title: The roles of the partners in pair work
date: 09-Mar-2026
"OK, now partner up and give that a try..."
A line heard in almost every dojo, kuen, dojang or training hall worldwide - but how much time is spent understanding what the two roles in partner work are actually meant to do?
In traditional Japanese arts (koryu - literally 'old school') this is usually very well explained, in most other systems not so much in my experience, and I've spent more than thirty years dabbling in various arts and training in various schools.
In Aikido these roles are often referred to as 'uke' and 'nage', literally 'receiver' and 'thrower'. In kendo and other sword arts these are referred to as 'shitachi' and 'uchitachi', performing sword and receiving sword.
The 'receiver' is often treated as a passive partner, or one who just initiates a simple attack (a static grab or a single punch or kick) in order for their partner to have a chance to practice the technique being trained. A little more than a heavy bag, but not much. Typically the instructor calls for a student to come forward and 'take the fall' while they demonstrate the technique to be studied in front of the class.
For the purposes of our discussion we'll call them receiver and performer. Whilst in most modern arts (Aikido, Judo, Kendo, Karate etc.) the performer is often the more experienced partner, starting with the instructor in the initial demonstration, and the receiver is the more junior. In many arts the partners swap roles during practice.
In koryu arts, practice is the complete opposite: the more senior partner is the receiver, and the more junior is the one performing the technique - all training is done in this fashion, with the senior setting the pace and providing the cues for the junior to perform the correct techniques. Training is almost completely one-to-one, unlike modern arts which have adopted training techniques to cater to school-room or military-style training where large numbers of students need to be trained simultaneously.
With this difference in mind, let's talk about the roles and their responsibilities in our practice.
Firstly, safety is key - it is the job of the performer to keep their partner safe - my instructor always says "If you break your training partner, you don't get another one!". It is also the job of the receiver to move with and ahead of the technique in order to safely absorb the force within their body and to, when needed, break their fall. The word for break-fall in Aikido is 'ukemi', which literally means 'receive with the body', which makes no mention of falling or the ground, which may or may not be appropriate.
It is neither up to the performer or the receiver alone to set the pace or level of the practice, but is rather a collaborative agreement between them. Most accidents in training are due to this not being formally and verbally agreed. Partners need to be constantly providing feedback on whether the pressure needs to be dialled up or back in order that the performer is effectively learning and the receiver is able to receive the technique safely. Both parties need to be relaxed, once the threshold of a partner's limit is passed they will stiffen up, mentally and physically, and no more learning will be taking place. This is the accident zone, and is to be avoided.
The receiver must give a genuine attack, a grab must have an appropriate level of force and intent behind it, a punch or a kick must be at an appropriate speed for the partners and be on target. Distance and timing must be accurate. If the attack is not genuine, effective learning is compromised.
This is not sparring, it is co-operative learning. The point is not to win, but to learn, for both partners. Sparring is something very different, and is not addressed in this post. That doesn't mean that practice is weak, unfocused or without intent.
To sum up:
- Safety is paramount - you can't practice if you or your partner are injured - you keep each other safe;
- Partners when they practice together must agree a level of pressure that is appropriate for their unique pairing, and constantly increase or decrease this according to feedback, both verbal AND non-verbal;
- The receiver is far from passive, they set up the correct situation for their partner to perform the technique, they receive the technique with their body safely, and they do not move unless their partner moves them, i.e. a genuine reaction, not a pre-emptive fall or giving in;
- If either party starts stiffening up, getting defensive, panicking, then stop - and dial it back.
I hope this helps - train safe!
