I have been power lifting (deads, squats, bench, OH press) in addition to beach lifts for 10+ years. I have never needed 30-45 minutes to warm up. Ever. I have also never been hurt lifting. It is much safer than the stupidity I see with XFit.<p>The key is good form and gradually warm up to work weight. I was doing okay DL singles in the #405 range the other day, and it only takes a few sets to get to work weight. If someone can DL #405, they are not adding #10 each set to warmup.
