Jessica -- Baby's First Workout

She's got a growing baby inside her uterus, but that won't keep Jessica Alba from working out!

TMZ caught the ever-silent, never-smiling Alba leaving Emerson Hall Fitness, a "Zen Fitness Training" workout zone in West Hollywood yesterday afternoon.

Alba wasn't looking too Zen on her way out though -- showing off her somewhat growing belly but hiding her moneymaker of a face as she took off.
