Not a bad idea, you could also drink more coffee too since the caffeine acts as a good metabolism booster as well.

So far I haven't tried breaking through another PR, after New Years I've just been focusing on increasing the amount of volume I can lift. But I've been benching 185 more consistently, at the end of December I was could only do 3 sets of 185 for 5 reps now I'm pushing 8-9 reps a set. But I'm also wary of pushing too hard since back in November I fucked up my shoulder trying to go too heavy and lifting with bad form, though I've been working on that and so far working with dumbbells doing bench has helped remove any muscle imbalances. In any case I'm lifting more now than I was in November. But I'll push for another PR lift after I can hit and maintain 10 reps a set. What's your bench at?
