Don't feel bad man, you're rowing heavier than I am "atm"
.
Right now I'm comfortable pulling the 115's in good form for around 5-6 reps. I pulled a 140 once, but I considered the rep kinda sucky as I had to pull back and up too much to get the weight up.
I've probably got you on weight by 20lbs so your rowing is going very nicely imo.
It's funny because you'll probably look back at that post a year from now when you can rep a 150db for 10+ reps and laugh.
