In 15 BJJ Drills you should do EVERYDAY | Cobrinha BJJ, the channel Cobrinha Brazilian Jiu-Jitsu & Fitness shares a silent, labeled demonstration of solo drills. The video was uploaded March 30, 2020, and is released under a Creative Commons Attribution (CC BY) license, which allows reuse with credit to the original channel.
The official YouTube description tells viewers to follow Rubens "Cobrinha" Charles Maciel. The instructor page at cobrinhabjj.com uses the same name: Rubens Charles Maciel, aka "Cobrinha." Those pages are the source for the real-name identification in this article. The video itself does not include speech, so the account below follows the title, the description, and the on-screen labels and movements that are visible in the footage.
This article does not make training promises. It does not say the drills will prevent injuries, replace class time, or guarantee a result on the mat.
A video of 15 everyday drills
The description calls the exercises "functional mobility drills that are particularly useful for grappling movements based off of those common in bjj and wrestling." It also says "minimal to no equipment is needed." Both lines belong to the video's own description. They are not claims added here.
The same description lists 15 named drills, from "Leg Circles - for Guard Retention" through a second inversion variation. What follows focuses on five of those 15, the ones with matching on-screen titles in the footage this article accompanies.
In those clips, Cobrinha works on a mat in a room with a door, a tall stack of shelves, and, in some shots, a small dog moving through the background. White labels at the bottom of the frame name each drill as he performs it.
Five guard drills, as the video labels them
The first is "Leg Circles for Guard Retention." He lies on his back and circles his legs, the movement the label is there to name.
The second is "Shrimps In Place." He stays on the mat and repeats the hip-and-shoulder shrimp in place, without traveling across the room.
The third on-screen title is longer: "Another Variation of Reverse Shrimps for Guard Retention." That wording matches item 7 on the official list. He is again on his back and sides, reversing the shrimp pattern the previous drill used.
The fourth label reads "Core Guard Retention Closed Guard Choke." It matches item 10 on the list. On the mat, he works from his back with his legs raised, in the shape the title describes. This article does not turn that label into instructions.
The fifth is "Solo Inversion Drill To Improve Your Flexibility," item 14 on the list. He inverts on the mat, the flexibility drill the video names it to be. The title is the source's. It is not a result promised by this article.
