Hip extension involves some of your strongest muscles, the hip extensors. It is an important part of stabilising your pelvis, and is required for much of your daily movement.
Lay down on the floor with your knees bent at 90 degrees and feet placed flat on the floor shoulder width apart.
Using your glutes, raise your hips off the floor by pushing through the floor with your heels keeping your feet in position. Ensure your knees remain at hip width apart.
You should be in a bridge position from the back of your shoulders to your knees. Keep your glutes under tension for a count of three.
Lower your hips to return to your starting position. Repeat.
Keep your knees in the correct position by holding a yoga block, roll up a thick towel or drink bottle between them.
