Does this ever happen to you?

Say you're doing something like alternating dumbbell curls, or say u were to do a side lateral with a dumbbell in only one hand. Ur other arm feels kinda weird, like the circulation is cut off, and ur veins pop out like mad, even though it's the other arm that's doing the work and that one should just be relaxed?

I always get an increased heart rate doing bi's. LOVE THE PUMP!!
