How often do you guys lift to failure? Each set? Last set? No sets? I used to almost always lift to failure on my last set but not any more. Just once in a while. What's the prevailing theory on that?
I usually perform 4-5 sets on each of my "main" lifts. And the last 2 sets are
very close to failure, at least to 90-95% of max effort. The first set is usually warm up, and the 2nd and 3rd working sets are usually around 80%.
I have had good luck with no injuries, so I tend to keep my sets at the same percent. When trying to make all of my sets near max effort, I start straining muscles.
Now, when you talking about complete failure, like I think you are. I will only do that maybe once every 3 months or so when I max out. And I will never try to max anything with a 1-rep max. Too much risk for injury and inaccuracy. I will try to perform a lift 2-3 reps at the heaviest weight possible.
