The one leg kickback with bench support is a bodyweight glute isolation exercise that primarily targets the gluteus maximus, with the hamstrings working as synergists throughout the movement. Kneeling with both hands on a bench for stability, you extend one leg straight back and up to maximally contract the glute, making it an effective accessory movement for building hip strength and glute definition.
How to do the One leg kickback (with bench support)
- 1Position a flat bench in front of you and kneel on the floor, placing both hands flat on the bench at shoulder width for support.
- 2Start with your working leg — hip-width from the other knee — bent at roughly 90 degrees, foot flexed.
- 3Brace your core and keep your lower back neutral; avoid letting it arch or round before you begin.
- 4Drive the working foot straight back and upward, extending the hip fully until your thigh is roughly parallel to the floor or slightly above.
- 5Squeeze your gluteus maximus hard at the top of the movement and hold for one second.
- 6Lower the leg back to the starting position in a slow, controlled manner without letting your knee touch the floor.
- 7Complete all reps on one side before switching to the other leg.
Form tips
- Keep your hips level and squared to the bench throughout — resist the urge to rotate the pelvis upward to gain range of motion.
- Focus on driving through the heel rather than the toe; this better engages the glute and reduces hamstring dominance.
- Move through the hip, not the lower back — if you feel strain in your lumbar spine, reduce the range of motion.
- A slight bend in the knee of the working leg is fine; the goal is glute contraction, not a fully locked-out leg.
Common mistakes
- Hyperextending the lower back: Arching the lumbar spine to kick higher shifts the load off the glute and onto the spinal erectors, risking lower-back strain.
- Rotating the hip outward at the top: Letting the working hip flare up feels like a bigger range of motion but actually reduces glute activation and stresses the SI joint.
- Using momentum to swing the leg: Kicking the leg up quickly removes tension from the glute; slow, controlled reps produce far greater muscle stimulus.
- Neglecting the core brace: Without a stable core, the pelvis tilts and the lower back compensates, reducing effectiveness and increasing injury risk.
- Rushing through reps without a squeeze: Skipping the top contraction shortens time under tension — pause briefly at the top to maximize glute engagement.
Frequently asked questions
What muscles does the one leg kickback with bench support work?
The primary muscle worked is the gluteus maximus, which drives hip extension. The hamstrings act as synergists, assisting with the extension movement. Core muscles also engage isometrically to stabilize the pelvis throughout the exercise.
How many reps and sets should I do for the one leg kickback?
For glute development, 3–4 sets of 12–20 reps per leg works well. Because this is a bodyweight isolation movement, higher rep ranges with a slow tempo and a deliberate squeeze at the top tend to produce the best results.
Can I make the one leg kickback harder without adding equipment?
Yes. Slow down the eccentric (lowering) phase to 3–4 seconds, add a 2-second pause and hard squeeze at the top, or perform the movement with a resistance band looped around the working ankle and anchored under the stationary knee.
Is the bench kickback better than the donkey kickback on all fours?
Both target the same muscles. The bench-supported version raises your upper body slightly, which can feel more comfortable on the wrists and shoulders, and the elevated position may allow a slightly greater range of hip extension for some people. Choose whichever lets you maintain better form.
Why do I feel my lower back instead of my glutes during kickbacks?
This usually means you are hyperextending the lumbar spine to lift the leg higher rather than extending through the hip. Lower the range of motion, actively brace your core before each rep, and focus on squeezing the glute at the top rather than achieving maximum height.
