Let’s suppose I’m doing a set of ‘6 DB snatches’. Would that be 6 alternating with each arm, or 6 snatches with each arm (or 12 altogether).
With things like rows or lunges, sure, you do each arm. But the DB snatch doesn’t really have the upper body as a prime-mover, the limiting factor is your lower body’s ability to explode.
I just like knowing these things so I can write down the right number of reps.
