Lie on top of a foam roller so that your pelvis, spine and head are supported.
Bend your knees, place your feet flat on the floor and rest your arms by your sides, hands on your hips.
Lift one leg into a tabletop position, so that your knees and hips are at 90 degrees.
Hold briefly then return your leg back to the ground.
Repeat on the opposite side.
Maintain a neutral spine and engage your deep abdominal muscles throughout this exercise to maintain balance and stability.
