This video shows at a basic kata-based limb-control drill. The methods contained within the drill can be found in many kata including Gekisai-Dai-Ni, Chinte, Chinto / Gankaku, Niseishi / Nijushio, etc.
It is important to remember that this is just one of many drills, and the methods within need drilled individually, in alternate sequences, and in differing contexts. It is also important to drill the methods live and give them free-rein in live practise.
It is when these methods are integrated into such a wider training matrix that they will become applicable in live situations and the value of kata will become fully realised.
All the best,
