Leg Locks for Beginners: What You Need to Know Before You Start
Leg locks are submissions that target the knee, ankle, and hip joints of your opponent's lower body. If you're new to BJJ, you're going to run into them whether you're ready or not, so you might as well understand what they are, which ones are safe to drill early, and how to not get your training partners hurt in the process.
Key Takeaways
- The straight ankle lock (aka "the Americana for the ankle") is the right starting point for beginners — it's low-risk and high-percentage
- Heel hooks are effective but genuinely dangerous; most gyms restrict them to intermediate and above for good reason
- Leg lock defense (footlock awareness, not getting stuck in bad positions) matters as much as offense
- Learning leg locks early actually improves your guard passing and guard retention because you understand what you're exposing
- Drilling with a partner under supervision beats watching YouTube and winging it in rolling
Why Beginners Usually Avoid Leg Locks (And Why That's Changing)
For a long time, leg locks were treated like the dark arts of BJJ. Traditional gi schools, especially ones following older IBJJF rulesets, kept them off-limits for white and blue belts. The IBJJF ruleset still restricts reaping and heel hooks at most belt levels in gi competition, and that shaped how a lot of gyms taught the sport.
The no-gi side of grappling, pushed hard by competitors and coaches like those in the ADCC circuit, brought leg locks back into the mainstream over the last decade. Now you've got white belts watching Gordon Ryan highlight reels and immediately trying to jump to heel hooks their first month of training. That's a problem.
Here's the honest breakdown: leg locks are part of complete grappling. You should learn them. But there's an order to this that matters, and skipping steps gets people injured.
The Three Leg Locks You'll Actually Encounter as a Beginner
Straight Ankle Lock
This is where you start. Period. The straight ankle lock (also called a straight footlock or ankle lock) attacks the Achilles tendon and the ankle joint. You control the leg by trapping the foot under your armpit, applying pressure from the hip flexion or rotation.
It's the most fundamental leg lock entry and it's legal at white belt in most competition rulesets. More importantly, it's slow enough that your training partners have time to tap before anything bad happens, and it teaches you the foundational mechanics that carry over to more advanced entries.
The setup from the outside heel hook position is also where you'll learn the 50/50 and ashi garami positions, which are the building blocks for everything else. So even if you're not going for heel hooks, learning ankle locks properly means you're already building the right vocabulary.
Kneebar
The kneebar hyperextends the knee by using your body as a lever against the joint. It's more dangerous than an ankle lock because the knee can pop faster than the ankle, which means training partners need to tap earlier and more reliably.
Kneebars are a good intermediate step. They show up a lot when you're passing guard or when someone is turtling. But beginners shouldn't be the ones initiating kneebars in live rolling until they've got a feel for how quickly the submission comes on. In gi competition, kneebars are generally restricted to brown and black belt under IBJJF rules.
Heel Hook (Inside and Outside)
Let's be straight about this one: heel hooks are the most powerful and most dangerous leg locks in grappling. The inside heel hook in particular can injure the knee without giving your training partner much warning. We're talking ACL, MCL, and meniscus damage, often simultaneously.
That's not a scare tactic. That's anatomy. The knee doesn't have a great warning system when rotational force gets applied to it the wrong way. Your training partner might feel nothing until it's already too late.
If your gym allows heel hooks in rolling, that's their call. But as a beginner, you've got no business going for them in live rolling until you've drilled them extensively, understand the mechanics cold, and know how to control the submission at every stage. Watch what's happening at a school like BJJ Heroes covers in their techniques section to see how systematically the best competitors approach this.
A Story: Carlos Learns the Hard Way
Carlos trained at a spot in Bensonhurst for about eight months before he started coming to privates. Good guy, athletic, picked up concepts fast. The problem was he'd been watching a ton of no-gi footage and started going for inside heel hooks in rolling without drilling them properly first.
He didn't hurt anyone badly, but he did tweak his own knee because he was in a scramble and got caught in a position he didn't understand. He couldn't roll for three weeks. When he came back, we spent the first two sessions just on outside ashi garami and straight ankle locks, drilling the controls before touching heel hooks at all. By session four, he had better heel hook mechanics than guys who'd been training twice as long, because he understood the position instead of just grabbing the heel and yanking.
The lesson isn't that heel hooks are too dangerous to learn. It's that you can't rush the foundation.
Leg Lock Defense Is Just as Important as Offense
Here's something a lot of beginners miss: you're going to get your legs attacked before you attack anyone else's. Knowing how to defend is actually the more urgent skill.
The basics of leg lock defense come down to a few things:
Heel position. Your heel needs to be tucked or protected. If someone has your leg and your heel is exposed, you're in danger. One of the first things I teach beginners is heel awareness: where is your heel relative to your opponent's hips and hands at all times.
Knee alignment. When someone's attacking your leg, you want your knee and toes pointing the same direction. As soon as your leg gets twisted so the knee and toes are pointing different ways, you're in trouble. Don't let that happen.
Don't panic and yank your leg out. This is counterintuitive but important. Yanking your leg out of a leg lock attempt, especially a heel hook, can cause just as much damage as the submission itself. Learn to create space and recover your leg systematically, not frantically.
Spend time getting your legs attacked in drilling specifically so you understand what it feels like and develop calm responses. That's worth more than any offensive technique at this stage.
