These breaststroke swimming drill shows you how to practice the arm stroke on dry land. Learning the technique on dry land first is easier because you can solely concentrate on what the arms have to do and avoid struggle.
Here's a video that demontrates how to practice the arm stroke:
To practice breaststroke swimming's arm stroke, follow the instructions hereunder:
The initial position corresponds to the glide phase of the breaststroke. During this phase, arms and legs are fully extended. Do the following:
The outsweep starts the arm stroke. During the outsweep, the arms and hands are positioned perpendicular to the body. So do the following:
The insweep is the arm's power phase. It's during that time that the arms provide propulsion in the breaststroke swimming's cycle. So do the following:
During the recovery, the arms move back to their initial position:
Once you have memorized the motions of the arm stroke, the breaststroke's breathing technique can be integrated. Basically, what you need to do is to breathe in at the end of the insweep, then exhale continuously for the rest of the arm stroke.
In fact, in breaststroke swimming, the upper body naturally rises out of the water during the insweep, allowing for a quick inhale. Then the upper body sinks down below the water surface during the arm's recovery in an extended position. That is the moment to start exhaling.
To sum up, practice the arm stroke on dry land as described above, and integrate breathing like this: inhale at the end of the insweep, then exhale continuously for the rest of the arm stroke.
Once you have memorized the arm stroke and breathing techniques on dry land, it will be much easier to integrate them with the rest of the breaststroke swimming technique, especially at the pool. So rehearse the arm stroke and breathing techniques at home for a few days until you can execute them automatically.
