When I started in November of 2012, I could BARELY push up 95lbs on the bench. I wouldn't say that was max, but pretty damn close. As of today, February 26, 2013, my max is about 180lbs. I feel like I could probably do 5-10lbs more if I did it earlier in my routine, but that hasn't happened. My WORKING sets are from 140-160 usually.
I avoided doing these at the beginning to avoid injury due to bad form or weak core muscles. But when I did try, I had a hard time lifting 115lbs. I still haven't tried a MAX because again I don't want to hurt myself, but I am doing working sets of 8-10 reps at 205lbs.
I will try and work some more max reps out this week and compare to my first few weeks.
