Funny how the mind works.
I went to O-lifting class on Monday night. I was shooting for a Deadlift PR of 180lbs with 3 sets of 5 reps each.
I was working my way up to my hopeful PR weight. I mis-tallied and wound up doing 2 reps at 185 (thinking it was somehow 170) and 1 rep at 195! It was so freaking hard!
I actually told Coach Holiday, "Do you ever have a week where you're lifting something you should be able to lift, yet it feels extremely heavy for some reason?"
He said it might be diet or lack of sleep or something.
Then I recalculated my weights and I burst out laughing. OMG! I was just lifting 15 lbs more than I was planning....no wonder it was so heavy.
