Glutes
Quadruped Hip Extension
The Quadruped Hip Extension is a strength exercise with no equipment for your glutes. Share of the load in the Zulta muscle model: gluteus maximus 69%, gluteus medius 9% and hamstrings (biceps femoris) 6%.

How to do it
- Start on all fours on a mat with hands under your shoulders and knees under your hips.
- Brace your core and keep your neck in line with your back.
- Straighten one leg behind you with the toes lightly touching the mat.
- Lift the straight leg until it is level with your torso, squeezing the glute.
- Lower the leg under control until the toes tap the mat and finish all reps before switching sides.
Tips
- Reach the heel long behind you instead of up.
- Imagine a glass of water on your lower back that must not spill.
Common mistakes
- Lifting the leg above the level of the torso so the back arches.
- Shifting the hips toward the supporting side.
- Letting the head drop toward the floor.
Muscles worked by the Quadruped Hip Extension
Share per muscle in the Zulta muscle model. The model spreads the load of one rep over 40 muscles, based on EMG and biomechanics research.
A bent knee keeps the hamstrings short. Extending one hip backward from standing or all fours isolates glute max; the hamstrings assist more when the knee is straight.
