1. Maintain lateral alignment in the front crawl and backstroke by rotating the body around its longitudinal axis in synchronization with the downward and upward movements of the arms.
The entire body must rotate, from head to toes, as an entire unit. Never try to maintain one part—the hips or legs, for example—in a flat position while the arms and shoulders are moving up and down.
2. To reduce form drag, keep the head in line with the trunk whenever possible. The only time the head should be out of alignment is when it is lifted out of the water for a breath in the butterfly and breaststroke. The head should remain aligned with the trunk when it is rotated toward the side to breathe in the front crawl stroke.
3. Maintain horizontal alignment by swimming through the water, not over it. Any efforts to elevate the head and shoulders above the water will only increase form and wave drag. The exceptions are the butterfly and breaststroke, in which swimmers should raise the head and shoulders out of the water to breathe.
Even swimmers in these strokes should maintain a horizontal body position during the propulsive phases of the arm stroke and kick, however, at least when it is possible to do so.
Hope this will help you.
