Started lesson on Butterfly.
Kicking, curvy motion with legs bending only a little bit. Stomach push in, the rest follows. Did a few laps of kicking, with breast-stroke breathing.
Hand motion drawing a circle right down to the chest, then pull all the way upwards till thumb touches thigh. Hands straight, move parallel to water surface and land again. Try with kicking, but without breathing.
Breathing: heads up as hands at the back and tuck chin in as hands goes under.
Attempt fly with breathing.
Then alternate practices with fly and front crawl.
