Hehehe. I'm going to list off a bunch of stuff, some of it might make sense, some of it you might be able to find on youtube. At some point I'll see if I can find some videos or put up some video.
Push-ups: ball side down holding on edges, can make these more interesting with lifting one leg. Ball side down, both hands on the ball, one hand on the ball, moving side to side with each rep of one hand on the ball, or feet on the ball, one foot on the ball and the other on the floor, one leg lifted...
Lunges: front foot on the ball or back foot on the ball
Bridges: feet or upperback/neck on ball.
Side steps onto then over ball:
here's the jumping version but you can also just step it.
Side planks: Elbow on the ball and add movement of the upper hand, eg circles, or
threading the needle, or waist supported by BoSU with legs lifted as high as you can, can add a flutter kick.
Kneeling: I love doing all kinds of stuff while kneeling on the BoSU.
Here's the basic position but you can add anything to it, shoulder presses, biceps, ball bounces against the wall... Actually the link I posted here has a play list and all the videos are pretty good and beginner friendly.
Front plank versions with ball side up or down,
here's a favorite, sometimes I add a push-up in the full plank position.
Standing on BoSU: trunk rotations with stable pelvis, arm exercises, passing a small ball from one hand to the other overhead (think jumping jack arms but with something to pass from hand to hand)...
That's all for now. I've got to get back to work.
