Today we're going to be looking at a perfect front crawl model, so we'll be focusing on the head, body, arms, and leg positions. So looking at the body position for front crawl, you want to aim to keep the body parallel with the water, as flat as possible so you reduce any water resistance and are more streamlined. The arms encourage the body to rotate lengthways, rolling side to side.
So when swimming front crawl, you want the water to meet hat height, looking slightly forward and not down. It's best to breathe on alternate sides, so every three or five strokes, as breathing on alternate sides encourages good body rotation.
A common mistake with head position is being too low in the water as it creates more resistance. If you ever watch elite swimmers, notice they make this as smooth as possible with little resistance.
The leading arm reaches forward, fingertips first, and should be fully extended before catching the water. You want to keep the elbow slightly higher than the forearm, and as you pull, keep the arm close to the body, down the center line for streamlining.
At the end of the stroke, the elbow should be straight, and the hand connects it when it pushes past the hip and the elbow can be flexed again. Alternate this pull between your left and right arm for a perfect front crawl arm pull.
For a perfect front crawl leg kick, you want to keep the feet and ankles as loose and relaxed as possible. Kick the legs alternately from the hips, with six kicks to one arm pull, as this helps to balance the body. Make sure you don't kick from the knees, which is a common mistake for some swimmers, as it breaks the streamlining and slows you down.
