at the end of tonight's lifties, the bar was lying there with a 35 on each side. for ****s and giggles, i alternated one-arm deadlift singles from right to left, no rest in between, for about 40 total reps. it wasn't really taxing, as it was only one rep per side. my grip was about the only thing tired at the end.

my question is -- what benefits does work like this usually provide, other than humoring the ****s and/or giggles.
