Americana in BJJ: Keylock From Mount and Side Control

Where the americana lives

Two positions feed it: mount, when they push your chest or throw an elbow wide, and side control, when their far arm reaches for your neck or your hip. The condition is always the same: elbow bent near ninety degrees, the back of the hand on the mat, fingers pointing toward their own head. If the arm straightens or changes direction, an armbar or kimura may become an option, but each needs its own control and alignment. Learn to read the arm before you touch it. Under the IBJJF rulebook the americana is legal at every adult belt; kids' divisions have their own table.

The mechanics: control the wrist and upper arm

In the conventional figure-four, one hand controls the wrist while the other arm passes under the upper arm and grips your own wrist. The bent arm and your body position limit how freely the shoulder can follow. The wrist stays near the mat as a small, controlled elbow lift creates the lock.

A common cue is to slide the back of the hand toward the opponent's hip before lifting the elbow. Treat it as an alignment cue, not a demand for a fixed range: shoulders differ. Keep the movement gradual and release at the tap. Practice one version consistently before combining details from different demonstrations.

From mount: keep a base

Use your hands without giving away your balance. As you isolate the arm, keep a stable base and respond to the opponent's bridge and hip movement. Leaning far over the wrist can make the grip feel stronger while making mount easier to reverse.

First practice isolating the arm while your partner gently tries to recover an elbow to the ribs. Then add the figure-four without finishing. If mount is lost during those steps, more pressure on the shoulder is solving the wrong problem.

From side control

From side control, attack the far arm. The moment their hand comes up to push your face or your hip, catch the wrist and pin it to the mat, then thread the other arm underneath for the figure-four. Keep your chest on their chest; the beginner error is chasing the arm while the hips float away and the guard comes back. If they straighten the arm, switch to a straight armlock or step over the head toward north-south. If they pull the elbow to the ribs, keep the pin and go back to pressure.

Americana vs kimura

Both are figure-four shoulder locks; they rotate in opposite directions. The americana bends the arm upward, hand toward the head, and rotates the shoulder outward. The kimura bends the arm downward, hand behind the back, and rotates the shoulder inward. Position decides which you get. The americana favors mount and side control, where the mat pins the arm and gravity helps. The kimura favors the guard, north-south and the turtle, where your whole body is the lever, and it doubles as a control system for sweeps and back takes. Chase the arm, not the name.

Why the lock stalls

The wrist may drift out of position, the elbow may return to the ribs, or the opponent may turn the whole body with the pressure. Your pin may be loose enough for guard recovery. Check these possibilities before increasing force.

Begin a drill with the figure-four connected but no finishing pressure. The defender improves the arm position while the attacker maintains control. That makes lost alignment visible, and a coach can correct a specific detail. Gripping style has variations; a wrapped thumb alone does not explain every failed Americana.

Early defense and the next decision

Before the figure-four settles, keeping the elbow connected to your torso and recovering a useful frame can make the attack harder to establish. Once isolated, the right movement depends on the pin and direction of pressure. Do not wrench the shoulder through a secured lock: tap and restart.

For the attacker, a defended Americana may lead to another attack or a better pin. For the defender, freeing the arm is the start of the escape: you still need to recover guard or another useful position. Ask where control first disappears rather than simply how to squeeze harder.

Choose one position from this guide to recognize at your next class. With an active BORETS LAB membership, you can study related lessons and ask a coach privately under the lesson or in the school messenger. Explain the starting position and the detail you want to clarify.
