We've been doing push-ups and Jujitsu sit ups consistently at the beginning of classes. At the end. we do "opas" and standing for a minute or so in a horse.
In the middle, we do forms and some other exercises. Last week it was "referencing" across the floor in a horse and power (forward) stance. ("Referencing" is just putting your feet together as you step, but I should them how to use it offensively. See examples here .) This week it was shuffling (this video is perfect BTW) and kicking a shield.
