The plank is one of the simplest exercises that you can do – it’s simple
 in its appearance and the amount of steps involved in doing one. Being 
simple, though, does not mean that doing a plank is easy.
Getting into plank pose can be easy. Holding a plank can even be easy, 
for a few seconds, but since the plank is an exercise position that can 
be held indefinitely, its difficulty can range from easy, short-term 
planks to excruciating tests of endurance. A heads up: easy, short-term 
planks aren’t the type that are going to provide you with much strength 
improvement.
Planks are one of the best core exercises
It’s
 debatable as to whether or not an exercise regime consisting solely of 
planks would give you a six-pack by itself. The odds are pretty slim, 
and the amount of planking you would have to do would be absolutely 
ridiculous, but including a plank as part of a varied routine shows some
 immense benefits.
Planks go best when mixed with an assortment of cardio and strength training exercises, and they show this by improving the benefits that you reap from each individual exercise and type of training you do.
Some of the most important groups of muscles that are targeted by the plank are:
- The transversus abdominis,
 which is a set of core muscles that ultimately lays the foundation that
 enables you to develop your abs. The transversus abdominus must first 
be trained for you to build and develop your rectus abdominis, which is 
the front area that most people shooting for a six-pack are observing 
when they’re looking in the mirror.
 - The rectus abdominus helps greatly improve sports performance and your ability to jump high.
 - Your
 oblique muscles are responsible for your ability to bend sideways and 
twist your waist, and are often underlooked during exercise routines
 - Your glutes are what help support your back and help to provide the often-desired shape of your backside.
 
Your
 core is crucial for helping keep your spine in alignment, as well as 
maintaining strength in the rest of your back. Core strength helps keep 
you safe from strain injuries.
The core must be trained on a 
regular basis, and a lot of people don’t know this. Doing too many 
exercises that target specific muscle groups – weight training, for 
example – neglects the core and can lead to disproportionate strength 
and injuries later in life. Planks are a great way to maintain strength 
in the core.
2. Planks will improve your posture
Planks are able to improve your posture , which is incredibly important for a number of things.
- Good
 posture prevents your body from developing injuries by improper weight 
distribution, which can affect everything from major exercise routines 
to small movements like bending over.
 - Proper posture displays 
confidence and self-assurance, which can be very attractive for people 
hoping to appeal to the opposite (or same) gender
 
Since 
planks work your core, that means they work basically the whole body, 
from your pelvic girdle to your shoulder girdle as well as your legs.
The
 plank strengthens your spine, your rhomboids and trapezius, and your 
abdominal muscles, which naturally result in a strong posture as they 
grow in strength.
Developing your posture can improve on a number of ailments, and prevent the onset of other ones.
- Good
 posture means you’re keeping your bones aligned. This means that you’ll
 lower the risk of skeletal injuries, you’ll be able to lift more, and 
your body will put less strain on your joints and bones to prevent the 
development of diseases like arthritis.
 - Improving your posture 
means that you’ll position your internal organs better, which can 
nullify any digestive issues or other functional problems that may have 
been caused by your internal organs being forced out of their natural 
position by bad posture.
 - Good posture increases your height, 
making you appear lean and actually increasing your height a bit; these 
bonuses come without an increase to weight (though this may naturally 
come as you continue working out.)
 
3. Planks help get rid of back pain
This
 benefit is partially due to the improved posture that planks provide, 
but the significance of the plank’s ability to affect back pain deserves
 a section of its own. The plank doesn’t just inhibit certain types of 
back pain but enhances the health of the back as a whole.
The improved posture alone helps to align the vertebrae,
 which takes off unnecessary stress in the spinal region. This also 
helps to arrange the ligaments in the back properly, which further 
prevents painful back conditions.
Planks help you build up the 
muscles in your abdomen, which allows further support of your posture. 
Having strong abdominal muscles also means that your body feels less of 
your weight – remember, you’re holding up hundreds) of pounds every 
second you’re standing, and all this strain comes back on your bones, 
joints, and muscles. Strong abdominals take a lot of this stress off 
your back (this is part of the reason that waist-straps are so helpful 
when carrying heavy backpacks!)
Having strong abs and sitting or standing up straight prevents several unpleasant things from happening.
- Osteoarthritis, a degenerative condition related to the joints in your body, is less likely to develop with proper posture
 - As
 you age, your body naturally loses some of its mobility. Having proper 
posture and strong core muscles helps to prevent this from happening too
 quickly.
 - Neck and shoulder pain can also be caused by improper 
posture or by straining the muscles in your core, so keeping them strong
 is a key way to avoid unwanted injuries of these areas.
 
