Master donkey kicks with correct form. Learn muscles worked, common mistakes, and evidence-based benefits for glute strength and activation.
Donkey kicks are a targeted hip extension exercise performed in a quadruped position that isolates the gluteus maximus more effectively than many compound movements. The name comes from the visual: one leg kicks upward and backward like a donkey’s hind kick — though the actual movement should be far more controlled than that image implies. What makes donkey kicks uniquely valuable is the knee position. By keeping the knee bent at 90 degrees throughout the movement, the hamstrings are mechanically shortened and therefore minimally involved, placing nearly all the hip extension demand on the gluteus maximus.
This muscle isolation matters. In most compound lower-body exercises — squats, lunges, step-ups — the hamstrings and quadriceps share the load with the glutes, often compensating for glute weakness without the person knowing. Donkey kicks remove this compensation option. If the glute is weak, the movement reveals it immediately. This makes the exercise valuable both as an assessment tool and as a targeted corrective exercise.
The contrarian reality is that many people perform donkey kicks incorrectly by arching the lower back to lift the leg higher. This lumbar extension substitution effectively removes the glute as the primary mover and loads the spinal erectors instead. The result is back fatigue with minimal glute benefit — the opposite of the exercise’s purpose. Westcott (2012, PMID 22777332) demonstrated that isolated resistance training of specific muscle groups produces meaningful strength and functional improvements when performed with correct technique and progressive load.
Donkey kicks are particularly well-suited as a pre-activation exercise before compound lower-body training. Research on glute activation suggests that performing targeted glute isolation before squats or lunges may improve glute recruitment during those compound movements — addressing the pattern of “glute amnesia” associated with sedentary lifestyles.
Correct donkey kick technique is defined by two key principles: maintaining the 90-degree knee position throughout the movement and lifting through glute contraction, not spinal extension. Every other technical point is secondary to these two.
Begin in the quadruped position: hands and knees on the floor. Wrists should be stacked directly beneath the shoulders — not in front of them. Knees directly beneath the hips. Spine in neutral alignment — not rounded (which would load the spinal flexors) and not arched (which would load the extensors). Eyes look down at the floor approximately 12 inches ahead of the hands. This aligned starting position is the foundation for clean movement.
Place both knees down lightly and identify the leg you will work first. Flex that knee to approximately 90 degrees — this is the position you will maintain for every repetition. Feel the engagement difference: if you straighten the knee, the hamstrings become more involved; if you keep it at 90 degrees, the movement becomes almost purely a glute hip extension.
Initiate the lift by contracting the glute of the working leg. Do not use momentum, do not shift your weight, and do not press through the supporting hand. The contraction happens in the glute only. Drive the heel toward the ceiling. The thigh rises in hip extension — the knee angle remains constant at 90 degrees. Think of the foot pressing up toward the ceiling, not the knee swinging backward. The distinction creates a more direct glute contraction path.
Continue lifting until the thigh reaches approximately parallel to the floor — for most people, this is where the glute reaches its maximum voluntary contraction before the lower back begins to arch compensatorily. If you notice the lower back arching (anterior pelvic tilt) before reaching parallel, stop at that point. The maximum range of motion without compensation is your working range — not the maximum possible height.
At the top position, squeeze the glute firmly for 1 second. This isometric hold at peak contraction increases time under tension and amplifies the training stimulus. Then lower the knee slowly — approximately 2 seconds — back toward the floor. Do not let the knee touch between reps. Maintaining the hover keeps continuous tension on the glute throughout the set. Complete all repetitions on one side before switching.
According to ACSM (2011), movement quality and progressive demand are what turn an exercise into a useful stimulus. HHS (2011) supports that same principle, which is why execution, range of motion, and repeatable loading matter more than novelty here.
Beginner: Slow Tempo Donkey Kick 3 seconds up, 2 seconds hold, 3 seconds down. 10–12 reps per leg, 2 sets. Slow tempo with a beginner’s range of motion focuses on developing the mind-muscle connection to the gluteus maximus. Many beginners discover they cannot feel their glutes working initially — the slow tempo helps establish this neural awareness before adding load or volume.
