Someone has really learned a lesson

x1337xNoobx:
What are your stats ?
BW, height, squat, bench, ohp, deadlift, ... ?
Why can't you do inverted rows ? Lack of strength ? Lack of equipment ?
BTW 22Alpha is correct.
If you can not do inverted rows due to lack of strength, focus more on them.
Do them with your feet on the floor, knees bend at 90 degrees.
Do SLOOOOOW negatives only for some sessions if needed.
Since your gym does not have a barbell, how are you doing the program then ? Only using dumbbells ? Not ideal so yes, change ASAP if possible.
But this means you can do dumbbell rows, right ?
As a side note:
power clean works mostly in the vertical plane. IR/BBRow work in the horizontal plane. So you would be making a wrong change.
I am not saying further down the line you can not do powercleans but not now. Certainly not if you can not do IRs yet.
Barbell/Dumbbell rows are the only allowed substitution for now.
EDIT:
looks like this thread is more or less in sync with another thread started by x1337xNoobx (and it is indicated there IRs are not possible due to strength reasons)
Therefor I close this one, discussion can continue in the other thread:
