My hamstrings aren't that tight, I can put my palms flat on the floor while keeping my legs straight. I just can't bend down that far whilst maintaining a straight back.
Look at this pic - in the description for the exercise it
says to keep the back straight, but this guys back is
far from straight.

This girl here, her hands are almost touching the floor
and she's still able to keep a dip in her back,
I cannot bend like that.

And look at the way this guys doing it, this is as far
as he bends down then goes back up again, is this wrong?
