Hi, I'm Amber Nimedez with LIVESTRONG.COM, and I'm going to teach you how to whittle your waistline. So, I'm going to do a plank position here on my forearms, just really squeezing my hips together, my gluts together and engaging my abs. And then, from here, you're going to pulse step to that push up position and then I go right back down. You're going to go up and down, about ten times. And then, you're going to go onto your side, stacking your feet together. I'm going to go up on my hands this time, lift up my hips, other arm stretches up towards the ceiling and all you're going to do is move your arm over and then up. And that lengthens the side your side oblique as well as strengthening it. And then you're going to do the other side. Stacking my feet, going up onto the hands, and then, you're going to bring your arm above the head and then back up of the chest. Up. And then the last one, you're going to do a reverse plank; hands facing your feet, flex your feet, open up the chest and you're just going to lift your hips up nice and and you can relax your head back. Hold for about 30 seconds. And those are some core exercise to help whittle your waistline. I'm Amber Nimedez with LIVESTRONG.COM.
