Glossary

Forty plus terms used in the studies, the atlas and the mat, defined in plain words.

42 terms, in the order a reader would find them. Where a term names something this app does not show, the entry says so; the what this app is not page explains why.

Base
A position from which you can resist being moved. Standing base, seated base, combat base and hands-and-knees are the four this app rehearses.
Back control
Holding the other person from behind with the chest on their back, usually with both feet hooked inside their thighs.
Breakfall
A way of landing that spreads the impact: a rounded back, a tucked chin and an arm slapping the mat. The back breakfall is a study here.
Bridge
Driving the hips up off the mat through the heels, with the upper back and head staying down. Also called an upa when it turns a person over.
Butterfly guard
A seated guard with the feet hooked inside the other person's thighs. Not shown in this app.
Chain
Two or more movements in the order they happen in a match, rehearsed as one line. The Chains group of studies.
Closed guard
Guard with the legs wrapped and the ankles crossed around the other person's waist.
Combat base
Kneeling on one knee with the other foot posted forward and the rear toes tucked. A study here.
Escape
Any movement that leaves an inferior position. The hip escape and the reverse hip escape are the two rehearsed here.
Frame
A bone structure, usually a forearm or a shin, placed between you and the other person to hold distance so the hips can move.
Gi
The jacket, trousers and belt worn in gi classes. A rule set may call it a kimono.
Granby
A rolling inversion across the shoulders. Not a study here; the shoulder-stand rock is the preparation for it.
Guard
Any position on the bottom where your legs are between you and the other person.
Guard pass
Getting past the legs to side control, knee on belly or mount. Defined by the legs being passed, so not shown by a solo model.
Guard retention
Keeping the legs between you and a passer. The hip swivel study is the hip pattern only.
Half guard
Guard with one of the other person's legs trapped between yours.
Heel hook
A leg lock that twists the knee through the heel. Illegal in many rule sets and not shown here.
Hip escape
Posting a hand or an elbow, turning onto a shoulder and pushing the hips away from the other person. Also called a shrimp.
Hip heist
From seated, driving the hips up over a posted hand and landing on the knees facing the post.
Hooks
The feet placed inside the other person's thighs from the back. A rule set usually requires them for back control to score.
Inversion
Any position where the hips are above the shoulders. The shoulder-stand rock is the first shape.
Knee on belly
Top position with one knee across the other person's abdomen and the other foot posted.
Knee shield
A half guard frame made with the shin across the other person's chest or hip.
Mount
Sitting astride the other person's hips or chest with both knees on the mat.
No-gi

The alignment of the spine and the head, usually meaning upright with the head up, inside someone's guard or in a base.
Reverse hip escape
Both feet push so the hips slide along the mat toward the head. A study here.
