This butterfly technique article explains how to properly execute the arm stroke movements. Those movements are somewhat similar to the ones used in freestyle. The biggest difference however is that both arms move synchronously.
We can clearly see the butterfly arm stroke movements in the following video, starring Michael Phelps.
As you can see above, both arms move synchronously. Under water, the hands move from an overhead position towards the hips. The hands leave the water once they are close to the hips. The arms then recover forward above water back to their initial position.
The butterfly arm stroke can be divided in the following phases:
We will now analyze the different phases of this butterfly technique in more detail.
Your arms enter the water at the end of the recovery in front of your head. Your arms are either completely straight or slightly flexed at the elbows. During the entry your arms should be about shoulder width apart or slightly less. Your palms are facing downwards and maybe also a little bit outwards.
After the entry in the water your arms will extend and stretch forward for a short amount of time because your chest is driven downwards and forward by the body undulation.
During the outsweep your arms transition form the extended forward position into a position where your palms and the bottom of your forearms are facing backwards.
To do so, after extending your arms forward, your hands move outwards, downwards and backwards, with your palms successively facing those directions.
Your arms bend at the elbows and remain bent for the rest of the under water arm sweep. Also, during the outsweep, your elbows should remain high, close to the water surface. This insures that you will rather push water backwards than downwards at the start of the insweep.
The catch occurs when your palms and forearms are in line and facing backwards and a little bit downwards. This is the beginning of the propulsive phase of the arm stroke. Your hands should be about shoulder width apart and your elbows bent.
During the insweep your hands move inwards, backwards and upwards, from outside the shoulders to below your chest. This is the first propulsive phase of the arm stroke. The palms are successively facing backwards, inwards and then upwards. The elbows, still being bent, are being brought against the rib cage.
During the upsweep your hands move from below your chest towards your hips. To do so, your palms rotate from facing backwards, inwards and upwards to facing backwards, outwards and upwards. Your elbows are still bent and move a little bit away from the rib cage.
This is the second propulsive phase of the arm stroke and it stops before your arms are completely extended. Otherwise, with extended arms, you will be pushing water upwards instead of backwards.
The release occurs at the highest point of the body undulation when the shoulders clear the water. Your arms should leave the water before they are completely extended and before your hands reach the hips.
Your arms leave the water in this order: shoulders, elbows, forearms and hands with the pinkie first, palms facing inwards. This ensures that you create the least amount of drag while moving your arms out of the water.
You should use the momentum of the release to begin the recovery of your arms. Your arms recover forward in a half-circular fashion and hover above the water surface. The palms are first facing upwards and then progressively rotate until they are facing downwards at the end of the recovery.
At the beginning of the recovery the elbows are always bent. At the end of the recovery your elbows can either be straight or slightly bent. The cycle can then start again.
