i used a basketball for ski squat...

and for those descriptions, use google please, i'm lazy to write now, i skipped crossbody, but scissor is a good exercise, you lie on the floor and put both legs on a chair, you just bring your nonworking leg to your chest and push your working leg on the chair to make your hip leave the ground at the same time.