4. You’ll become better coordinated
One
 of the best benefits of planking doesn’t come from actual muscle 
growth, but from its ability to help you train your muscles to be more 
stable.
The body uses its core muscles to help maintain balance.
 This is obvious when you’re running, biking, exercising in any way – or
 during active leisure activities like dancing. Many people think that 
their extremities are responsible for their balance, and they are, in 
part – but the majority of your stabilization comes from your core.
Having
 a strong core helps you avoid injuries that could be caused to single 
muscle groups that might be over exerted by trying to maintain balance 
during aggressive exercise. For example, snowboarding relies heavily on 
the calves for balance, and having a strong core can reduce some of this
 strain.
Strengthening your core also teaches you how your body 
and muscles work together, and can help improve your ability to work as a
 single unit instead of trying to control a bunch of different muscle 
groups simultaneously.
Planks also help build endurance of these 
muscle groups, so you’re able to maintain balance in physically 
exhausting situations for longer times.
Performing endurance feats
 like planking also carry with them a very trying mental aspect. Many 
people say that half of a workout is in your mind, and the plank is 
great proof of this – many people can hold a plank for much 
longer than they believe that they can, but they give up too soon. Doing
 regular plank training, and continuing to motivate yourself to hold a 
full plank, can have incredible benefits for your focus and concentration.
If
 you’re able to hold focus during an intense exercise like a plank, 
imagine how easy it will be for you to focus on other tasks
5. Planks improve your flexibility
Unlike
 some exercises that simply improve the strength of your muscles, planks
 offer a versatile range of benefits – not the least of which is improving your flexibility.
Planks
 make your posterior muscle groups – not just your glutes, but all of 
the muscle groups in the back of your body -much more flexible. These 
include the muscles around your shoulders and your collarbone area, and 
your shoulder blades themselves. These muscle areas will grow and 
stretch with continued planking, which is great because these areas are 
often neglected during many traditional exercise routines.
The plank is an important pose in many yoga routines.
 Yoga is a great form of exercise for people hoping to build core 
strength and improve flexibility, the the plank being considered a core 
element of many yoga training routines indicates just how beneficial it 
can be not just for your core, but for your flexibility as well.
Side planks, a variation we will discuss later, allow you to stretch out your sides, improving flexibility from the hip area.
A tip for enhancing the flexibility bonus you’ll gain from planking is to do a rocking plank,
 again, discussed in detail later. Once you’re in the plank pose, rock 
your body back and forth by moving your toes a little bit in either 
direction.
6. Planking will improve your metabolism
Planking burns more calories, when done every day, than other core exercises like situps.
More
 importantly, planks help strengthen massive muscle groups in your body.
 Having strong muscles means you burn more calories, even when you’re at
 rest.
This makes planks crucial for people who work in offices or
 other jobs that aren’t very active. If you have good, strong muscles on
 your body, you will be able to burn calories more effectively and be 
less at risk for gaining extra weight.
On top of that, having strong muscles means you burn even more calories when you’re exercising,
 even if this exercise is simply walking to work or school in the 
mornings. It also means that you’ll burn more calories in your sleep!
The
 other side of this benefit is that, since you’ll be burning more 
calories, you’ll feel hungry a lot more often. This can be a great 
opportunity for you to begin eating a healthy diet – since you’ll be 
hungry for more calories, you can eat more, and if you’re deciding to 
eat nothing but healthy food, you’ll begin to reap the benefits of a healthy diet in no time.
A lot of folk consider being hungry all the time to be a terrible affliction because it means that they’ll gain weight. This can
 be true, but it only becomes a problem if the individual has a bad 
diet. Eating lots of food can be great for you, and if you’re exercising
 and eating a good diet, you’ll become much healthier.
7. Your mood will improve
What? Planks can even have benefits on your state of mind?
Absolutely.
 A lot of the groups that planks target are groups of muscles that are 
frequently strained and knotted, and contribute massively to stress in 
the human body. Knowing that your body’s physically stressed can be 
draining to your mental state.
Tension in certain parts of your 
body, like your legs, can lead to more tension in other parts of your 
body due to your natural need to compensate – if your legs are tense, 
you will try to put less weight on them, which could strain your back.
