Straight-Leg Raises to the Front

Lie face up on your back.

Gently squeeze your core muscles. Be sure to keep breathing while doing this.

Keeping your knees straight, slowly lift one leg up about half a foot (15 cm) off the floor.

Hold that leg in that position for two to three seconds, and then slowly lower it back to the floor.

Repeat the above steps for the opposite leg.

Slowly do at least 10 to 15 reps, alternating and relaxing between both legs.
