One question per series
Choose a verifiable criterion: the path of an arm, the arrival of a foot or the balance after a pivot. A slow test makes observation easier; a more lively test makes it possible to check whether the organization remains coherent. Repeating a fault without specific feedback does not guarantee progress. Describing “my back foot moves at the end” gives a more useful lead than “I lack power”. The teacher adjusts the amplitude and difficulty to the practitioner.
Connect the dimensions of practice
Find the gesture in a kata, then in a controlled instruction with a partner. This provides information that is absent from work in a vacuum: scope, moment of action and reaction. Conversely, the kihon allows you to calmly correct a detail seen in the exchange. This circulation between exercises avoids treating kihon, kata and kumite as three unrelated disciplines.
Build a repetition that provides information
A series becomes useful when the practitioner knows what he is looking for and how he will recognize an improvement. For a step with oi-zuki, we can observe the moment when the foot arrives and the moment when the fist finishes its journey. A few slow tests allow you to spot a shift. The teacher then chooses whether this discrepancy must be corrected in the proposed exercise. Alternate careful repetition and repetition at the requested pace. The number of trials comes after the quality of the instructions: a long series without criteria can above all reinforce a habit.
Move from isolated gesture to a sequence
Start by identifying the supports at the start and finish. Then add the movement, then a second action. Check that the first technique leaves a position allowing the next one. This work reveals a frequent difficulty: succeeding in each gesture separately, but losing the organization between the two. With a partner, distance can modify the route or the moment of action. The result is therefore not judged solely on a final silhouette. A good correction specifies the context in which the gesture must work.
