The high peterson step up is just a step up like the normal ones but your box is higher, im not sure how high though. And the twisting lunge is just a lunge forward with a twist at the waist like this... YouTube - Medicine Ball Twisting Lunges Med Balls Exercise

Although i think for the lunges you twist both ways. (side to side)
