My second swimming lesson handout contains step by step instructions and images for the front crawl.
The front crawl, sometimes called freestyle, is the stroke most people think of when they say swimming. Your body is flat and straight, with a rotating movement around the mid-line. Your head position depends on your buoyancy. Most swimmers keep the water line between the eyebrows and hairline; however, someone with little buoyancy may have to lower the head a little to raise the hips to the best level.
