Normally, I use a standard 45 lb bar for benches and always use the exact same grip width. For the moment, I do 245 lbs x 5,5,5. Well, on Monday, I had to get my workout in at home with my 20 lb curling bar. I loaded up 240 lbs and my grip width was slightly different. I didnt realize it at first, but because of the legnth of the bar, it was a tad closer Im guessing. Anyways, I only got 240 lbs x 5,4. The next day, my chest was sore which is not normal for me anymore.

I was thinking I used less weight because of the change in grip width.. either focusing slightly more on my tri's or simply because of new neural adaptions.

My question is, Is there any advantage to changing my grip width slightly? Im speaking in terms of hypertrophy and getting a higher bench since Ive sort of hit a stand still.
