Movement:
Lie in a supine position (on your back), with your knees bent and feet flat. Raise one leg off the floor (not too low) and gently lift your hips till your body forms a straight line from shoulder to knee.
Contract the glutes and hamstrings as you pause for a few seconds. Drop down slowly and repeat.
For people with lower back problems, careful to keep the elevated leg too low. If there’s still a slight arch in the lowerback you can lift your head slightly to push the lowerback into floor for more support.
