Back Exercises: Knee Lift
To start, lie on your back with your knees bent and feet flat on the floor. Don't press your neck or lower back to the floor. Breathe deeply. You should feel comfortable and relaxed in this position:
- Start by tightening your abdominal muscles.
- Lift one bent knee off the floor 2 to 4 inches.
- Hold for 10 seconds. Return to start position.
- Repeat 3 times.
- Switch legs.
