When doing alternating dumbbell exercises where you only work one side at a time, holding only one dumbbell, eg Dumbbell Rows or Kroc Rows, which side should I start with?
I've taken a look at some videos and most people start with their right side. This confuses me. Most people are right handed and hence I assume that the right side is their stronger side. 

I wonder if it makes sense to begin with the weaker side so that I am not too exhausted when switching to the other side.
So should I start with the weaker or stronger side?
