A healthy diet is important but variety in fitness routine goes a long way when trying to tone the mid-section. Keep in mind the core goes far beyond the popular ab crunch. Change positions and target the entire mid section. For best results: 45 seconds per exercise, or 10 reps per side and repeat 3 times.
Plank—inside leg toe touch
Bring the leg inside and across, as close to the opposite hand as possible. Try to keep the hips parallel to the ground. Alternate legs.
Raised Plank—shoulder touch
Elevate the legs from a chair to engage the core even more. Bring one arm up to touch the opposite shoulder. Repeat on other side. This can be done without raising the legs or can be done from the knees.
Oblique Ball Cross Over
Hold a medicine ball—or anything with added weight in front—with arms extended. Slowly, with straight legs, bring both legs up and move to one side of the ball. Slowly lower the legs and repeat on other side.
