Oh god, jump squats BY THEMSELVES are ass kickers.

As for the stomach exercise, we will go back and forth for... god, I'm not sure how long she makes us do it. We do it quickly and for a while, almost to the point where we're like, "really?" and then she makes us go into tabletop for a few counts. At least 8. She counts slow. At least, it seems that way in tabletop. And then doing plank pose with your hands on the ground or doing it with your forearms on the ground are good ones. I like doing it on my forearms because I don't strain my wrists. We do a lot of plank in my yoga class too. It's good for getting a lot of your body to work at once.

Also. A common exercise that I'm just not comfortable with: lunges. I can do them, I benefit from them, but I'm awkwardly coordinated with them. During kickboxing, the trainer wanted us to go down into a lunge, while weights were in our hands, front kick with the back foot, and then go back into the lunge. I thought I was going to fall ****ing over. I've got strong legs and good balance, but lunges **** me up. Maybe because I can't see that foot and I don't trust that I'll land properly, I don't know. But it's pretty frustrating.
