You have only 30min

[Doomed]

It really depends. My yellow belt lesson is thiry-plus minutes, so if I had no other choice, I would set my kick training for another time of the day and make absolute sure my strikes, blocks and stances were accounted for.

The simplest things like punches, kicks and blocks are often the most overlooked. With limited time to train, they are also one of the most productive things to practise. I also like to try to work on a point from the last lesson that I was corrected on.
