Introduction: Advantages of Kendo practice using a plastic bottle

Kendo training usually requires large spaces and special equipment, but there are effective ways to practice easily at home.

Practicing using a plastic bottle is one example of this, and is an easy way to practice Kendo.

This method, especially when incorporated as part of daily training, has the potential to greatly contribute to skill improvement.


Introduction to Kendo practice methods that can be done easily at home

PET bottle practice uses a plastic bottle filled with water or sand to perform practice movements in place of a regular shinai.

The big advantage of this method is that you can practice at home or in a limited space.

The weight of the plastic bottle is adjustable, so you can change the weight depending on your ability and training goals.

Additionally, plastic bottles are easy to obtain and relatively safe to use, making them ideal for practicing at home.


How practicing swinging a plastic bottle contributes to technological improvement

Plastic bottle practice is an effective training method for honing the basic movements of Kendo.

You can practice the basic hand position, arm movement, and body swing when using a shinai.

In addition, the weight of the plastic bottle can be used to improve precision in the details of kendo techniques, such as how to transmit force during strikes and how to maintain zanshin at the end of the swing.

Furthermore, regular practice swings contribute to improving the muscular strength and stamina necessary for Kendo, which directly leads to improved performance in matches.


In this way, practicing swings using a plastic bottle contributes to improving Kendo techniques in many ways, and is recommended as an effective method that can be easily practiced at home.

By incorporating this method into your daily practice, you can expect to steadily improve your Kendo techniques.



Basic method of swinging a plastic bottle

Practicing kendo using a plastic bottle is one of the easy ways to practice kendo at home.

Here, we will explain how to prepare a plastic bottle, how to use it safely, and basic practice swing forms.

Proper preparation and form will enable you to train effectively.


How to prepare and safely use plastic bottles

When preparing a plastic bottle for kendo practice swings, it is ideal to use a 1.5- to 2-liter plastic bottle.

Add an appropriate amount of water or sand to the plastic bottle to give it a sense of weight.

In the case of water, fill the plastic bottle about half to two-thirds of the way, so that it feels solid but still has a manageable weight.

For safe use, it is important to make sure the cap is tightly closed and to periodically check the surface of the plastic bottle for cracks.

Also, make sure that the space in which you practice swings is large enough to avoid bumping into other people or objects.


Basic practice swing form and points to focus on

The basic form of plastic bottle practice is the same as regular kendo practice.

First, spread your feet shoulder-width apart and bend your knees slightly. Grasp a plastic bottle with both hands, swing it over your head in one motion, and then forcefully swing it down.

At this time, by firmly using your hips and putting your weight on the swinging motion, you will be able to exert your strength in a way that is more similar to actual combat.

The key to practice swinging is to swing the plastic bottle so that it passes through your center line, and to keep your wrist steady when swinging down so that the bottom of the bottle is pointing precisely toward the target point.

Also, don’t forget to maintain Zanshin firmly in order to stabilize your posture after swinging down.



In this way, practice swings using a plastic bottle are not only useful for improving kendo techniques, but are also effective in resolving the lack of daily exercise.

Try incorporating this exercise into your daily routine while remaining safe.

In particular, you can strengthen elements that contribute to maintaining correct posture and movement, and improving hitting power and speed.

Here, we will explain in detail how PET bottle practice improves these technical elements.


Maintaining correct posture and movement

Practice swinging with a plastic bottle is especially effective for maintaining correct posture and movement.

By adjusting the weight of the plastic bottle, you are required to maintain the posture unique to kendo for a long time, which leads to even use of all the muscles in your body.

When performing practice swings, it is important to keep your back straight and lower your hips properly.

Also, when swinging down, be aware of the coordination of your arms, shoulders, and hips, and you will be able to perform the series of movements smoothly.

By repeating these exercises, you will naturally acquire the basics of how to use your body in Kendo.


Improving hitting power and speed

By using a plastic bottle, you can easily train to improve your hitting power and speed.

