巴西柔术起初是一种扭斗的武术，它的技术和策略都基于对地面打斗的深入研究。柔术练习者，擅长将对手拖向地面，然后在地面上获得控制的姿势。一旦形成控制姿势，柔术练习者可以使用关节技、绞技或击打技术等多种攻击手段，将对手制服。视频为衣领绞(膝顶胃)教学。

中文大意：
此前我们讲过一次防守位的衣领绞，今天我们要讲的是膝顶胃位置的衣领绞。
从侧控位开始，右膝盖抬起顶住对手的胃部，左腿弓步站起。(如果左腿不站起，那么身体的重量就压在地板上了，右膝盖并没有给对手造成压力)右手抓住对手的胯部，左手抓对手的肩膀，控制住对手。
左手拉开对手的衣领，右手伸过去抓住，四指在内，大拇指在外。左手交叉过去，紧贴对手的脖子抓对手的衣领。(如果对手的衣领是开着的，左手可以伸进去，但是一般情况下不是开着的，另外注意左手不要抓对手外侧肩膀，一定要抓紧贴着脖子的肩膀)
接下来，右手肘朝向自己的胸腔，头部下沉去贴近对手的脸，向下施加力量，直到对手拍垫认输。
视频英文原文：
Knee in the stomach, knee in the belly I call it sometimes. This is a control position here and here. OK. To get to this position, I start from the side mount. I hop up. My leg is up. This is not a knee in the belly. Right here, the floor is carrying my weight. I want my opponent to carry my weight so I’m going to be up on my foot there. Here and here.
Now we’re going to go for a choke in the knee and the stomach. Here, open his collar. Four fingers in, one thumb out. Here my other hand goes over. And notice I’m grabbing the shoulder. My hand is tight against his neck. I’m not just grabbing here. That’s a lot of space. Right here. If his gig was open I’d put one thumb in and do it like so, but a lot of time it’s tight.
You could just grab the fabric on the shoulder right by the neck, right by the throat here. I’m going to pull my elbows towards my rib cage as I put my head down by his head. Hands together. Do not do this. That’s wrong. Elbows must go towards my rib cage. And I put my weight down. And that’s your choke from the knee and the belly.
