Push press 3-3-3-3-3-3-3 reps

I started with 135lb, and worked my way up to 155. From there, I tried getting up to my 1-rep max of 175, but really struggled with that. Went down to 145, really struggled with form, and back I was, doing 3 reps at 135 again.

I really, really need to push myself further on shoulder exercises, as they are seriously out of balance.
