i did like 3 hours on empty stomach.

if i do say 1 warm up set, then 2 hard sets each for overhand and underhand rows, is that good? or, just stick with 1 variation?
3 hours are definitely overkill.
Try to plan for an hour session max.
If you perform the sets with right intensity you should gas out within an hour.
For rows pick a weight that wear you out after say 8-12 reps each set.
After 3 sets move on to other exercises.
Forget about variation for now.
Keep everything simple and enjoyable.
