Even though your rectus abdominus is the muscle you want to see when you look in the mirror, your inner core muscles, including your internal obliques and transverse abdominis, are the foundation for your six-pack. “You would not build a mansion on a weak foundation, so don’t try to build a six-pack on a weak core,” Cary says. This is when you’ll want to try out some more creative core workouts like planks, dead bugs, core twists, and farmer’s walks, he says. All of these tap your core’s ability to stabilize, rather than crunch, your core.
To do it: Start with feet in a wide stance, knees bent, arms up on guard. Keeping your lower body still, quickly lean your upper body to the right, then come back through the center and lean to the left. Repeat lean back to the right. Next, lower your upper body, from the right around to the left side, making a half circle with your torso. Return to start position. That’s one rep. (Tip: it helps to keep a steady rhythm with this move, think—or say aloud—1, 2, 3, weave to help you keep your tempo). Repeat 10 times total, alternating starting on the right and left sides.
To do it: Lie on your back with your knees bent, feet flat on the ground. Bring both arms overhead and hold onto the bottom of couch or a heavy medicine ball (as shown). Cross your right ankle on top of your left knee. Exhale and lift your legs in (in the same cross-legged position) as close to your chest as possible, lifting your hips and lower back off the floor. Inhale and slowly return to the starting position. That’s one rep. Try for up to 15 reps with the right leg, then repeat on the left.
“For me, getting a six-pack was about paying attention to what I was eating and lifting heavy weights at CrossFit. I do have a semi-strict diet, and I loosely count macros (focusing on daily carbs, protein, and fat intake rather than blindly counting calories) to stay balanced and on track. It sounds like a lot of work, but it really isn’t. Eventually, it just became a part of my lifestyle, and it’s something I enjoy doing. I even started a custom meal-plan business based on macros because I had such great results!” —Tina Haupert, @carrotsncake
