i have but its really easy to overtrain on them. Best advice is to throw in one or two at th emost into your regular routine. you dont want to be doing all supersets. If your interested in them, i have alot of variations of different kinds of supersets/dropsets and combinations of both.

If I feel my last set was crap I'll do a drop set.

dropsets yes, supersets no

Supersets sometimes, dropsets a bit more often, pause reps less often, high reps, low reps, with high sets or low sets, pre exaust set I used to think was dumb because It made you weaker at your heavy set but if you do it only once in a while it shocks your muscles and actually works. Tri-sets I never do. giant sets also I never do. Drop sets and down the rack sets are really good sometimes. There are others but cant think now.

I mix everything up whenever i feel like doing something. If I learn something new and see that it will not cause injury and might have some benefit I will give it a try. If I like it I throw it in whenever I want on top of my normal routine for something extra.

I agree that it can be very easy to overtrain using those techniques. Mind sending me or posting up those variations you were talkin about? ya got me curious
