For Coaches: Coaching the Kettlebell Swing
Updated: 4 hours ago
The first kettlebell swings I ever did were squats with a bell attached. I sat down, drove up with my quads, muscled the bell to eye level with my shoulders and wondered why my forearms were cooked after twenty reps. Nobody had told me the swing is a hip movement wearing an arm costume. I figured it out slowly, one sore morning at a time.
That gap between what the swing looks like and what it actually is explains most of the faults you'll see in class. New athletes copy the picture: they squat, they lift with their shoulders, they lean back at the top to "get it higher." The coach's job is to teach the engine underneath the picture. I'm still a newer coach sharpening my own eye, so what follows is what's helped me and my athletes so far. Take what fits your gym.

The Anatomy of a Good Rep
I teach the swing as five parts working in sequence. A problem early in the chain usually causes the symptom you see later.
The feet and the hinge
Feet a little wider than hip width, toes slightly out, weight spread across the whole foot. The hinge is the heart of the lift: hips travel back, shins stay close to vertical, the spine stays long and neutral, and the load lands in the hamstrings and glutes. If an athlete can't hinge cleanly with a dowel on their back, teach the hinge first. The bell can wait.
The trunk
The trunk is a rigid link that transfers force from the hips to the bell. At the top, the athlete should look like a standing plank: glutes squeezed, ribs down, quads tight. At the bottom, the brace holds the spine in position while the bell passes between the legs.
The lats and the bell path
On the backswing, the lats pull the upper arms into the ribs and guide the bell high between the thighs, handle above the knees. I tell athletes to "attack the zipper" with their forearms. A bell that drops low toward the floor pulls the athlete forward and turns the hinge into a stoop.
The arms
The arms are ropes with hooks on the end. They connect the body to the bell and steer it, but they don't lift it. Grip firm, elbows soft but not bent to pull, shoulders packed rather than shrugged toward the ears.
The float
After the hip snap, there's a brief moment where the bell rises on its own momentum and feels weightless. That float is the proof the hips did the work. I still remember the first time I felt it. The bell just hung there for a split second, and I realized I'd been fighting it for months. If an athlete never feels that, they're lifting with their arms.
Coach's cue: Hinge, snap, let it float.
Russian or American: Decide Before You Coach
CrossFit workouts usually call for the American swing, where the bell finishes overhead with the bottom pointing up. The Russian swing finishes around eye or chest height. Same hinge, but the overhead finish asks for good shoulder flexion and a stable trunk.
My approach in a group class is simple: everyone learns the Russian swing first, and the overhead finish is earned. If an athlete can't get their arms fully overhead without their ribs flaring and their lower back arching, the American swing is loading a position they don't own. For them, a Russian swing, or a swing to the height they can reach with a stacked trunk, keeps the stimulus without the cost. You lose a few inches of bell height and gain a lot of shoulder and back safety.
Name the standard and the scale in the same breath so nobody feels demoted for choosing eye level. I say it to the whole room, not to one person.
A Fault Table for the Floor
These are the faults I see most often, with what to look for and what to say. I try to spend my time in the fix column: one cue, then a drill if it doesn't land.
Fault | What you see | Cue | Fix |
|---|---|---|---|
Squatting the swing | Knees travel forward, shins angle, hips drop low | "Hips back, not down." | Wall hinge: heels a foot from a wall, reach the hips back to touch it |
Lifting with the arms | Shoulders shrug, no float, bell stalls at the top | "Arms are ropes." | Hike pass to a partner, then single swings with a pause at the top |
Leaning back at the top | Shoulders behind hips, lower back arches, ribs flare | "Finish tall, like a plank." | Standing plank holds with glutes and quads squeezed, then swings to chest height |
Low backswing | Bell drops toward the knees or floor, chest pitches forward | "Attack the zipper." | Swings with a towel threaded through the handle to keep the path high |
Early hinge | Hips go back while the bell is still in front of the body | "Wait for the bell." | Slow single reps: let the forearms touch the hips before hinging |
Soft lockout | Hips never fully extend, knees stay bent at the top | "Stand all the way up." | Glute bridge holds in the warm-up, then light, crisp swings |
The early hinge is sneaky because it looks like enthusiasm. The athlete dives into the hinge before the bell has returned, and the bell yanks them forward into a rounded back. Teach the timing: stand tall, let the bell fall, and hinge only when the forearms meet the hips. The lean-back gets worse as bells get heavier and athletes chase height with their spine. If you see it under fatigue, drop the finish height before you drop the load.
Teaching It in Ten Minutes
In a group setting, I teach the swing in a progression that fits inside a normal warm-up. Each step earns the next.
Dowel hinge: 2 sets of 8 slow reps, dowel touching head, upper back and tailbone.
Kettlebell deadlift: 2 sets of 6 with the bell between the feet, focusing on hips back and a tall finish.
Hike pass: hike the bell back like a football snap, then stand up tall and park it. Repeat 5 times.
Single swings: one swing, park the bell, reset. 2 sets of 5.
Continuous Russian swings: 2 sets of 10 at a light to moderate bell.
Walk the room with your eyes on the hips first, then the bell path, then the top position. Pick the biggest problem and leave the rest for next time. The hike pass is where I see the most lightbulbs. Once athletes feel the bell load their hamstrings on the way back, the snap forward starts to make sense.
On loading, a light bell with clean mechanics beats a heavy bell that turns into a squat. Many boxes use 24 kg and 16 kg as prescribed loads, but there's no shame in lighter bells, and newer athletes should start well below those numbers until the hinge is automatic.
Safety Notes Worth Saying Out Loud
Give the swing space. A bell that slips at the top of an American swing travels a long way, so spread athletes out, keep the area in front and behind them clear, and remind the class to put the bell down with a controlled hike rather than dropping it from the top.
Chalk hands on high-rep days, and tell athletes that a sweaty grip is a reason to pause, not to push through. Anyone who feels sharp pain in the lower back, rather than the normal muscular burn in the hamstrings and glutes, should stop, and see a physiotherapist or doctor if it persists.
The Detail That Changes Everything
The best swing coaches I've learned from see the hips before they see the bell. I'm still training my eye to do that, and when I watch the hinge and the lockout first, the arm faults and the lean-back mostly solve themselves. Respect the details, keep cues short, and your athletes should be swinging heavier and safer within a few weeks.
If your athletes want structured work on top of their classes, ATHLETESPHERE programming and coaching are built for that. To talk through which option fits them, or how you teach the hinge in your own sessions, get in touch with me here and we'll figure out the right next step together.
Your turn. I'm still learning as a coach too. If you run this differently in your gym, share it in the comments below. I read every one and would love to learn from you. If it was useful, tap the heart so more coaches find it.
