Castor will be the solution to the problem. You can attach this material to the heavy objects that you are about to displace and it will surely prevent you from getting hurt or from having body pain. As much as possible, use the castor with lock so that when you have found the location to place it, you can temporarily lock it to that place. Moreover, when you wished to move it again, you can still move it easily by just unlocking it. Thus, through the castors, you can avoid the different body pains that may attack you caused by forcing yourself in moving heavy objects.
