Here’s Jessica Alba in workout mode this past weekend, and you know what that means, eh? Yup, we get a workout ourselves drooling over Alba’s sexy legs, and thighs, and curves, and booty in skin-tight workout leggings, woohoo! She’s also looking pretty damn busty as well thanks to that skimpy tanktop and sexy sports bra. So yeah, it’s an extended workout for us today. Enjoy the sizzling photos and check out the rest (over forty!) after the jump!