Beginner: Forearm Donkey Kick Perform the movement with forearms on the floor instead of hands. The lower position reduces demand on the wrists and changes the trunk angle slightly, making it easier to maintain neutral spine. Appropriate for individuals with wrist discomfort.
Intermediate: Standard Donkey Kick with 1-Second Hold Full range, 1-second isometric hold at top, controlled lowering. 15–20 reps per leg, 3 sets. This is the reference standard for intermediate practitioners. The Physical Activity Guidelines for Americans (2nd edition) recommend muscle-strengthening activities of all major muscle groups on ≥2 days per week — donkey kicks provide specific glute strengthening within this framework.
Intermediate: Resistance Band Donkey Kick Loop a resistance band around both thighs just above the knees. The band adds progressive resistance as the hip extends — greater resistance at the top position where the glute is most capable of generating force. Schoenfeld et al. (2015, PMID 25853914) found that resistance-band training produces comparable hypertrophic stimulus to free-weight training at equivalent effort levels, making bands an effective progression tool.
Advanced: Ankle Weight Donkey Kick Wear a 1–3 kg ankle weight on the working leg. This directly increases the external resistance against which the glute must work, providing a clear progressive overload stimulus. Schoenfeld, Ogborn, and Krieger (2017, PMID 27433992) demonstrated the dose-response relationship between training load and muscle adaptation — ankle weights are a simple way to apply this principle to bodyweight glute exercises.
Advanced: Fire Hydrant to Donkey Kick Combo From quadruped, perform a fire hydrant (hip abduction, keeping knee bent), then transition to a donkey kick (hip extension). The combination trains both gluteus medius (abduction) and gluteus maximus (extension) in a single flowing movement.
Gluteus maximus (primary): The gluteus maximus is the primary mover and the intended target of donkey kicks. It is the largest muscle in the human body and the primary driver of hip extension. The 90-degree knee position mechanically shortens the hamstrings, removing them from the movement and isolating the glute. At the top of the movement — when the thigh reaches parallel — the glute achieves near-maximal contraction at this body position.
Hamstrings (secondary): Despite the 90-degree knee position minimizing hamstring involvement, the biceps femoris, semimembranosus, and semitendinosus still contribute as secondary hip extensors. Their role increases if the knee begins to straighten during the kick — which is why maintaining the 90-degree position is the central technical cue.
Core (stabilizer): The transverse abdominis, obliques, and spinal erectors work isometrically to prevent the trunk from rotating and the lower back from arching as the leg lifts. The core stabilization demand is real and cumulative over multiple sets. This is why the exercise also serves as indirect core training.
Shoulders (weight-bearing stabilizer): Both hands bear weight throughout the exercise. The anterior deltoids, serratus anterior, and rotator cuff work continuously to maintain the pressed-palm position and prevent shoulder collapse.
Opposite glute (stabilizer): The standing leg’s glute works isometrically to maintain hip level. This stabilizer role is often overlooked but contributes meaningfully to the exercise’s overall glute training effect.

Mistake 1: Arching the lower back to lift higher The most prevalent and consequential error. Anterior pelvic tilt and lumbar hyperextension during the kick means the spinal erectors, not the glute, are doing the lifting. The glute receives minimal stimulus while the lower back is loaded. Fix: Before each rep, consciously contract the core and think “keep my back flat.” Place one hand on the lower back if needed to detect arching. Stop the lift the instant arching begins — that is your actual range of motion.
Mistake 2: Straightening the knee during the kick Some practitioners kick with a straight leg, which turns the exercise into a prone leg raise — a hamstring and erector movement rather than a glute isolation. Fix: Focus on feeling the sole of the foot drive toward the ceiling while the knee stays at 90 degrees. The mental image is “stomp the ceiling” not “kick backward.”
