回答: That flutter kick can not be too slow otherwise you sink 由 HunHunSheng 于 2006-5-30, 08:12:25:
 I am not a master of freestyle, I did breaststroke
 and butterfly better. However, if I go slowly,
 I can do freestyle continuously for a while. Problem is,
 I find it extremely boring swimming non-stop for
 > 20 minutes. If you jog, you can at least look at
 YN or listen to music. Underwater, even the vision of
 half-naked YN is blur...
 You may want to perfect your stroke and kick so it 
 will be in sync to save energy. You will want to
 twist your body to breath, that is important to prevent
 sinking...
