Focus on pressing your chest and head down into the water to elevate your hips and legs in a horizontal position to reduce drag in freestyle swimming. Keep your head, hips and heels close to the surface to maintain a streamlined position. When performing a stroke, refrain from crossing over the center line with your arms and ensure that your movements are even and controlled. Additionally, pay attention to your head position, looking down or slightly ahead and do not hunch so much at the hips and knees.
