Butterfly Swimming Stroke



Here is a picture of me swimming 200 yd Butterfly for CSUN Division I  NCAA.  Some food for thought for those not familiar with swimming,  colleges all race in 25 yd pools.  One way (one lap) is 25 yds, while  for the rest of the world including the USA year around swim clubs all  swim with 50 Meter pools.  If you ever have the opportunity to swim in a  50Meter pool, you will notice a significance in size.


Butterfly Stroke:

  • Imitates the movement of a Dolphin
  • Use momentum to keep moving/ Timing is crucial
  • 90% of the body is used as the kicking in the stroke
  • Breathing can make or break the stroke
  • Arms have little to do with the stroke, even though it is the only thing you can see above water
  • Perfect example of trial and error to really perfect the stroke


Butterfly Stroke 101:


The butterfly stroke imitates the movements, which a dolphin  performs.  The only exception is that a dolphin does not have long limbs  like we humans do, therefore, this makes it very difficult for the  human to perform the stroke.  Visualize a dolphin swimming; it performs a  worm like motion from the nose all the way to the back of the fins.   Now visualize a human with the arms to the side and perform the same  worm like movements from the nose to the toes.  You can not let the legs  separate because now you will have less surface area to push the water.

Momentum is key to keep the movement going without any  interruptions.  This is when timing plays a huge role in the stroke.   Being able to time the dolphin kick, while incorporating the arms and  breathing makes it a timing stroke.  i.e. when cooking a meal you must  be able to time accordingly to make sure when you are all done all the  dishes are done on time without getting cold or burnt.  If you take a  butterfly stroke then pause and try to take another stroke, momentum  stalls you and you will start sinking like a rock.


When the stroke is broken down we end up with 3 different components:  1st the dolphin kick, which starts from the head and ends at the toes,  2nd the arms gives us additional speed & control, 3rd we have the  head, which provides slight movement for the breathing.  If any of the  three are misplaced throughout the sequence, Butterfly can be tough and a  long journey to perfect.


The head only moves a couple inches throughout the Butterfly Stroke.   It moves slightly up (leading with the chin to prevent excess movement)  to provide air throughout the swimming.  If the head moves too much it  will create drag throughout the swim and if compared to a dolphin there  head does not move too much.


People think that the arms have control over the movement of the  butterfly stroke, the truth lies in the kick (Full Body Kick).  Going  back to the comparison of dolphins and humans, we have limbs which make  it difficult to imitate the motions.  We use our arms to provide more  propulsion through the water and allows control.  If the arm timing is  off by a second, it will slow the momentum causing the stroke to use  power to compensate for momentum.

Swimming is a sport/ activity, which requires lots of time and effort  (time=years of practice).  Since water is completely different then  land, we must indulge our bodies in water to create a second nature  feeling.  i.e. we are born on land and learn how to adapt to land, while  water animals spend the life in the water adapting to their  surroundings.  If you were to have a child start learning and spending a  couple hours in water, after several years the child would adapt to the  water’s surroundings.  Therefore, trial & error plays a crucial  role in developing an experience swimmer.  Another example of trial  & error is having a child just play in a body of water everyday  without any real instruction.  Since water has different rules &  properties then land, the child would adapt by learning what movements  in the water make it easier & efficient. After the basics of  movement in the water are mastered, you introduce specific drills/  training, which emphasize further adaptation for correct movement for  all the different swim strokes.


Further Analysis of the Butterfly Stroke:


Learning and perfecting the Butterfly Stroke is very complicated  especially reading it in text.  This is something that would make more  sense in person and being able to show visuals.  At the bottom of this  post I will show several pictures to see if it helps connect the dots.   Remember that since we are land based mammals, we need to imitate the  masters of the water (In the case of Butterfly the Dolphin is the  closest).  Either through still shot photos or in person, being able to  look at how the dolphin is structurally put together and how it uses its  body to move through the water.


Every time the dolphin picks up speed it presses its head/upper body  down and out in front keeping the same movement.  So humans need to  first learn how to properly use the dolphin kick motion.  Since this  part of the stroke accounts for the most powerful part, the movement  needs to be practiced over and over.  Keep looking down 45 Degrees in  front and keep press both the head/ chest down and out in front.  This  creates the initial start of the dolphin kick and maintains momentum.   As you press the head/ chest, the movement follows through naturally  towards the toes. The most important part to keep the kick moving  smoothly is maintaining the knees together to prevent water from sliding  through and not providing optimal surface area to create more power.


After the kick is mastered, breathing and head position added into  the mix.  Now we have the Dolphin kick with proper head position and  breathing incorporated into it.  Since our goal is to learn to swim  butterfly, we would have to imitate and set up for the stroke.  Work on  dolphin kick towards the surface of the water and taking a couple  breathes making the transition smooth & effortless.  While  performing the dolphin kick toward the surface you should feel your hips  expose towards the air and come back down into the water.  This will  encourage consistent momentum and efficiency.  Excess bending of  the  knees and head will hinder the  movement and cause choppy movements.   Remember: the masters of the water are graceful and all movements are  soft.

Once the dolphin kick with head position are mastered, the final  piece of the puzzle are the arms.  Again, since butterfly is very  complicated and depends on timing, we want to start off by swimming with  one arm.  Using one arm allows you to get a feel for what the arms  should be doing and is a lot easier then starting with two arms.   Remember that you want to stick to the main goal of swimming butterfly,  butterfly is not swam on its side or rotating.  Swimming butterfly with  one arm makes it tempting to rotate like the front crawl/freestyle.   This is when swimming flat (shoulders & Hips Square to the bottom of  the pool) is crucial.  There are two options with the arms; 1st the non  moving arm should be to the side of the body, 2nd the non moving arm  should be in a stream line position (elbow touching the ear with fingers  straight out in front).  When pulling with the arm keep in mind that  there are no straight lines in any style of swimming.  Elbow should be  slightly bent and pulling straight under the body.  Once you pull down  towards your hips, your thumb should tap the hips confirming a wide  range of motion.  The next question is when should I pull and kick?   When when the arm is out in front, the kick should start.  As the kick  starts, the arm slightly bends and starts to pull.  An easy way to know  if the timing is correct is to make sure that as your thumb hits your  hips, your hips should be in the downward position of the kick.


Now we finalize the Butterfly Stroke by practicing it with both  arms.  As both arms are out in front, the head/ chest should initiate  the kick by pressing down/ outward, while keeping the arms out in  front.  After the the initial kick starts, you slightly bend the elbows  outward and start pull underneath the body creating a diamond shape.  As  the thumbs hit the side of the hips, the kick should be traveling down  towards the hips and off into the toes.  The key components to the kick  from the hips down are to keep the knees together and the big toes  together.  The ankles will flare outward giving it a fin like shape to  provide optimum surface area.


If you have questions, ASK!  this stroke depends on a lot of coaching  and visualization. Any slight confusion, will result in frustration and  lack of progression.
