Core Exercise - Hip Flexion with knee extension

  1. Lie flat on your back with your knees and hips bent up so that there is a small space between the hollow of your back and the floor.
  2. Inhale to prepare and while exhaling engage your core.
  3. Inhale again and as you exhale lift one foot off the floor, bringing the knee towards the chest.
  4. When you reach 90 degrees of hip flexion, straighten the knee.
  5. Return back to the start position by bending the knee and then extending the hip until the foot is on the floor again.
  6. Repeat 5-10 times, alternating legs.
