 Okay, so we're going to talk about a lunging, split squatting, walking lunge variation that people will mess up really easily and this is when I'm driving my body weight back up from the ground and I kind of lead with my butt and I stick my butt out a little bit more, kind of like Daffy Duck, the old Looney Tunes cartoon guy. So let's see what it looks like. So I'm going to show it in a reverse lunge position so I take a step back and I might even have an okay position, but what I'm going to say is that you're probably going to have a slightly arched low back position when you're coming down like this. And then as I start to come up, I want to look for how I'm driving myself back up. Now ideally, I'm pushing my entire body away. I'm kind of keeping this same shape up here in my upper half and I'm just letting everything rise together and then come forward so that I'm on my front leg. But what you're going to find is happening is you're going to push this butt up first and you're going to increase the arch in your back. So instead of keeping this midsection, your spine area really stiff like a board, what you're doing instead is you're leading with your butt and then trying to finish probably a little bit arched back at the top. Now I'm exaggerating some of these positions. Probably not going to mess it up like I'm showing you, but I'm trying to make it easier to see. So let's just do it full speed. Okay, so this is the bad way. You notice my butt comes up first and I notice that I push more through the ball of my foot. Okay, I feel more of my toe pushing in the ground. Feel less of my heel, less of my hamstring, a little less of my glutes, and I feel more of my general front of knee and front of hip. Okay, so those are things that I don't want to feel. So what's the fix? Well, you just have to learn how to get this tuck position first and foremost, see if you can set that up at the top. I like to say, pretend you're wearing a belt and you're trying to pull your belt buckle up ever so slightly and then the secret will be, this is the hard part, to maintain it on the way back up. I like to think about leading with that belt buckle up and then it's going to feel like you're really hunched over, but it's actually going to look pretty straight if you see it in a video. Okay, so I lead the belt buckle up as I stand back up. Okay, and it should look something more like this. Okay, hopefully that makes sense. So again, just to review what's happening is the low back is arching at the bottom. What I need is to restore a little tuck and keep it as I drive my body weight back up on these lunges.
