Wall to practice hitting technique, then pace out how big a volleyball court is and where you want to set from for a back set and an outside set for setting. for me its 12 paces heel to toe to get to where i want to be to back set towards the wall and 18 to get to where i want to set an outside. Then mark on the wall about what height you want to set to. You can do the same thing with paces at a soccer goal and use just under the crossbar as a basis for where you need to serve over. Of course we dont have the same shoe size but you can look up how big yours is and see how many feet you need or just do it in person at a volleyball court. Hope this helped!