Mistake 3: Moving too quickly Fast, rhythmic donkey kicks use momentum rather than muscle. The glute barely works; the movement is driven by inertia. Fix: Count the tempo: 2 seconds up, 1-second hold, 2 seconds down. Remove all momentum. The controlled tempo ensures the glute is the mover on every repetition.
Mistake 4: Rotating the hip outward at the top External hip rotation at the top of the movement (turning the knee out to the side) recruits the piriformis and external rotators rather than the gluteus maximus. Fix: Keep the knee pointing directly downward throughout the movement. The kicking leg’s knee should face the floor, not the side wall.
Mistake 5: Neglecting the lowering phase Dropping the knee back to start without eccentric control skips the lengthening phase of the exercise. Eccentric training is associated with greater muscle damage and subsequent adaptation than concentric-only training. Fix: Count 2 seconds on the lowering phase on every repetition, maintaining tension throughout.

Gluteus maximus strength: Donkey kicks are one of the few zero-equipment exercises that directly targets the gluteus maximus with meaningful isolation. Westcott (2012, PMID 22777332) demonstrated that progressive resistance training of specific muscle groups produces meaningful improvements in muscular strength and functional capacity. Regular donkey kick training, with progressive overload through resistance bands or ankle weights, may produce measurable glute strength gains.
Glute activation for compound movements: Weak or inhibited glutes are a common pattern in sedentary adults — often called “gluteal amnesia.” Performing donkey kicks before compound lower-body exercises may improve glute recruitment during squats, lunges, and hip hinges, potentially improving performance and reducing compensatory load on the lower back and knees.
Low-back pain association: The gluteus maximus is a primary stabilizer of the lumbo-pelvic-hip complex. Weak glutes are associated with anterior pelvic tilt and increased lumbar spine loading during daily activities. Strengthening the gluteus maximus through exercises like donkey kicks may be associated with reduced low-back discomfort over time, as noted in the evidence base reviewed by Westcott (2012, PMID 22777332).
Progressive overload accessibility: Schoenfeld et al. (2015, PMID 25853914) found that low-load, high-repetition resistance training produces hypertrophy comparable to heavier loads when taken to near-failure. Donkey kicks with resistance bands or ankle weights fit this model: accessible progressive overload without gym equipment.
Contrarian perspective: Donkey kicks alone are insufficient for complete glute development. The gluteus maximus responds most powerfully to high-load hip extension patterns like hip thrusts, squats, and Romanian deadlifts, where the load is heavier and the range of motion is greater. Schoenfeld, Ogborn, and Krieger (2017, PMID 27433992) showed dose-response relationships between training volume and hypertrophy that bodyweight-only donkey kicks cannot fully satisfy for advanced trainees. Donkey kicks are best used as activation and accessory work, not as primary glute development exercises.

Donkey kicks place sustained load on the wrists, knees, and lumbar spine. Individuals with knee pain, wrist injuries, or lower-back conditions should modify the exercise or consult a healthcare professional. The forearm variation reduces wrist loading. Avoid the arching pattern described under common mistakes, as lumbar hyperextension can aggravate existing back conditions. Stop immediately if you experience sharp joint pain.

3 questions answered
Donkey kicks primarily target the gluteus maximus through hip extension. The hamstrings assist as secondary movers. The core, shoulders, and opposite glute work as stabilizers. Keeping the knee at 90 degrees minimizes hamstring involvement and maximizes glute isolation.
Donkey kicks can contribute to glute development when performed with full range, controlled tempo, and progressive overload. Schoenfeld et al. (2015, PMID 25853914) found that even lower-load exercises produce hypertrophy when performed with sufficient volume. Resistance bands or ankle weights.
Target 15–20 reps per leg per set, 3 sets, with 30-second rest between legs. Beginners start with 10–12 reps. Focus on feeling the glute contract — not on completing reps with compensatory lower-back arch. Slow tempo (2 seconds up, 2 seconds down) increases muscle tension.
