Duck Swimming
The swimmer lies on the back, arms alongside the body, elbows lightly touching the torso above the hips, with a gentle flutter kick. Propulsion comes from the forearms: they angle alternately outward to about 20 cm depth, palms facing backward, pushing the water away behind the body while the elbows stay close. This isolates the power phase of the advanced backstroke arm stroke — watch the second half of the underwater phase in the core-exercise video.
