Panda,
I posted on your other thread as well. Aerobics won't contribute to twitching, but lifting weights may, but, -- and that's a big important "but" in there, -- that is a HEALTHY sign, and your body is supposed to do it.
Honestly, if you felt "nothing," my personal opinion is that you weren't doing much of anything in the gym with regards to strength training, but rather just doing the treadmill.
If you're working at an optimal level, your body is supposed to have sensations in your muscles. It's a good things! :)
