Just tried that myself, and it's the same.
Unless you're shaking all over the place, I don't think it's a big deal.
Go to the weight room or gym and you'll see it happening all around you.
(i'm not a doctor though so take it with a grain of salt...)
edit - i'm a incredibly' skinny man, so it might be different for those who have serious muscle mass. (i be 150 lbs right now)
