Bridge with elastic band
Lying hip lift in which the hips rise and lower with an elastic band above the knees.
Lie on your back with your knees bent and feet hip-width apart. Place the band around your thighs just above the knees. Keep your knees slightly apart and rest your arms on the floor.
Press your feet into the floor and lift your hips. Keep your knees slightly apart and lift until your body forms a straight line from shoulders to knees. Lower your hips slowly again.
