BICYCLE
Lie flat on the floor with your lower back pressed to the ground. Put your hands beside your head. Bring knees up to about 45- degree angle and slowly go through a bicycle pedal motion. Touch your left elbow to your right knee, then your right elbow to your left knee. Keep even, relaxed breathing throughout.
1. Lie on the floor and lace your fingers behind your head.
2. Bring the knees in towards the chest and lift the shoulder blades off the floor without pulling on the neck.
3. Straighten the left leg out while simultaneously turning the upper body to the right, taking the left elbow towards the right knee.
4. Switch sides, bringing the right elbow towards the left knee.
5. Continue alternating sides in a 'pedaling' motion for 1-3 sets of 12-16 reps.
EXERCISE BALL CRUNCH
The exercise ball is an excellent tool to strengthen the abs and is the third most effective move for targeting the rectus abdominis. What makes this move a bit more effective than crunches on the floor is that the legs are often involved in floor crunches. On the ball, the abs do more work, but you still involve the entire body to help stabilize you throughout the movement, a nice bonus that floor crunches don't always offer.
How to:
1. Lie on the ball, positioning it under the lower back.
2. Cross your arms over the chest or place them behind your head.
3. Contract your abs to lift your torso off the ball, pulling the bottom of your ribcage down toward your hips.
4. As you curl up, keep the ball stable (i.e., the ball shouldn't roll).
5. Lower back down, getting a stretch in the abs, and repeat for 1-3 sets of 12-16 reps.
