Kettlebell Training

Breathing is an important key to performance. If you neglect it, you leave a big piece of the performance puzzle on the table.

If your mission (like mine) is to reach the apex of your physical potential—or get as close as possible—you should consciously use your breathing to reach your goals.

Why is breathing so important?

Our nervous system is divided in two parts: the autonomous nervous system and the cerebrospinal nervous system. These are complicated words for a fairly simple distinction. The autonomous nervous system (ANS) basically works on its own. Some of the tasks of the autonomous nervous system include your heartbeat, digestion, metabolism and the workings of your internal organs.

The other part of the nervous system, the cerebrospinal nervous system, is the part we are concerned with in our training. It enables us to consciously interact by:

• Perceiving our surroundings with our senses
• Reacting with the muscles in our bodies

If you ask a doctor, he probably will tell you that breathing is a function of autonomous nervous system that runs quite fine without conscious interaction on your part. While this is an objectively correct answer, it is not the whole picture. Unfortunately, many trainers leave it at this, and are ignoring the huge potential for performance enhancement.

The problem is, your autonomous nervous system does not know about your plans or your situation. The ANS reacts instinctively on perceived threats—if you encounter a dangerous situation, the ANS releases adrenaline to raise your heart rate, increase your breathing frequency, and to prime your muscles for the fight and flight response. This mechanism helped our ancestors survive to produce the next generation. However, the ANS reaction is not always the best option—especially not for athletic endeavors where energy management is often critical for success.

The RKC Snatch Test is one of those situations where breathing can easily fail you, if don’t take control. Anybody who has taken it knows that it is a staggering experience. Your energy consumption suddenly goes through the roof as a heavy iron kettlebell beats down on your body. If you are not accustomed to it, your nervous system will perceive the situation as an immediate threat, and trigger an adrenaline reaction. Initially, this will help you to use more of your strength. But if you do not take control, you will overexert yourself in the first three minutes, and probably fail in the end—or at least it will make it all much harder than necessary.

The benefits of taking control of your breathing:

• It allows you to consciously manipulate certain functions of your autonomous nervous system (i.e. keep your heart rate down).
• It ensures you do not prematurely overexert yourself.
• It gives you extra power when you need it.
• It helps you to relax.
• It quickens your recovery.

How to do it correctly…

In the RKC, we have explicit instructions for breathing in each of our main exercises. The basic idea is to inhale during the negative phase of a movement, where the least power and stabilization is needed. The short and forceful exhalation should optimally be timed with the moment of highest demand in power and/or stability during the active phase. This principle creates a very distinct rhythm for each exercise. The two major categories to differentiate exercises are ballistics and grinds, but individual exercises also benefit if the breathing pattern matches the exact demands.

The Inhale:

There is a saying in the martial arts:
“When your opponent inhales through his mouth, victory is almost yours.”

I’ve made this observation in many sparring matches. Whenever I see my opponent’s mouth opening, I throw a few fast kicks and punches his way. Usually, the match will be over in seconds. My Taekwondo grandmaster, Son Jong Ho, even stated only the first and last breath should be through the mouth.

Practice nose breathing deeply into the abdomen to create pressure below your navel. When you use this technique in a kettlebell session, you will be able to keep your heart rate much lower, which will give you more endurance and power. When you begin to practice nose breathing, you will soon feel the urge to open your mouth, but try to resist it! The longer you practice, the better it will feel.

A little experiment: Lie on your stomach with your forehead resting on your hands. Inhale deeply through your mouth. You will feel your chest expanding during each breath. Now switch to breathing through the nose. You will immediately feel your belly pressing into the floor and your chest will stop heaving. The difference is that while breathing through the nose, your diaphragm will pull your lungs down into your abdomen, increasing the pressure in your lower abdomen. If your core muscles are engaged—as they should be whenever you touch a kettlebell, this will lead to much more core stability and therefore safety. On the other hand, an inhalation through the mouth mainly engages the chest and shoulders. If those muscles are tensed during a kettlebell swing, your breathing will be severely constricted. If you need more oxygen while breathing through the mouth, you will need to inhale more often, reducing the time oxygen will be processed in your lungs. Eventually, this will lead to hyperventilation and a breakdown of your performance.

