Guard retention in BJJ: hip movement, frames and inversion against the pass. IBJJF guard definition, the hand-or-foot-on-face foul, data on knee and shoulder.
Guard retention (keeping your guard) means preventing your partner's pass: with hip movement, frames and inversion. That is how the DOMISPORTS skill catalogue describes it; it lists inversion and Granby roll (BJJ) as aliases and inversion, Granby roll and frames as variants. How you move the hips, where a frame stands and when an inversion makes sense is shown by your coach. It depends on the school, and this text deliberately explains frame, rules and safety, not the technique in detail.
The honest answer: guard retention is safety-critical, above all the inversion in which you turn upside down. A text cannot show you how to protect neck and shoulder in the process; that belongs under a coach's supervision. The catalogue names shrimp as a prerequisite, the hip movement to the side. How long you need for reliable guard retention cannot be stated; there is no study on it.
The frame is in the rulebook. The IBJJF rulebook (version 6.1, 2024) defines guard as the use of one or more legs to stop the opponent from reaching side control or north-south [1]. If the guard is passed and the opponent holds side control or north-south for 3 seconds, he gets 3 points [1]. Guard retention is therefore nothing other than the attempt to prevent exactly that. If the passer reaches half guard control from the guard and does not consolidate the pass, he still gets an advantage point [1]. The earlier you bring your legs back between yourself and him, the less of that remains.
The order follows the catalogue's description: hip movement, frames, inversion. The inversion comes last and only with your coach's consent.
You move the hips to create distance between you and your partner. Milestone: you move ten times per side without your partner landing flat on you.
You set arms and legs as a frame between you, without touching face, belt or the lapel behind the neck [1]. Milestone: you hold the frames for 30 seconds against a slowly working partner.
You bring your legs back between you and your partner as the guard definition requires [1]. Milestone: you recover the guard in five of ten attempts before your partner holds side control.
You practise the inversion only after your coach's release and on a mat with enough space. Milestone: your coach confirms that you can perform the movement slowly and with control.
You start with pass attempts from different situations. Milestone: you prevent the pass in three of ten two-minute rounds against light resistance.
This skill is safety-critical. The knee is the most affected region in BJJ: 27.1% of injuries in a survey of 1,140 athletes, above all meniscus, anterior cruciate ligament and medial collateral ligament [2]. In a survey of 198 athletes, knee and shoulder stood out among advanced athletes and guard players [3]. A Dutch survey named knees (25%) and shoulders (13%) in front and found 79% of training injuries in sparring [4]. These sources give no data on inversion and Granby roll. As an inference: never turn upside down if your coach has not released it, do not press the neck against the mat when rolling, and tell your partner beforehand what you intend. The concrete technique of neck protection is shown by your coach. This guide explains and motivates; it does not replace supervised training.
Turn guard retention into a game: your partner starts in a situation from which he wants to pass, and you have two minutes to bring the legs back between you. Note in which situation it failed: hips, frame or reaction. Ask your coach which of the three parts he would improve first in you. That is practice, not a study, but it directs your attention to the place where you lose.
Preventing the pass through hip movement, frames and inversion. That is how the DOMISPORTS skill catalogue describes it.
As the use of one or more legs to stop the opponent from reaching side control or north-south [1].
No. A hand or foot on the opponent's face is a serious foul under the IBJJF rulebook [1].
The skill catalogue rates it as safety-critical. The studies read give no figures for this movement. Learn it only with a coach.
