Bent Knee Glute Kickback
The Bent Knee Glute Kickback is an isolation exercise that targets the glutes and helps improve hip control and muscle activation.
Bent Knee Glute Kickback
From a hands-and-knees position, the Bent Knee Glute Kickback isolates the glutes by extending the hip with the knee bent. Keeping the knee at roughly 90 degrees shortens the hamstring lever arm, which forces the glutes to handle the majority of the workload. Short-duration glute activation exercises like this one enhance subsequent muscle performance and improve the brain-to-muscle connection (Cochrane et al., 2017).
The core and supporting leg work to keep your hips level and prevent rotation, while the working glute drives the thigh upward in a controlled arc. Avoid arching the lower back or swinging the leg — the goal is precise hip extension, not momentum. Loading the hip extensors through a controlled range builds both strength and movement quality (Lawrence et al., 2022).
Use this exercise in warm-ups to wake up the glutes before squats or deadlifts, or program it as focused accessory work to add volume without heavy spinal loading. It is especially useful for improving glute engagement and supporting better mechanics in all lower-body movements.

Technique and form
How to perform the Bent Knee Glute Kickback
- Position yourself on all fours with your hands directly under your shoulders and knees under your hips, keeping your back flat and core engaged. Breathe naturally and maintain a neutral spine position.
- Choose one leg to work with and bend it to a 90-degree angle, keeping your foot flexed and knee pointing down. Stabilize your position by pressing firmly through your supporting limbs.
- Engage your core muscles and squeeze your glutes as you prepare to lift the working leg. Maintain even weight distribution through your supporting hands and knee.
- Exhale as you push your bent leg up and back until your thigh is parallel to the floor and your foot is pointing toward the ceiling. Keep your hips square to the ground to isolate the glute muscles.
- Hold the contracted position at the top for 1-2 seconds, focusing on the squeeze in your glute muscles. Maintain a stable torso without rotating your hips or arching your lower back.
- Inhale as you slowly lower your leg back to the starting position without touching your knee to the ground. Control the descent to maintain tension in the working muscles.
- Repeat the movement for the prescribed number of repetitions before switching to the other leg. Maintain consistent breathing throughout each repetition.
- To increase intensity, you can add ankle weights or resistance bands just above the knee of the working leg. Ensure proper form is maintained when adding resistance.
Important information
- Keep your abdominals engaged throughout the entire exercise to protect your lower back from excessive arching.
- Focus on using your glute muscles to power the movement, not your lower back or hamstrings.
- Maintain a neutral neck position by gazing at a spot on the floor about a foot in front of you rather than looking up or down.
- If you experience any knee discomfort, try placing a folded mat under your supporting knee for additional cushioning.

Benefits of the Bent Knee Glute Kickback
Muscles Worked: Bent Knee Glute Kickback
The Bent Knee Glute Kickback is an isolation exercise that focuses your effort on the glute muscles. Here's a breakdown of every muscle involved.
Primary muscles
Glutes — Your glute muscles generate hip power and keep your pelvis stable. These are the main muscle doing the heavy lifting during the Bent Knee Glute Kickback.
Secondary muscles
Hamstrings — Your back of your thighs (hamstrings) control the lowering phase and assist the hips. While not the main focus, these muscles play an important supporting role.
The Bent Knee Glute Kickback primarily works 1 muscle with 1 supporting muscle assisting the movement.
Risk Areas
FAQ - Bent Knee Glute Kickback
The Bent Knee Glute Kickback primarily targets the gluteus maximus (main glute muscle) with secondary activation in the hamstrings. The bent knee position specifically increases glute isolation by reducing hamstring involvement compared to straight-leg variations.
Stand facing the cable machine with the ankle attachment secured, maintain a slight bend in your supporting leg, and keep your core engaged throughout the movement. Focus on driving the movement from your glutes rather than your lower back, and avoid arching or rounding your spine.
Add resistance using ankle weights, cable machines, or resistance bands for progressive overload. You can also increase time under tension by incorporating pulse reps at the top of the movement or slowing down the eccentric (lowering) phase of each repetition.
The Bent Knee Glute Kickback is generally safer for those with lower back issues compared to straight-leg variations, as it reduces lumbar stress. However, proper form is crucial—maintain a neutral spine, engage your core, and avoid overextending at the top of the movement to protect your lower back.
Include this exercise 2-3 times weekly for optimal glute development, typically programming 3-4 sets of 12-15 repetitions per side. You can use it as part of a dedicated lower body session or as an activation exercise before compound movements like squats and deadlifts.
