How to Do Donkey Kicks to Build Your Booty
Like the animal for which they’re named, donkey kicks get no respect. All you’re lifting is your leg, after all — how hard can that be? And who wants to do an exercise named for a bucktoothed ass in a straw hat, usually portrayed as the mount for someone’s diminutive sidekick?
But hold on there, partner: Like that sidekick, donkey kicks — also known as the quadruped hip extension — are underappreciated workhorses. They fire up lazy lower-body muscles, improving mobility and ensuring the long-term health of some of your most vulnerable joints.
Here’s how to do donkey kicks with proper form.
Donkey Kicks: Step-by-Step Instructions
- Get down on all-fours, with your hands directly below your shoulders and knees directly below your hips. Your back should be flat, your neck neutral.
- Keeping your arms straight, core engaged, and knees bent at a 90-degree angle, raise your right knee off the floor and press the sole of your right foot up toward the ceiling. Squeeze your right glute (butt muscle) as hard as you can at the top of the movement.
- Reverse the move, lowering your right knee to the starting position.
- Repeat for the prescribed number of reps, making sure to perform an equal number with each leg.
Tips for Donkey Kicks
The most common mistake made when performing the donkey kick is overarching the spine in an attempt to raise the lifted leg higher.
That isn’t necessary: The target muscles are the glutes — not the lower back — so you won’t need to lift your leg such that you’re arching your back excessively.
Check this tendency by squeezing your abdomen hard as you approach the top of the move. This’ll make sure you’re activating your core muscles and keeping your pelvis stable.
Variations on the Donkey Kick
Once you’ve got the traditional donkey kick down, build on it with any of these alternate takes.
1. Double-leg donkey kick (mule kick)
This two-legged version, described in detail here, requires additional explosiveness and athleticism.
2. Straight-leg donkey kick
Start with your leg extended straight behind you, toes pointed toward the floor instead of upward.
3. Pilates leg kick
A similar exercise, performed in the prone (facedown) position, in which you curl your heel upward and lift your leg.
4. Resistance band donkey kick
The base move performed with a band around your thighs, which provides additional resistance to the lifting leg.
5. Circling donkey kick
The base move, but instead of lowering your leg after lifting it, you circle your thigh out to the side as far as possible to help mobilize your hip joint in all three planes of motion.
6. Weighted donkey kick
The base move performed with ankle weights.
Muscles Targeted by the Donkey Kick
Donkey kicks mainly work your gluteus muscles: the gluteus maximus, medius, and minimus.
“The donkey kick is so named because it mimics the animal’s signature movement,” says Trevor Thieme, C.S.C.S. “But true to the animal’s nickname, it will also help you sculpt a great… you get the idea.”
The target muscle in the donkey kick is your gluteus maximus — the largest of the butt muscles — whose primary job is to extend your hip joint, also known as hip extension (think: getting up from a seated position).
Helping out are the two smaller glute muscles, the gluteus medius and minimus, and the hamstrings — the muscles on the backs of your thighs — which assist the glutes in extending the hips.
In addition to helping you look better from behind, strong glutes and hamstrings help support your posture, protect your lower back and knee joints, and improve your speed and power when you run, jump, and play sports.
