As long as cheating is not the norm and cheats are used at the end of a set or the last set, it has it's place. The article states that and I think it is important to reiterate for the newbie.

You can also keep the form and use drop down sets as many of the Olympians have done. I think for breaking plateaus and bulking, yes. But we have all seen those persistent swayers who want to look like eggs. Uuggh!