By increasing the weight of the plastic bottle, more force is required, which naturally improves your striking power.

Gradually increasing the speed of your practice swings will also improve your reaction speed and hand speed.

When practicing swings with speed in mind, pay particular attention to the acceleration of the downward swing, aiming for a fast and powerful blow.

Through regular training, you will be able to perform these movements naturally during matches, which will directly lead to improved performance in actual matches.


By practicing plastic bottle practice, you can effectively train the technical elements of kendo.

Maintaining correct posture and movement, and improving striking power and speed are extremely important techniques in Kendo, and by continually practicing these techniques, you will improve your overall Kendo techniques.



Practical practice of practicing plastic bottle techniques

Practice swing practice using a plastic bottle can cover a wide range of exercises, from basic movements to advanced techniques.

This section explains how to practice combos that combine multiple attacks, and how to change your practice swings according to different situations.

We aim to use these applied technologies to improve our ability to apply them to kendo matches, making it possible to respond more practically.


Practicing combos that combine multiple attacks

Rengo in Kendo is a technique in which one attack is blocked and then quickly moves on to another attack. When practicing a series of moves using a plastic bottle, you first perform one action (for example, men-uchi), then immediately move on to the next action (for example, toko-uchi), repeatedly. This exercise includes the following steps:

  1. Create a flow of consecutive attacks : Learn the movements to smoothly transition from the first attack to the next. It is important to use the weight of the plastic bottle to apply the appropriate force and speed to each blow.
  2. Increase precision and speed of movements : During a series of attacks, each movement must be precise and executed quickly. While gradually increasing the speed, try to maintain accurate hitting points.


Changes in practice swings depending on the situation

A variety of situations arise in Kendo matches, so the ability to change the practice swing method according to the situation is also required. When practicing with a plastic bottle, you can perform practice swings based on the following situations:

  1. Counterattack from defense : Anticipate the opponent’s attack and perform a practice swing that immediately turns into a counterattack after a defensive move. For example, you might retreat once while avoiding an opponent’s attack, and then immediately move forward and pretend to counterattack.
  2. Attacks at different distances : Distance is important in Kendo. Using a plastic bottle, you will practice changing your practice swings depending on the distance, such as short-range thrusts, mid-range men-uchi, and long-distance body strikes.



These applied technique exercises can be performed very effectively even using a plastic bottle, and are expected to significantly improve your ability to respond in an actual Kendo match.

With practice, you will be able to handle more complex situations and expand your skills.



Points to note when practicing swinging with a plastic bottle and how to avoid trouble

Practicing kendo practice swings using a plastic bottle is convenient and effective, but if you don’t do it correctly, it’s not only ineffective, but can also cause injury.

Below you’ll find common mistakes that can be made while practicing, how to correct them, and specific advice on how to practice safely.


Common mistakes during practice and their corrections

  1. Using the wrong weight : If you put too much water into the bottle, it will put too much force on your swinging motion and cause strain on your shoulders and arms. On the other hand, if it’s too light, you won’t be able to train effectively. To find the right weight, adjust the amount of water little by little to find the weight that works for you.
  2. Inaccurate form : When practicing practice swings, you may find your posture is poor, or your swings may be too big or too small. To maintain proper form, practice in front of a mirror and check your movements, or record a video to review later.


Specific advice on how to practice safely

  1. Securing an appropriate practice space : In order to safely practice practice swings, there must be sufficient space around you. Choose a large space to practice so that furniture, walls, and other people will not be damaged by your practice movements.
  2. Use appropriate equipment : Wear appropriate athletic attire when practicing, and choose non-slip shoes or slippers for your feet. Also, consider using non-slip gloves as your hands will often get sweaty.
  3. Warm up and cool down : Warming up before practice and cooling down after practice are very important for injury prevention. Warm up your body with appropriate stretches and light jogging, and take time to relax your muscles after practice.
