Kas Glute Bridge
How to Do a Kas Glute Bridge
Sit on the floor in front of a stable bench with your upper back positioned against the bench edge.
Place a barbell, dumbbell, kettlebell, or plate securely across the hip crease and use padding if needed.
Plant the feet flat and choose a position that allows a strong glute lockout without the heels lifting.
Brace the trunk, keep the chin slightly tucked, and extend the hips until the torso and thighs are approximately level.
Pause at the top and squeeze the glutes while keeping the ribs down.
Lower the hips only a few inches, stopping as the knees begin to rock back toward the torso.
Re-extend the hips and return to the same top position without fully relaxing the glutes at the bottom.
Repeat using the same short range on every repetition.
Form Check & Technique
DO THIS (Technique Tips)
- Use a stable bench.
- Keep the chin slightly tucked.
- Keep the ribs down.
- Place load in the hip crease.
- Pause at the top.
- Lower only a few inches.
- Keep continuous glute tension.
AVOID THIS (Common Mistakes)
- Lowering All the Way to the Floor — Fix: use only the short upper range that defines the Kas bridge.
- Hyperextending the Lower Back — Fix: keep the ribs down and stop at glute-driven lockout.
- Bench Sliding — Fix: brace the bench against a stable surface.
- Load Sitting Too High on the Abdomen — Fix: center it over the hip crease.
- Using the Arms to Lift the Bar — Fix: hold the load only for stability.
- Feet Shifting During Reps — Fix: set them before the first rep and keep full-foot contact.
- Using So Much Load That the Range Changes — Fix: reduce weight until every rep stays short and controlled.
About Kas Glute Bridge
The Kas glute bridge is a short-range hip-thrust variation performed with the upper back supported on a bench and resistance across the hips. Unlike a full hip thrust, each rep lowers only a few inches from the top before the hips extend again, keeping the glutes under continuous tension through the upper range. Keep the chin tucked, ribs controlled, feet planted, and stop the descent when the knees begin to rock noticeably toward the torso.
Kas Glute Bridge Muscles Worked
The Kas glute bridge is a glute-focused hip-extension variation.
- Sweat emphasizes the short upper range and continuous glute tension, while Healthline also describes glute maximus, medius, and minimus involvement with hamstrings and core assisting.
Sets & Reps Guidance
Technique / Learning
Technique: 2–3 sets of 10–12 light reps while learning the shortened range.
Strength Focus
Heavy accessory: 3–4 sets of 6–10 reps while preserving the short range.
Muscle Growth (Hypertrophy)
Muscle growth: 3–4 sets of 10–15 reps with constant tension and a controlled top squeeze.

Kas Glute Bridge vs Hip Thrust
The major difference is range of motion.
- A hip thrust lowers through a much larger range before driving back up.
- A Kas glute bridge lowers only a few inches from the top, keeping the movement smaller and more continuous.
How Far Should You Lower?
Sweat suggests lowering only until the knees begin to rock back toward you. If the hips drop toward the floor, you have effectively turned the rep into a fuller hip thrust.
Does the Kas Glute Bridge Isolate the Glutes?
It emphasizes the glutes, but it does not make the hamstrings, quads, or core disappear. Describe it as glute-focused rather than a pure isolation exercise.
Barbell vs Dumbbell Kas Glute Bridge
A barbell supports heavier progressive loading, while a dumbbell, kettlebell, or plate is faster to set up. Sweat specifically lists these alternatives for lifters without a barbell.
Kas Bridge Bench and Bar Padding
Use a stable bench that will not slide and place the load in the hip crease. A bar pad or folded pad can improve comfort without changing the movement.
Healthline vs Sweat Definitions
Healthline describes a broader resisted glute-bridge setup and includes band tension, while Sweat describes the commonly recognized Kas bridge as a short-range hip-thrust variation. This page uses the short-range bench-supported definition because it better distinguishes the exercise from a standard bridge.
How to Program Kas Glute Bridges
Use them as a secondary glute exercise after heavier thrusts, squats, or hinges, or as a moderate-to-high-rep glute movement when you want continuous upper-range tension.
