It lets you practice balance in the water in the prone position.
You will instinctively know how to prevent your hips and legs from sinking in the water once you have mastered this drill.
Video of this Swimming Drill
The following video shows how to perform this drill:
1) Push yourself off the wall in the prone position. Keep your head in line with your body and your arms at your sides.
2) Start kicking with a relaxed flutter kick.
3) If you notice that your hips and legs are sinking despite the kicking, try the following: push your upper body down in the water to compensate for your sinking legs.
However, your head and upper body should remain in line. Also, do not press your upper body down too much, but only to the point where you return to a horizontal position.
4) You should notice that your body behaves like a seesaw and your hips and legs come back up without effort. This is the main lesson of this exercise.
5) When you need to breathe, look forward an up until your mouth clears the water, and take a quick breath. You will notice that your hips and legs sink.
6) Immediately bring your head back in line with the rest of your body, and push your upper body down as explained above to compensate and get your body back to horizontal.
7) When you push your upper body down in this way to get your hips and legs up in the water, it is sometimes referred to as pressing the buoy or pressing the T.
Here are a few more tips for practicing this swimming drill:
1) If your kick is weak, you can also use swim fins. Just make sure that you compensate for the sinking of your hips and legs not by kicking harder but by pushing your upper body down.
2) Do not overdo this exercise, as lifting your head to inhale can strain your neck. Once you have learned how to push your buoy to keep your hips and legs up, move on to the next exercise.
3) A tip for sinkers from Frank, one of our readers: to bring your hips/legs in balance with your shoulders, consciously engage your lower back muscles and also do dry land exercises to strengthen those lower back muscles.
