The Kang squat is a barbell compound movement that links a good morning into a full squat and back out, training the glutes, hamstrings and lower back through a hinge that flows into a squat. Named after weightlifter Shin Kang, it starts with a bar on the back and a stiff-leg hinge to parallel, then drops the hips into a full squat, then reverses: back up to the hinge, then stand. The sequence teaches you to hold a rigid back while shifting between hip-dominant and knee-dominant positions. Coaches program it light as a warm-up drill or posterior chain accessory.
What Muscles Does the Kang Squat Work?
- Primary: Gluteus maximus, hamstrings (biceps femoris, semitendinosus, semimembranosus)
- Secondary: Erector spinae (lower back), quadriceps, adductor magnus
- Tertiary: Rectus abdominis and obliques (bracing), upper trapezius, rhomboids
How Do You Set Up for the Kang Squat?
Set the bar in a rack at upper chest height with a light load. Step under it, pull it onto your upper traps as for a high-bar back squat, squeeze your shoulder blades together and grip just outside shoulder width. Stand up, step back, and set your feet shoulder width apart with your toes turned out slightly. Brace your trunk, soften your knees and fix your eyes on the floor a few metres ahead.
How Do You Perform the Kang Squat?
- Push your hips back and hinge forward with nearly straight knees until your torso is close to parallel with the floor, as in a good morning.
- Bend your knees and drop your hips straight down from the hinge until you reach a full squat, with your torso rising to a normal squat angle.
- Sit in the bottom of the squat for a moment, thighs below parallel and the bar still over the middle of your feet.
- Lift your hips back up while keeping your chest down, straightening the knees until you return to the parallel good-morning position.
- Drive your hips forward and raise your torso to standing with a flat back.
- Stand tall and rebrace with your knees soft before starting the next hinge.
What Are the Key Form Cues?
- Hips back, then hips down: Feel the hamstrings load fully in the hinge before you allow the knees to bend.
- Keep the bar over your midfoot: Track the bar path as a straight vertical line through both transitions.
- Hold a long, rigid spine from tailbone to skull throughout, especially in the change from hinge to squat.
- Reach your knees forward and out as you drop into the squat, so the hips have room to sink between your heels.
- On the way up, imagine leaving your chest at parallel while the hips climb behind you.
What Are the Most Common Mistakes?
- Loading the bar like a squat: The hinge position carries a long lever, so a squat weight turns the movement into a rounded lift; most lifters should stay well under half their squat load.
- Rounding the lower back in the hinge: Flexing the lumbar spine with the bar far in front loads the discs under shear, so stop the hinge where your back stays flat.
- Standing up before reaching the squat: Raising the chest and then squatting breaks the movement into two exercises, so keep the torso angle until the knees bend.
- Skipping the return hinge: Standing straight out of the squat removes the second hamstring loading, so lift the hips first and the chest last.
- Rising onto the toes in the squat: Shifting forward drags the bar ahead of the feet, so keep your heels down.
What Are the Best Kang Squat Variations?
- Bodyweight Kang squat: Hands behind the head, no bar, for learning the two transitions without load.
- Goblet Kang squat: Hold a kettlebell at the chest so the front load helps keep the torso upright in the squat.
- Pause Kang squat: Hold each position for two seconds to expose where you lose spinal tension.
- Single-leg good morning: Perform only the hinge phase on one leg for a unilateral posterior chain version.
- Safety bar Kang squat: Use a bar with padded handles in a squat rack to unload the wrists and shoulders.
How Do You Progress the Kang Squat?
- Add 5 to 10 pounds to the bar once you finish every set with a flat back at the bottom of the hinge.
- Build from 5 reps up to 8 per set before adding load.
- Add a fourth set once three sets of 8 are clean.
- Add a two-second pause in the hinge and in the squat bottom, or slow each phase to three seconds.
How Should You Program the Kang Squat?
Use the Kang squat either as a loaded warm-up drill right before back squats or as a posterior chain accessory after them. Train it one to two times per week for 3 to 4 sets of 5 to 8 reps, resting 90 to 120 seconds between sets because the hinge fatigues the lower back. Pair it with a Romanian deadlift or hip thrust so the glutes and hamstrings also get work without the squat component.
