Standing Abs - Bent Over Punch Exercise - part of the women's fitness video series by GeoBeats. Hi, I'm Linda with Fitness 19. I'm going to be showing you a Standing Ab exercise. You're going to be working your lower body in this, your core, your obliques, and you're also be going to be working your arms. You're going to bend over, like in a squat position, and you're going to punch out opposite hands to opposite toes. This is how it looks. You want to do that 15 to 20 times, at least 2 sets, with 15 to 20 repetitions, and that's how you do it.
