Many Karatekas, all over the world, understand the importance of Stretching in Karate but there's a huge problem.

The problem is... they are using inappropriate Stretching exercises with the wrong kind of students. They're loosing precious time searching for reliable information but they only find disperse and trendy tips from "experts"...

They don't have a plan of action.

They're teaching without the proper guidelines.

And what's even worse, they have no concrete processes to take the most of out their students, no matter if they´re Traditional Karate Students or Sports Karate Athletes.

Karate Senseis just don't have the time to follow the pace of scientific research, right?

That's why we create the Flexible Karate Online Course..."Oh, heck no, this isn't for me..." Hear me out.

I teach Karate for more than 17 years and practice it since I'm 12 (I'm 36, right now)... And I (as you, I believe) always tried to give my students the most effective, safe and motivating exercises.

"The full access to all the research about Karate, Combat Sports and Human Movement."

So, I went to the Master of Science in Sports Training - Specialization in Karate (Faculty of Human Kinetics - University of Lisbon, Portugal). I learned a lot from top-level teachers and researchers and you know what was the most important foundation I bought from there?

The full access to all the research about Karate, Combat Sports and Human Movement.

And one of my first big interests, when I started diving deep into the best online scientific databases, was Flexibility Training. How would I help my students increase their Range-of-Motion?

I have students with 5 years old, 15 years old, and adults… I have those who practice every day and those who just train twice a week… I have very stiff students but also highly flexible ones…I have Karatekas with good levels of Hamstrings’ Flexibility but terrible executing High-Kicks or a Shiko-dachi.

So, I put into the work and gathered all the Original Research, Systematic Review and Meta-Analysis about Stretching, transforming it in practical and easy-to-follow knowledge… and now, I can consult it whenever I want, in my smartphone or in my computer! Guess what? You can too.

Get all the scientific-backed knowledge about Flexibility Training and the most relevant methods and exercises to improve it (based on +200 Scientific Sources)

Why Should You Trust Us?

In Karate Science Academy, we follow several criteria and international standards before we give you practical and useful information. Let's see it more in-depth:

  • We search only for Original Researches, Systematic Reviews, and Meta-Analysis in dozens of scientific journals.
  • We only consider Scientific Publications that follow a peer-reviewed system.
  • When we find one article that is unique about a subject, we only take it in consideration if it’s very robust and/or complements reliable knowledge that already exists.
  • Regarding training protocols, we only consider research that includes Control Groups so we can compare the results of the group that performed the tested protocol with the group that didn’t do it.
  • Training protocols must be 100% clear, with all the details.
  • The population that is submitted to a given training protocol must be explained in detail.
  • When necessary, we submit the Scientific Sources to 1 or more of 3 quality-testing tools: PEDro’s Scale, Cochrane Risk of Bias Tool or ROBIS Tool (Risk of Bias in Systematic Reviews)

Of course not! For superficial tips, you have a bunch of places to go (especially online). Flexible Karate will teach you everything you need to learn about a theme in a simple and practical way.

If you find out that what you have been training for many, many years is scientifically wrong you have two options: 1) you change to the right path, no matter what; 2) or you choose to continue following your Master.

But remember that if your Master is not open to evolution and knowledge maybe he or she isn’t a true Master 🙂

No! Flexible Karate was created exactly to take Scientific Research to every Sensei, no matter the educational degree. As long as you really want to learn you’ll grow with Flexible Karate…

Yeah! We feel the same way… That’s why Flexible Karate was created. To differentiate real knowledge from the noise!

No! Flexible Karate is for the Senseis that really want to step up to the next level of knowledge about Karate training. If you are only searching for superficial tips or miraculous methods you are in the wrong place!
