My goal is to bench 300 by new year. I started a few months ago with 215 for 3x5, then 4x5, then 5x5. Once I was able to do 5x5 i added 5lbs and repeated 3x5,4x5,5x5 and continued on. I am now stuck at 255 and unable to complete 5x5. I can complete an ugly 3x5 under 255#. I am thinking of going back to 5/3/1 (which worked for 10 mos) but got anxious on my bench going up hence i deviated from the program in that lift. Please advise a progression to help me achieve 300#. I understand it may take longer than my original goal by new year. Thank you.
