why does my left arm tremble when using light weights?
I have notice that while using light weights (like 2.5lbs) while doing either biceps curls or other arm exercises, my left arm will start trembling when bringing my arm down. I am not for sure why this is happening, but there are no problems with my right arm - just the left. Anyone else experience this? Serious replies only. Thanks for taking the time to answer my question! :)
