It’s grip strength, holding onto the dumbbells becomes tough for me when they get heavier and the reps build up.
I also find manoeuvring the weights into position before for e.g. a press is the toughest part- the selectable dumbbells that I have are quite long and therefore unwieldy, but also wrist strength is needed to transition the weight from the rack to the press position.
