I have been doing triples up until now, but really noticed the difference recently. I took about 4 months off of lower body lifting due to a knee injury, and was pleasantly surprised to find that my numbers had not decreased very much - after a few weeks, I can pull 4 plates for a triple again, which was my old pr. Generally, when I pull, I do a few warmup sets (135x5, 225x5, 315x3) and then work up to a three rep max. My warmup sets are pretty smooth, but when I start to get into heavier weights, the second and third rep get pretty sketchy. Putting the bar down after every rep doesn't seem to do too much. I lift primarily to increase limit strength, so I'm wondering if sticking to singles might be better, and if so, how to structure my workout on pull day.
