Fins stayed on for entire swim
Push off to 3 or 4 dolphin kicks, transition to flutter kick (without pause) taking only one powerful stroke while holding a solid flutter kick with leading arm stuck to ear in streamline (for about 6 flutter kicks), complete cycle by taking next stroke and hold again (example: breakout drill with 2 fr strokes).
This drill reinforces stremline at breakout, I found a common mistake is opening up at breakout and know I am guilty of this.
