6-kick switch explained: side position, six kicks, then one arm stroke to switch sides. The drill for rotation and balance in freestyle, step by step.
In the 6-kick switch you lie in side position, kick six times and switch to the other side with one arm stroke. The honest answer to "Isn't that just a game?": it is the drill that brings rotation, balance and arm change together in one exercise. It links the side position (the previous skill) with the real freestyle stroke.
The Swim Wales framework lists it as "Single Arm Kick & Switch 12/6": first 12 kicks on the side, then the switch, and once that works, only 6 kicks [1]. The 6 is no coincidence: in a study of seven national and international level swimmers, they maintained a six-beat kick during a simulated 200 m race [2]. The Swiss teaching material also has at most six kicks per arm cycle [3]. When you master the drill, you practise the rhythm good freestyle swimmers know.
Be realistic: the 12-kick version is often learned in one to two sessions. The 6-kick version with a clean switch usually takes several weeks (experience, not a study value).
One arm is stretched in front, the other lies at your body. The body is long from fingertips to toes, you rotate from hip and shoulder to about 45 degrees, head and body stay calm [1]. Pressing the fingertips downward promotes a strong catch position [1]. Milestone: 12 kicks without tipping onto your front.
After the twelfth kick you bring the rear arm forward: the hand first slides past the hip, the elbow points to the ceiling. Then the shoulder rotates forward, the hand sweeps past the head and enters [1]. Entry follows the order fingertips, wrist, elbow, extension [1]. Milestone: the hand enters in front of the head without slapping the water.
The head stays in line with the spine and turns with the body. Swimmers roll further when breathing anyway: in a study at 200 m pace, swimmers rolled 66 degrees while breathing and 57 degrees without [4]. For you this means: you do not have to throw your head sideways in a hurry, you turn with the body. Milestone: you can take one calm breath during the switch.
Only when the 12-kick switch is stable do you reduce to 6 kicks between switches [1]. The kick is now the metronome: kicks 1 to 5 hold the position, the arm change begins in the 6th kick. Milestone: 4 × 25 m with six kicks, the side switches are even.
Practise that the switches run the same left and right. In most swimmers one side is stronger. A study on 100 m freestyle found that most swimmers were coordinated asymmetrically, often linked with their preferred breathing side [5]. Milestone: you feel no difference between left and right at the switch.
Swim 25 m 6-kick switch, then 25 m normal freestyle with a six-beat kick and watch the rotation. The arm change is now your freestyle stroke in slow motion.
Start the switch at kick 5, not at kick 6. Then the hand is already on its way at the 6th kick, and you have no dead spot in the rhythm. Saying "five, six, switch" aloud often gets you into flow immediately.
A drill: six kicks in side position, then one arm stroke to switch to the other side. It comes from a drill series that starts with 12 kicks and is later shortened to 6 [1].
Because good freestyle swimmers use a six-beat kick, so six kicks per arm cycle [2][3]. The drill practises this rhythm slowly.
At the start yes: fins and snorkel help with position and breathing according to the drill plan [1]. Later you leave them off so the balance comes from yourself.
Sets of 4 × 25 m in the warm-up are enough. Afterwards 25 m of normal freestyle so the feel transfers (practice recommendation).
