Click the Seminar tab for more details.

The Atlanta School of Aikido offers a style of Aikido based on the teachings of Koichi Tohei's Ki Society, Shihan Shizuo Imaizumi's of Shin Budo Kai Aikido, Mark Leidig of the School of Inner Martial Arts, and Dan Harden's Sangenkai. It is movement based, flowing and smooth, but true to Aikido's martial roots.

Training includes the empty-handed arts of Aikido (throwing and pinning) as well as Ki training, weapons training with jo (staff), bokken (wooden sword), and Internal Power development.

Classes are small and focused on personalized instruction. Beginners train with experienced students or an instructor at the start of their training.

It is our hope that you will come by and visit one of our classes.

Phil began his study of Aikido in 1996 with Sensei Feldman. Prior to this time, he had an interest in martial arts, but never commited himself to formal study. Under Sensei Feldman's teaching and guidance, Phil slowly progressed from someone with no skills to the level of Shodan in 2006. The journey has been exciting, both physically and spiritually. He derives great pleasure from applying the skills he has learned under Sensei Feldman and Sensei Leidig in his teaching of beginning students.

Mitch was promoted to Shodan in 2007. In addition to Aikido, Mitch has studied archery and western fencing, particularly epee and foil.


Hector Viust - Nidan (2nd degree black belt)
Primary instructor for the Thrusday night class.

Hector began his Aikido journey in 2009. While he has practiced other forms of martial arts prior to joining the Atlanta school of Aikido, he has never committed to any particular martial art. However, under Sensie Larry’s guidance, he was able to find his path through Aikido. “Aikido has allowed me to practice a martial art that does not conflict with my thoughtful nature. It has been an enlightening experience to be able to deal with conflict in a compassionate manner.” Hector looks forward to continuing his Aikido journey and sharing his experiences with others.

Hector was promoted to Shodan in August 2014.

“As I look back upon my Aikido career, I feel that I was extremely lucky to have come upon and chosen The Atlanta School of Aikido as my guide in my martial arts journey. The knowledge, depth of understanding, commitment and most of all patience of the instructors have been supremely beneficial to me. I highly recommend this school for your journey as well and look forward to training with you on the mat”

How to Find a School

Most people pick a school because they drive by it on the way to the dry cleaners.

Often times I get asked for recommendations for a kids class, or how to find a place to practice. It's a good idea to treat a search for a martial arts instructor much like you would a search for a physician or attorney, and ask people you know or trust for a recommendation.

A few simple questions to consider:

  1. How the beginners are treated by the teacher, and how they are treated by the senior students?
  2. Do you think you can learn from this instructor?
  3. Are you willing to spend 2-3 days a week with these people in this environment?

One of the great secrets in the martial arts is that there are people, and schools who practice because it is something they love to do. They are usually smaller in attendance, allowing for a more personal teacher/student, artist/apprentice relationship which is how martial arts have traditionally been taught. On top of smaller classes, many times these school charge less than more commercially oriented schools. But they can be harder to find, since they don't always have that big sign on the freeway.

Why should you watch a class before starting our class?

Because I am more interested in your time than your money.

As a school we invest a lot of time in beginners. New students are paired with experienced students or an instructor until they reach a level of proficiency and confidence in their own abilities. Working with a partner who knows what they are doing, won't injure you, and won't let themselves be injured provides the safest environment for beginners. Learning is also easier when your partner has the knowledge and skill required to do the techniques being taught. For these reasons a more personalized approach to beginners is far superior to an 'introductory class', but it asks a lot more of the experienced students to support it.

Advanced students get a chance to learn how to teach, but it takes them away from the more advanced training. Instructors also spend more time watching and instructing beginners than a regular class.

We only require 1 month's dues to start training, and make this investment in you. Since watching a class will help you make a more educated decision about whether practicing Aikido with us is the right thing for you - we ask that you invest an hour and a half to help you make the right decision.

Benefits of Aikido

Aikido Benefits the Body

Besides being a full-body workout, Aikido provides many benefits. These benefits Include:

  • Strengthing most muscle groups including core muscles.
  • Improved balance both at rest and in motion.
  • Improved "connectedness" in the body. Some may call this coordination, but it is even more than that.
  • Increased flexibility through dedicated stretching and normal practice.
  • Learning to fall and roll. That's right, it's a benefit! Many students have come to class and said that their skill in falling and rolling had saved them from broken bones or worse when falling from a ladder, stairs, or the like.
  • Easy on the body. Unlike other arts that damage and wear down the body over time, Aikido, as we teach it, can be studied and enjoyed for a lifetime. There is no "smash and crash" here.

Aikido Benefits the Mind

While Aikido is a good workout, it has many benefits for the student's mind as well. Particularly, Aikido views the mind and body as connected and integrated. Therefore, practice builds and stimulates that connection. Here are some of the benefits:
  • Increased focus and awareness.
  • Being centered and in touch.
  • Relaxation and stress relief.

Aikido Benefits outside the Dojo

While Aikido offers many benefits to the student while studying in class, there are also many benefits to be realized outside of class as well. They include:
  • Self defence. Aikido is a martial art after all.
  • Conflict management and resolution. Many principals learned in Aikido apply to all types of interpersonal interactions and conflict. The principals apply whether the conflict is physical or some other type.
  • Peace and harmony. Though it is often misunderstood in its martial context, Aikido teaches the restoration of harmony. The regular practice of seeking harmony rather than destruction is a positive influence in everyday life.

Internal Power

Atlanta School of Aikido teaches Internal Power development as taught by Dan Harden and his Sangenkai organization.

Dan learned Internal Power in Daito Ryu Aiki Jitsu and made a personal journey out of applying these principals in MMA and traditional Japanese Swordsmanship. The principals apply universally across Yoga, Tai Chi, Aikido Daito Ryu, Hsing I, and Bagua. The commonality of these arts is based on spiral movement.

Dan will quote O'Sensei (the founder of Aikido and legendary martial artist); demonstrate the bodywork O'Sensei was referring to; and show it's application in not only Aikido but other martial arts.

Very few people in the world can generate the power Dan Harden demonstrates. Even fewer can teach it in a coherent, systematic way.....in English.

We practice Internal Power development with solo exercises, paired practice, and ultimately integrated into Aikido. Here is what one of our students has experienced with Internal Power practice.

"Before starting Aikido, I had an injury to my hip, resulting in daily discomfort and limited mobility, including an uneasiness about my ability to perform some of the techniques required by Aikido. However, after 2-3 months of performing the bodywork exercises, the discomfort in the hip disappeared and I regained full confidence in my physical ability."
- Joe M.
