hi!
-the gym i am a member at has a reverse hyper machine, so i just use the apparatus for that
-again, the gym i go to has sleds with harnesses, a vertical bar to put weight on the sled and a ~30m straightaway to drag them across. the sleds are metal and the floor rubber so i usually just pulled the sled with no weight added
-thee is a giant wooden wall at the gym i go to where people can throw medballs at them. i use a 15 or 16 lb medball but really only do throws that work my core in a twisting manner. i do 5 exercises with 10 reps each direction with no break between exercises but a break in between the sets