Pressurized Exhalations

Breathing is a very versatile tool. When used correctly, it can benefit you in many different situations. For our purposes, we need it to enhance stability and power during our kettlebell workouts.

We use short, pressurized exhales like hisses or shouts to increase tension and avoid losing too much air. If you fully exhale, your abdomen is completely emptied and your core muscles have nothing to hold against. Imagine a car tire. When it is filled with the correct pressure, it is hard and sturdy, but the stability goes away when it starts losing air. Stability is completely lost when it is empty.

When exhaling during kettlebell drills, do it with your lips almost closed and the tongue pressed against the roof of your mouth behind your teeth. If this makes a hissing sound, you are doing it right.

Breathing Patterns for the RKC Kettlebell Exercises

As each exercise demands a different pattern of stability and power, the optimal breathing pattern for each exercise will also be different.

Breathing for Swings

The most basic ballistic kettlebell exercise is obviously the swing. This exercise gives the kettlebell its unmatched effectiveness and safety.

The passive phase of the swing, when the kettlebell drops freely from the apex of the swing, requires almost no effort until it is caught in a deep hip hinge. Therefore, this is the time for a deep inhale to the lower abdomen, the area where we need the most internal pressure. This also provides the necessary stability during the catch. For the optimal intra-abdominal pressure, you will need to inhale through the nose. When you start practicing this, you might get the impression that you are not getting enough oxygen, so take your time and adjust the intensity of your training. With practice, you will find that you can inhale much more deeply and get much more oxygen.

When catching the kettlebell from the drop, hold your breath for maximum intra-abdominal pressure. The exhalation should be as short and forceful as you can make it and timed exactly for the moment when your hips lock out at the top of the swing. In the kettlebell swing, the time between the hip snap and the moment when the kettlebell reaches its apex is almost identical. It will be more explosive if you focus on synchronizing the exhale with your hip snap.

Breathing for Cleans and Snatches

The basic movement pattern of the clean and snatch should be identical to the swing. The inhalation and exhalation also follows the exact same principle. Be aware that with the snatch (especially) there is significant time between the hip snap and the arrival of the kettlebell in the overhead lock out. The right timing will make an even bigger difference than in the swing.

But, there is also another difference between the swing, and the clean and snatch that we need to consider for the optimal breathing pattern. This difference is the built-in pause at the top position of both exercises. While the swing is a closed-chain exercise (meaning that every rep is immediately followed by the next without a discernible pause), the clean and snatch are not. After the initial rep, which starts on the floor, each clean or snatch starts and ends at the top. How you handle breathing with this pause will depend on the context of your workout and the exercise.

If you do short sets of snatches for instance, you can simply hold the air and wait for the drop. In a situation where you are doing many snatches in a short time (i.e. Snatch Test) you might need to use this pause to exhale more, thus enabling you to refill with more fresh oxygen. You could even decide to prolong the pause for additional breathing cycles to combat oxygen debt.

If you clean for reps, then you can use the same strategies as in the snatch. If you clean for squats or presses, you should hold your breath in the top position to conserve the tension from the clean.

Breathing for the Get-Up

The get-up is an exercise category in itself, and it needs it very own strategy for breathing. The first challenge is that the get-up (including get down) takes at least 30 seconds (though 60 seconds is recommended). Either way, you will obviously need to breathe several times during one single rep. The second challenge is not to lose tension within the entire rep. To accommodate both demands, you need to shallow breathe while keeping your abs tight at all times (breathing behind the shield). The hardest parts of the get-up are the transitions from one position to the next. To give you the necessary strength, time small but pressurized exhalations with each transition. Refill (inhale) through the nose when you are in a static holding position.

