A two-pack or four-pack is great, but why not go for the gusto and work for the entire six-pack? Chadwell said, "Your lower abs are going to put up a fight! They are the most stubborn, so you have to include a core exercise that targets your lower abdominals. That's where the double crunch comes in."
The double crunch, as the name suggests, does two jobs simultaneously. It strengthens your upper and lower rectus abdominis.
How to Do the Double Crunch:
- Lie on the floor on your back.
- Place your hands on the back of your head so that you are cradling it.
- Lift your legs so that your knees are bent at a 90-degree angle and your lower legs are parallel to the floor.
- Contract your abs to lift your hips off the floor while simultaneously raising your upper body off the floor. You are doing both a crunch and a reverse crunch at the same time. Don't lift your head with your hands. Use your upper abs.
- Hold for a one count, and slowly return to the starting position.
- Repeat for 25 reps.
