Hi, this is Madison Chase, your trainer to the stars and the star in you. So, today we're going to talk about standing bent-knee crunches. So, we're going to do three different crunches. So, the first crunch that we're going to do, you're going to take your same knee and bring it to your same collarbone -- so, your right knee or your left knee. You could alternate your right knee, right collarbone. Now, we're going to do almost like a crab position. So, you're going to think about taking your elbow to your knee, right and left side. Now, we're going to do across. So, you're going to take your opposite elbow to your opposite knee. Okay, so, you could actually do this three different ways. So, you could actually alternate your right and your left, or you could just do standing one side. So, when you're doing repetitive repetitions, actually a little bit harder. Alternating is actually a lot easier. So, we have forward, right, side, and then opposite. So, those are your three bent-leg crunches. You could either alternate -- so, if you're just starting out, I want you to do, give me eight to 10, and if you're intermediate level, I want you do to 10 to 15, and if you're advanced and you got great abs and you're trying to get better abs, I want you to do 20 to 25. I'm Madison Chase, your trainer to the stars, and the star in you. And, these are your bent standing leg crunches.
