I do chest + tris once a week...I did it last week (monday) but that was the only day I worked out. Had knee surgery so I was stuck at home the whole week Anyways, at the gym today, I did BB 155x10, 165x8, 165x6. Last week when I did it I could only get about 4 or 6 on the last two sets. The week before, I got 4 on the 165 sets. Explanation for this? Is it possible that the week "off" from everything else let my muscles recover?
