Having a clean swimming technique is essential to develop an effective front crawl/freestyle stroke.
By an effective stroke, we mean being able to swim at a moderate pace in a relaxed fashion or being able to swim fast without getting exhausted too quickly.
With these considerations in mind, we have a few swimming tips below that should help you achieve these goals.
1. Use a Neutral Head Position
Keep your head in line with the rest of your body and look directly toward the bottom of the pool.
While swimming front crawl, many people tend to look forward rather than downward. The problem with this approach is that it can cause your legs and hips to drop.
As a consequence, you need to kick harder to keep your legs up, and you get tired more quickly, and you also get out of breath faster.
Furthermore, looking always forward in this position can strain your neck over the long run.
2. Press Your Buoy
The key to maintaining a good balance in front crawl, so that your body is horizontal and your legs don’t drop, is to learn how to press your buoy.
By pressing your buoy, we mean that you push your chest a bit down in the water all the time.
Let’s imagine that your body is a seesaw. The fulcrum is located between your navel and your groin.
Your upper body is on one side of the seesaw, where your lungs filled with air act like a buoy. Your legs are on the other side of the seesaw.
If you press your chest down a bit, your body will pivot at the fulcrum, and your hips and legs move up toward the water surface.
Learning this swimming technique is often a game-changer, as you can then keep your legs up without effort, and focus on other aspects of your stroke.
I know people that have been triathletes for years and are good at running and cycling, yet have a weakness in swimming because they haven’t mastered this technique.
3. Don’t Lift Your Head to Breathe
Don’t lift your head forward before rolling sideways to breathe. This frequent error also causes your hips and legs to drop.
Roll sideways instead, and at the same time turn your head a bit farther, so that your mouth clears the water.
Doing this should feel as if you were turning your head on a pillow resting on the water surface.
Ideally, you should have one eye cup above the water surface and one eye cup below the water surface. Being able to do this takes time and practice.
4. Swim on Your Sides
When you roll from side to side in this way, rather than swimming too “flat,” you can engage the larger back muscles in addition to the shoulder muscles, and this gives additional power to your arm stroke.
5. Exhale Underwater
To develop an effective front crawl stroke, you need to exhale continuously in the water while your face is submerged.
The rationale for this is that there isn’t enough time to both inhale and exhale sideways during the arm recovery.
Breathing out continuously also allows you to be more relaxed than when you hold your breath.
6. Use a High-Elbow Position
Use a high elbow position while pulling backward with your arm in the water.
The high elbow technique consists in bending your elbow and bringing your forearm in a vertical position as soon as possible during the underwater arm stroke phase.
To keep your forearm vertical, you need to keep the bent elbow as high as possible for as long as possible during the active pull phase.
By keeping your forearm vertical, you increase your grip on the water and, as a consequence, improve propulsion.
7. Don’t Overreach with Your Recovering Arm
While recovering your arm forward, don’t extend it entirely above the water surface before letting it drop at once in the water.
Doing this is a bad idea because it creates turbulence in the water and additional drag.
Furthermore, fully extending the recovering arm above water increases shoulder strain, and can over time lead to swimmer’s shoulder.
It is best to carefully insert your hand in the water half-way at a distance between your head and the span of the fully extended arm, and let the rest of your arm follow into that opening made in the water.
8. Use a Two-Beat Kick for Long-Distance Swimming
A relaxed two-beat kick is ideal when swimming long distances, as it allows you to save energy.
In a similar vein, using the two-beat kick when learning the front crawl allows you to be more relaxed as you consume less oxygen and hence need to breathe less often than when using the six-beat kick.
A two-beat kick means that you kick once per arm stroke for each side of your body, or two kicks over the whole front crawl stroke cycle.
With the six-beat kick, on the other hand, you kick three times with each leg over the whole stroke cycle, or six times in total with the two legs.
The six-beat kick lends itself better for short sprint races, as it allows you to swim faster, but you also burn much more oxygen with your large leg muscles.
9. Don’t Put On the Brakes
When extending your arm forward underwater during the recovery, make sure to keep your hand flat and parallel to the water surface, with the palm facing downward.
By doing this, they are pushing water forward and as a consequence, slow themselves down.
10. Using a Nose Clip is OK
When you are learning front crawl, a nose clip can be useful, as it keeps water out of your nose.
Not having to worry about getting water up your nose allows you to be more relaxed.
Later on, after you have mastered the basics of the front crawl, you can wean yourself off the nose clip.
I personally used a nose clip for a year when I started swimming front crawl, and this helped me tremendously.
It is my hope that the swimming tips proposed above will help you to improve the swimming technique of your front crawl.
Some of these tips can be applied quickly, while other ones will take some time to master, but it nevertheless doesn’t hurt to give them a try.
