Best Ab Exercises Using Weights

This lunge variation works the entire body, and adding the twist ensures that your abs get a little extra attention.

• Stand with your feet hip distance apart. Hold a five- to 10-pound medicine ball with both hands with your arms outstretched in front of you.
• Keep your core stable, and take a large step back with your right foot, planting your foot and then lowering your body until both legs are bent in right angles.
• As you sink into the lunge, twist your torso to the left.
• Bring your torso back to center, and exhale as you straighten your legs. Bring your feet back together, and then step back on your left leg, twisting to the right.
• This completes one rep. Do 10 reps for a set, and do at least two sets.