Breathing for Presses

Military presses are high tension drills. The more tension you generate, the stronger your press. As already mentioned in the section on the clean, it is essential to conserve the tension generated from a good clean for your press. Make sure not to exhale while you catch the kettlebell in the rack position. Depending on the cardiovascular effort, you may wish to refill your lungs by inhaling again before you actually start the press.

For the press itself, the breathing pattern will depends on your objective:

• If you press a light to medium kettlebell for high reps, exhale on the way up, and inhale on the way down.
• If you are working with a heavy weight, exhale on the way up, inhale while the bell rests in the lock out, then exhale again while you are actively pulling the kettlebell down. Obviously, you will need to inhale again before you start the next rep.

The inhalation for the press should be through the nose to the lower abdomen as already explained for the other exercises.

The exhalation will last longer than in the ballistic exercises, but will require even more pressure. Make sure not to lose too much pressure!

Breathing for Squats

For a fairly simple exercise like the squat, it is funny that the breathing pattern is (in my opinion) the most complicated for all RKC drills!

First, let’s analyze the squat:

• Usually you start with a clean. Do not lose air while catching the kettlebell.
• Lower yourself into the squat.
• Hold the lowest position until the downward momentum dissipates.
• Press yourself back up to the standing position.

The moment you start to rise from the deep squat position (like in the deadlift) is when you need to get the dead weight moving again. It is also when you need to be strongest. To give you some extra tension, initiate the ascent with a forceful grunt followed by a short pressured exhale on the way up.

The purpose of the grunt becomes obvious when you squat heavy, but practice it even with light weights, so you build a habit for when it counts.

During the descent, you will need the least strength. But to best prepare yourself for the ascent, your abdomen should already be pressurized, and you need to get as tight possible. It is easier to fill your abdomen while it is not under strain, so inhale deeply while still standing then hold your breath during the descent.

Breathing During Rests

In the last section, I wrote about breathing while performing kettlebell exercises. If you did not control your breathing during your kettlebell work until now, using the above information will improve your performance considerably. However, there may still be a missing link to your overall performance: breathing patterns for rest periods or in between sets.

The better your breathing pattern fits the demands of your chosen exercise, the more power you can produce and the more continuous reps can you do.

When you set the kettlebell down and release the tension, your body will immediately try to reduce the oxygen debt. For reasons unknown to me, the preferred method to increase the oxygen intake is to suck in air through the mouth. The higher your oxygen debt is, the faster your breath will come. The problem with this method is that it leaves you winded until your oxygen has leveled out. For a martial artist, this would be a good way to lose an encounter. In kettlebell training, it leads to longer recovery periods and a reduced overall work capacity.

Whenever a candidate decides to set the kettlebell down during the RKC Snatch Test, breath control is the crucial factor for the outcome of the test. Almost all candidates who give in to the reflex of sucking air in through the mouth will fail their test because it will take them longer to start snatching again.

Between Sets

Immediately after you set the kettlebell down, the need to suck in air is the strongest. You may even have a sensation of choking! If you open your mouth and start sucking in air, the feeling subsides almost immediately, but it becomes very difficult to return to controlled breathing once you let that happen.

My suggestion is to leave your mouth shut and inhale deeply from the nose down into your groin. If you can stand it, also exhale through the nose. If not, let the air out from your mouth, but close it again before the next inhalation.

With this strategy you can start your next set much faster and keep your heart rate considerably lower.

After Your Training Session or Long Rest

If you opt for longer rest times or have finished today’s workout, the goal is not to start your next set sooner, but to get the most out of your recovery time and release the tension you accumulated. When your oxygen level is back to normal, keep breathing deeply, inhale into the groin and try to exhale slowly while letting loose all tension. You can even close your eyes and focus completely on the airflow through your nose. This will speed up your recovery.

HardStyle Breathing

The techniques I described in this article are by no means the ultimate solution or the only right way to breathe. As mentioned above, breathing is an incredibly versatile tool. There are many breathing techniques out there that do wonders if executed properly for the right purpose. The techniques I’ve described are explicitly aimed to make your kettlebell training safer and more effective.
