Lie on your back with a resistance band looped around your foot to be exercised.
The other end of the band should be secured to a solid object at your feet with your head furthest away.
Ensure there is tension in the band while your leg lies straight on the floor.
Tighten your abdominal muscles.
Against the resistance of the band, draw your knee up towards your chest, bending at the hip and knee.
Control the movement as you slowly return to the starting position, and then repeat.
