Long-time lurker, picked up lots of valuable info here. My thanks to everybody. I managed two PRs today, 1x5 at 294, and then 1x1 at 304, so woohoo for me. My question is this: I lift at home and only have the 25 pound plates, so the bar is I suppose 2 or more inches lower to start. Is that significantly harder than with the 45 plate diameter? In other words, would I have hit 300 sooner? I'm 6'-1" tall.
