So, I am a so-so butterflyer--go 27.5 in the 50 yds and 1:04 IN THE 100 (59 yds old). I can only maintain body position and foreward motion if I am going around :32 on the 50's. I can't maintain any form and swim slower. Anything slower than this and I take on a cork like profile--all bobbing. I would like to learn to swim the 200 but there is no way in this life that I can maintain a :32 sec split--I want to know how I should train/what I should do to smooth out my form, swim slower and be able to hit ~ :36 sec's on the 50's. A mid 2::20's on the 200 would suit me fine.
