I seem to be a bit confused. It seems like my first sets when I do bench go up every week, but my last sets with more weight and less reps haven't gone up recently. For example, 3 weeks ago my workout called for my first set 185 x5, which I did and the 5th rep was all I could do-after that another set of 185 x5. Next week 190 x 5 for 2 sets, again the 5th rep was all I could do. Today, a week later I did 195 x 5, but for all 3 weeks my second or third set called for 215 x 2(185 week), 215 x2 again(190 week) and today 215 x3. Each week I could only do 215 one time.
What I don't get is why wouldn't I be able to do 215 at least twice by now considering my stength has progressed in the last 3 weeks by 10lbs for my first set? Should my stength for heavier sets increase accordinly with my stength for lighter sets?
