Fire Hydrants
The fire hydrant is a bodyweight glute exercise performed on all fours that targets the glute medius through a lateral leg raise. The movement improves hip abductor strength, hip joint mobility, and pelvic stability, and is commonly used in warm-up and rehabilitation routines.
How to do it
- Begin on all fours with your hands under your shoulders and knees under your hips.
- Keeping your knee bent at 90 degrees, lift one leg out to the side as high as comfortable.
- Pause at the top and squeeze the glute of the raised leg.
- Lower the leg back to the starting position in a controlled manner.
- Repeat for the desired reps before switching to the other leg.
Form cues
- Stack your hands under your shoulders and knees under your hips.
- Keep your knee bent at a 90-degree angle throughout the movement.
- Lift your leg out to the side without shifting your torso sideways.
- Squeeze your glute at the top of the lift.
- Lower your leg with control back to the starting position.
Breathing: Inhale as you prepare on all fours, and exhale smoothly as you lift your leg to the side.
Common mistakes
- Twisting the torso to lift the leg higher reduces activation in the target glute muscle.
- Rushing through the movement uses momentum instead of muscle strength.
- Dropping the head and rounding the lower back compromises spinal alignment.

What muscles do fire hydrants work?
Fire hydrants primarily target the gluteus medius on the outside of your hip, along with your core and inner thighs for stability.
Why do I feel this in my lower back?
Feeling it in your lower back usually means you are twisting your torso to lift the leg higher. Keep your core tight and limit the range of motion to your hips.
Can I do fire hydrants every day?
Yes, as a bodyweight movement they are generally safe for frequent practice, but 2 to 3 times a week is plenty for strength gains.
