A good kick rocker should "boil" water, no splash. To achieve this, energized the movement of their legs mainly the muscles of the hip and thigh, not the calf and ankle. Double
knees slightly only in the downward movement and keep your ankles flexible. Must kick just deep enough, about 40 to 45 inches-enough to remain stable in the water more vigorously kick without making you tired much faster progress.
Many swimmers feel more comfortable with a rate of three kicks each stroke.
