7 . stand up sit down ,,, yeah this seems pretty straight foward , stand up and sit down as many times as can until your legs cannot hold you up any longer ... work your way up to doing it with 1 leg at a time!
8 . seated quater dips . just put your hands on the sides of your chair and lift yourself up and down
9 . seated incline dumbell press ... now if your chair can recline back, do it ! then start pressing . but make sure the chair is stable u dont want it going too far back ..
10 . incline flys .. same thing
