Pelvic Tilt (Abdominal Exercise 1 of 8)
The abdominal exercises selected for the BEST exercise program are important for maintaining posture and stability of the lumbar spine. The BEST researchers recommend performing lower abdominal exercises rather than the classic sit-up or curl.

IMPORTANT INFORMATION: Please read before performing exercises.
Execution
Lie on your back with your knees bent, and your feet apart and flat on the floor.
Contract your lower abdominals so that your hips tilt down and your buttocks lift slightly off the floor.
Do not use your legs to raise your buttocks. The small of your back should press into the floor.
Hold the pelvic tilt for 10 seconds. Repeat 6 times.
