Coming to the end of my grip strength

[lyorn]

I'm doing the NRoLfW program, and there are some leg exercises there that require holding a dumbbell in each hand. With today's weight I found that I have difficulties holding the dumbbells (not helped by the grips on the dumbbells being made for larger hands than mine), because my grip strength is not up to my leg strength. It has increased, but not as much as needed.

Anyone has had that happen, too? Any tips?
