These are the notes that three NEM participants took at a butterfly and breaststroke clinic on December 11, 1995, at Harvard's Blodgett pool. The clinic was organized by NEM Bob Seltzer and conducted by Harvard coach Josh Stern. The "anonymous" source did not want to be accountable for inaccuracies.
Arms: Do not bring arms into the chest. Correct motion is simply a scull. Explode forward with hands. Never turn palms up. More speed comes from increasing your speed. Go quickly into the next stroke.
Legs: (Kickers are born, not made.) Kick with the toes out wide. Set up your feet early.
Streamline: Don't look where you're going. Stretch out when kick explodes. Chest will be lowest point of body. Arch shoulders. Angle of the body keeps feet from breaking the surface. Shoulders are out of the water.
Recovery: Not over the water. Extend towards the wall. Hands ideally near the surface; not up and over. Forward to set up the kick. Knees inward during kick.
Pull: Begin by turning thumbs down for increased reach, chest drop and hip rise. Bring elbows together under chin, palms facing [and think of having cymbals attached to forearms and clapping together]. Extend arms. No pause (Arms only visible at in-scull.)
Kick: Most propulsive part of stroke. Kick throws head and chest forward (not up). Use hamstrings to lift feet to bum (do not drop knees). Turn toes out as feet go up. Explode feet around and together, keeping knees as close together as possible. [Kick lane lines.] Timing: Lift feet as you in-scull. Kick as arms reach extension. Tempo of in-scull and kick stays constant (explosive!). To change pace, increase or decrease length of glide (extension held).
