START: Lie faceup with your arms alongside your body, palms down. Raise your legs so your hips and knees form 90-degree angles.
MOVEMENT: Contract your abdominal muscles to pull your knees toward your chest and your pelvis off the floor. Hold for a count and slowly return to the start.
BONUS TIPS:
>> Shoulders remain flat on the floor at all times.
>> Rotate your pelvis completely off the floor for maximum contraction.
>> Hold the peak contraction for two seconds or more.
>> Once you can complete 12-15 reps with ease, try holding a medicine ball between your ankles for added resistance.
