One of Kelsi’s favorite ways to improve her butterfly is to do dolphin kick on her back, with fins, and with her arms in Position 11.   She thinks about starting the kick at the chest and letting it flow through the body, legs, and down to the feet.  The fins amplify the whip-like motion of the body.  Kelsi tries not to kick from the knees.  Instead, she drives everything from the chest and torso.

Kelsi’s precision and control can be seen in the fins, which leave just the barest trace at the surface of the water – every…single…time.
