A Heian Shodan exercise

Here's a kata/combination exercise I sometimes do at our club. First of all, do Heian Shodan. Next, do it again, but this time, before every oi-zuki, put in a mae-geri with the step (eg. gedan-barai, mae-geri, oi-zuki). On the third run-through, as well as the mae-geri, add a gyaku-zuki after each age-uke. Do it again, with all the previous additions, but now turn each oi-zuki into sanbon-zuki. Finally, after each shuto-uke, add a kizami mawashi-geri. It's a great warm-up exercise, and good kihon combination practice.
