Heian Nidan

The second Heian kata has several simultaneous block and strike techniques, it has side snap kick and front kick. 

Heian Nidan is more complicated than Heian Shodan, so time needs to spent on the individual combinations within the kata, for example the first 3 moves, then the next 3 moves, focusing on sections of this kata, then putting the sections together is a great way to learn this kata.
