Whipback has a pretty good list.
I do these things for abs called "uppers and lowers". gymnaSTICKs on here taught me how to do them so maybe she could post and explain.
I do a lotta different kinds of pushups because they are easy to do anywhere. Triangle, regular, wide arm, with feet on something, clapping, where you hold the halfway position.....use your imagination!
I would also add lunges and wall sits (make it even harder with a partner sitting on ur lap) and running stairs/hills to whipback's list too for legs.
I usually try to condition with a partner because it makes it more fun. And a lotta times i'll condition during TV commercials...pick an exercise and do as much as u can when commercials are on until the show comes back on. Then next time pick a different muscle group.
Good luck!!
