Butterfly is a fantastic stroke. When youíre swimming it well and feeling fresh thereís nothing to beat it.
Butterfly may well feel great when youíre fresh but this
feeling is very short lived unless you are very fit and your body is well
conditioned to it.
This is because both a powerful leg kick, which really works the large
muscles in the quads, and a powerful dual action arm pull are used to
propel the upper body out of the water in order that the arms can be
brought over, ready to take the next stroke.
Although itís a fast stroke it is highly costly in
energy and as a consequence the world record times for fly will never be as
fast as those for the more efficient front crawl.
So even when youíve mastered the butterfly stroke donít worry if you can only
manage reps of 25 or 50 m in distance. To achieve much more takes a lot of
We were once taught a useful series of drills that
gradually build up the stroke which we will try to relay here. They have
the added bonus of ending up with two kicks to one pull which is the
correct way to do it. Do a couple of lengths of each step and then move on.
