4/6/8-Count Drill
This can be done for both Freestyle and Backstroke. Kick on your side for a count of 4, 6 or 8 kicks (or counts). Take one full arm stroke to rotate to your other side for another 4, 6, or 8 kicks, and continue through the swim. While on your side, focus on correct body position. When executing the switch, begin by lifting the elbow of the arm on the water surface (top arm) and recovering it over the line of your body. The extended arm (bottom arm) stays extended to maintain a streamlined body position, until the elbow of the recovery arm has passed over your head. Then execute a quick switch to your opposite side. Use core body muscles to rotate, while maintaining a hold of the water with your bottom arm.
