Kyokushin Karate is a full-body contact sport (advanced training/real matches will involve you getting hit) pioneered by Masutatsu Oyama, which focuses on how gracefully your movements flow into one another but also on the power of your strikes. Moves include punches and kicks, along with blocks/deflects, prioritizing a strong body and sharp mind rather than utilizing evasive tactics.
The sensei was understanding given that it was my first time doing karate and it took me a few weeks (1 practice a week) to learn the basics, and I found that the dojo is considered a sacred but welcoming place with students from all walks of life gathered for the purpose of learning. I chose this activity to supplement my workout routine and to challenge myself in a completely new environment (karate in Japan) which normally requires you to pay close attention and listen to the instructor to do techniques correctly, but now I had to learn new Japanese phrases as well to follow along.
I have several pieces of advice, the first being to practice what you learned on your own time, even for just a bit. Returning to the dojo can be the hardest part as you don’t want to make the same mistakes as before, so practice the basics on your own time to iron out the form and be ready for the upcoming lesson. Here’s a useful link for the basics: (https://youtu.be/2_PRuRqbSLo?feature=shared)
REMEMBER, stretch first. Secondly, learn how to tie your dogi properly, it’s a sign of how prepared you really are, and it prevents your dogi from interfering with your movement. Thirdly, remember that the only way you will improve is to keep trying. You cannot give up midway as that not only stops your progress but, if you are practicing with other students, you will end up getting in their way. I only went to practice once a week, so it took me about 3 to 4 weeks to get most of the basics down. If it takes time for you to learn, don’t worry. Lastly, you should know what is expected. From my experience the positions can be a bit strenuous if you’re not flexible or not used to moving in a controlled motion and then holding a certain position for some time. For example, stretching at one point includes leg splits (no need to go all the way), and for many of the strikes you have to place your feet inward with one foot slightly in front. I’ve been running so I was not out of breath, but it would be a good idea to work on your body condition and balance. I did not know before starting that beginner lessons were more or less just practicing form and strikes, while the sparring lessons were their own class. If you want to spar, I recommend fixing your form first. When you decide to attend the sparring class, be ready to spend a decent amount on required assist/protection, and to get hit. Most lessons that would pertain to you occur in the afternoon, mine was around 8pm. If you can dedicate time, effort, and passion to learn this martial art, I recommend doing so.
