stability ball at your side, place your forearm on the ball, keeping your belly button pulled into to the spine and lifting up out of the forearm. Legs can be straight and stacked for an extra balance challenge. Switch sides after completing the plank on one side. Hold the plank for 10 to 30 seconds on each side.

Modified Side Plank With a Stability Ball

How to: Kneeling, with the stability ball at your side about four inches away, extend your top leg out to the side and straighten, keeping the bottom leg bent. Lean your side body over the ball, keeping the hips stacked and the belly button to the spine. Lift up from the top of the rib cage and extend the top arm toward the sky. Complete your allotted time, then switch to the other side. Hold the plank for 10 to 30 seconds on each side.

Reverse Plank

How to: 
Sitting down with legs together and straight out on the floor, place your hands on the floor behind you in line with the shoulders with your fingers facing forward toward your heels. Press the palms into the floor while raising the hips up forming a straight line from the shoulder to the hips to the ankles. 

Advanced Moves

Star Side Plank

How to: 
Start in a side plank with straight arm and palm in line under the shoulder.
When your hips are in line, your top arm reaches up to the sky. Then, raise your top leg up, flexing the foot. 

Side Plank Flip

How to: 
Start in full plank and rotate the torso, shifting the weight into one arm and one leg to turn into a side plank. Thread or bring your left leg under and through the torso on a diagonal, landing the leg on the floor, while rotating the right side of the torso up toward the sky and lifting the right arm straight into the air over the shoulder, straight toward the ceiling. Rotate back to center in a full plank. Rotate to the other side to repeat the same movements and then rotate back to full plank.

Forearm Plank on Stability Ball

How to: 
With legs slightly wider than hip distance and straight, place forearms on the stability ball keeping the elbows in line under the shoulders and trying to keep a 90-degree bend with the arms. Press the forearms into the ball, without collapsing into the shoulders. To make this more challenging, really press the forearms into the ball, while you move your arms forward and back, or in circles like you are stirring a pot.  

Leg Plank on Stability Ball

How to:
 Place both legs on top of the stability ball either close to the knees, the shins, the ankles or the toes. The less of your body on the ball, the more challenging the pose, and the more the abdominal muscles have to work to stabilize the core. Move into a full plank position with the arms straight, wrists directly under shoulders, eyes in line with the spine and your belly button pulled in.

Bird Dog Plank

How to: 
Start in full plank position. Extend your right arm forward, keeping it at shoulder height parallel to the floor. Extend your left leg backward, keeping it aligned with the hip and parallel to the floor. Slowly lower arm and leg back down, then repeat on the other side with the left arm and right leg. 

Plank Jacks

How to: 
Starting in a full plank position, keep the belly button pulled to the spine. Inhale and on the exhale push off the ground with the balls of the feet, jumping with straight legs to extend them out wide, like the base of a triangle or pyramid. Take another deep breath in and on the exhale, push through the balls of the feet and jump your legs back to the starting position. Do five to 20 reps on each side, depending on your fitness level.

Alternating Toe Touchdown

How to: 
Start in full plank position. Shift the weight back and up, raising the hips to form a triangle or pyramid as you reach your right arm back to touch the shin or toe of the left foot. You can also touch the leg on the same side of the arm, or the opposite if that's easier. Come back to full plank and repeat with the left arm reaching back. Do 10 to 15 reps on each side.  


How to: 
Start in full plank position. Raise the right leg up. Bend the knee, flex the foot and open the hips, trying to stack them. Bring the leg back around, gently touching the knee to the floor. Go back to full plank and repeat with the other leg. Do five to 20 reps on each side, depending on your fitness level.

Last Year, I started training for the Marine Corps Marathon. I took on a Coach to help me safely train. It was basically resetting my training as I was slacking due to a lot of relay races and triathlons. I learned how to train daily and realized the importance of a strong core. These exercises were not easy BUT I gained balance, strength, and less run injury prone! It didn't affect my spinal nerve damage either! Thanks for a great blog, Coach Nancy! I'm saving it! Report

I tried several of these as I read through article and found them challenging. Probably if I spent a few minutes/day of various planks, I would become stronger and more balanced. The trick would be to stay on one of them long enough to actually strengthen my core rather than the muscles of my arms or legs. Report

Love to plank, Iíve tried many of these...canít wait to do the others. Serious CORE work, an honest to goodness game changer. Select a form that you feel comfortable with, build slowly from there...focus on form. You just might amaze yourself. Report

LOVE planks of every kind (except reverse ones--haven't gotten the hang of those yet--but i will....) Report
My favorite plank exercise isn't listed. You put your feet on a foam roller, forearms on the ground, and hold it. It is HARD, but it is likely responsible for 85% of the muscle definition I have in my abs now. Report

Where are the exercises? All I saw were pictures of the author posing in skimpy clothes. Waste of time. Report
like others said not all the links work. i will try the reverse with leg lift very interesting Report
yeah, the old links are now dead - it would be great if you could update this list of plank exercises with Spark links. Report
When I went to look at the traditional plank and a couple of other versions of the plank, all I am getting is an add or a website that does not show the exercise. Don't mind the add or the web site, but I what I wanted never showed up. Please fix the links to take us where we are suppose to go. Report
The link I tried (up-down plank) doesn't work correctly--it goes Shape Magazine "Healthy Holiday Boozing Tipsófrom Your Bartender" Report
Are my arms and legs supposed to shake? I'm not sure I'm doing it correctly. Report
Just an FYI--there were a few links that were dead under this article as of 10/26/13: The up-down plank, the star-side plank, the side plank with stability ball (though the one above--side plank on ball, is ok), and plank with knee touch. Report
The Star Side Plank looks awesome! I probably would NOT try the Side Plank w/ a Stability Ball, though, as I'm somewhat of a clutz and that looks like a major accident waiting to happen.

A note of caution on the Up-Down Plank: make sure your box or step, or whatever you're using, is secure and won't slide around. Report
I don't know about you're neck of the woods, but up here in central Ontario, Canada, "planking" is the new in thing. Kids (including my grandson, age 14) plank on objects like a letter box, statue, handrail, get their photo taken and then paste it on a social network site, like facebook. I kindle this interest and don't tell him it's good exercise! Report
Your arguments for doing the Plank in its various forms are very persuasive - will definitely be giving it a try. Thanks for posting. Report