If you want to work this in a focused session, booking a private lesson is the fastest way to get hands-on reps with someone walking you through the defense in real time.
What Positions You Need to Know First
You can't do leg locks without being in a leg lock position. Before drilling submissions, learn these two fundamental positions:
Outside ashi garami. This is your base position for straight ankle locks and outside heel hooks. You're sitting with your legs controlling one of your opponent's legs, your outside leg hooked over the top of their thigh, inside leg on the mat. This is the safest starting point. It's stable, it's controllable, and it's where most beginner leg lock work happens.
Single leg X (SLX). Also called "honey badger" in some gyms. You're on your back with both hooks controlling your opponent's leg, hips elevated. This position loads up the knee and sets up more powerful sweeps and submissions. It's also a great sweep position if the submission doesn't come.
Learn to get into these positions from bottom guard scenarios. A common entry is when your opponent stands up to pass your guard and you shift to attack the leg instead of recovering guard. That's a real, practical situation you'll see in every rolling session.
A Story: What Marcus Figured Out in Two Sessions
Marcus came to me about a year into his training, solid blue belt candidate, good top game but constantly getting swept and hit with leg locks from the bottom. He'd been drilling guard passing without ever thinking about what legs could do to him from below.
We spent the first session entirely on outside ashi garami from his opponent's perspective: how to enter it, what it feels like, and what the danger zones are. Second session, we did straight ankle lock offense from that position for forty-five minutes.
By the end of that second session, Marcus understood why people were catching him. He was walking into leg lock entries every time he tried to knee-slice because his weight distribution was wrong. One small adjustment to his base when passing fixed his guard passing and made him almost immune to the most common entries he'd been falling for. That's the thing about learning leg locks: it makes you a better top player, not just a better leg locker.
When to Start Drilling Leg Locks (Honest Answer)
There's no universal rule, but here's a reasonable framework based on 7 years of training and competing:
Month 1-3 (brand new): Don't worry about leg locks offensively. Focus on surviving, basic positions, and fundamental submissions (armbar, rear naked choke, triangle). Learn what ashi garami looks like so you can recognize when you're in danger.
Month 3-6: Start drilling straight ankle locks specifically. Learn outside ashi garami. Practice the entry from standing guard pass attempts. Get your training partners to attack your legs so you develop defense.
Month 6-12: Add kneebars in drilling. If your gym allows it and you've got solid fundamentals, start exploring heel hooks in controlled drilling with a trusted partner, not in random rolling.
1 year plus: Heel hooks in rolling, with discretion and a gym that trains them properly. Not every gym does. If your gym doesn't, respect that.
The IBJJF's age and experience guidelines exist because of injury data, not arbitrary conservatism. Check their current rulebook before entering any competition so you know what's legal at your belt level.
Research published in sports medicine journals consistently shows that knee injuries from heel hooks specifically account for a disproportionate share of serious grappling injuries compared to other submissions. That's not an argument to never learn them. It's an argument to learn them right.
Drilling Leg Locks in Brooklyn: What a Good Session Looks Like
Here's what focused leg lock drilling actually looks like when it's done well. You're not just attacking and defending randomly. You're building a specific chain.
Start with the position: get into outside ashi garami from a standing opponent. Drill that entry twenty times each side, slow. Then drill the ankle lock finish from there, focusing on the mechanical squeeze, not muscling it. Then add a simple sweep option (the standard plan B if they pull their leg out) so you're not one-dimensional.
That's one hour. You walk out understanding a position, one submission, and one sweep. That's more useful than two hours of live rolling where leg locks happen randomly and you don't know why.
If you're training at a group class-heavy gym, you know you're not getting this kind of structured drilling in a regular class. That's exactly why grapplers in Brooklyn looking to actually understand leg locks come to private lessons. You get the drill time without the chaos.
For context on what private instruction costs and what you get, check out the pricing page. Bringing a training partner cuts the cost in half and means you've got a dedicated drilling partner right there.

A Common Mistake: Treating Leg Locks Like Shortcuts
There's a mindset that shows up sometimes with newer grapplers, especially guys who've watched a lot of leg lock-heavy footage. They start thinking leg locks are a shortcut around learning the whole game. Don't tap to armbars, just go for legs. Don't learn guard, just jump to ashi.
That's backwards. The best leg lock grapplers in the world have excellent top games, excellent guard retention, and excellent takedowns. Leg locks work inside a complete game, not instead of one. Gordon Ryan doesn't just know heel hooks. He understands every phase of the match and puts opponents in positions where legs are exposed because of his overall grappling pressure.
As a beginner, your focus should be on understanding positions and transitions. Leg locks are one part of that, not the whole thing. Get your beginner fundamentals solid first. The leg locks will make more sense and be more effective when they sit inside a game that's actually working.
Start Simple and Build From There
Leg locks for beginners means one thing practically: learn the straight ankle lock, learn outside ashi garami, and learn how to defend your own legs. That's your homework for the first six months. Everything else builds on that foundation.
The worst thing you can do is skip the foundation and start muscling heel hooks in rolling. You'll either hurt someone, hurt yourself, or develop sloppy mechanics that a more experienced leg locker will exploit immediately.
If you're in Brooklyn and want to build this the right way, I work with grapplers at all levels on exactly this kind of focused technical drilling. One session is enough to cover the basics of outside ashi and the straight ankle lock properly. Book a private lesson and come ready to drill.
