How to: Lie on your left side with your legs straight and your right leg stacked on your left. Position yourself so your weight is resting on your left forearm and the outside edge of your left foot. Your elbow should be directly beneath your shoulder, and your upper arm should be perpendicular to the floor. Align your body so it forms a straight line from your neck to your ankles, and place your right hand on your hip. Lower your hips toward the ground a couple inches, then come back up to start. That’s one rep. Do 15 reps on each side.
Amazingly, exercising the abdominal muscles is far less important than shedding the fat which hides them. Lots of people attain incredible six packs simply by becoming leaner, though sometimes, compound exercises which recruit lots of muscle fibers (which I’m a big fan of), such as deadlifts or squats, may help improve the appearance of the abdominal muscles.
Before you launch into the advanced ab workout, you will want to ease into it with some basic core exercises to warm up the abdominal muscles. The Plank is a great way to begin. The plank provides a simple and effective core warm-up because engages all the muscles of the core from your toes up to your head. Holding the plank requires the activation of all the major ab muscles as well as many stabilizer muscles that are often ignored.
Everyone has six pack abs. They’re there, whether you believe it or not. The problem is that not everyone’s body composition is such that their abs are actually visible. These muscles don’t need to be created – they need to be revealed. Remember our “strongman” example – powerful upper body, mighty arms, and a layer of soft flab around their midsection? Believe me, Mr. Strongman is packing some serious stomach muscles, but like on a lot of us, they’re hidden under layers of adipose tissue. That’s why they’re not visible.
Most men perform the inchworm as a warmup exercise. The move stretches your calves, hamstrings, and thighs, while preparing your muscles for just about any activity. But throw a towel under your feet while you do it, and suddenly the inchworm becomes a grueling core-strengthening move called the inchworm slide. "Sliding the towel to meet your stationary hands activates your abs, hip flexors, and obliques," says Jack. "You'll finish feeling stronger and loose."
To do it: Lie down with a small ball (a small pillow will also work if you don’t have a ball) under your heels, both arms extended over your head, palms facing towards each other. Inhale to prepare as you lift your head, neck, and shoulders off the floor and then exhale as you continue to roll up by drawing in your abdominals, reaching up and over towards the feet. Keep your abdominals contracted, with your spine rounded in a ‘C’ curve, and then inhale to prepare and exhale as you roll down through each vertebra in a controlled movement, keeping your heels pressed evenly into the ball the entire way up and down. Do 15 reps as controlled and precise as you can.
“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
While staying hydrated is important no matter your fitness goals, you absolutely have to drink up if you want to see the abs you’ve been working so hard to sculpt. Your body is two thirds water, and you want to make sure it stays that way, Delbridge says. Keeping your water levels up prevents water retention and helps your body rid itself of toxins and excess salt to reduce boat. And if you’re puffy, your abs aren’t going to look as chiseled as they could. When you hit the urinals, your pee should be pretty much clear.
When guys talk about six-packs, they are really talking about one muscle, called the rectus abdominis. “The rectus abdominis runs from our lower ribs down to the top of our pubic bone, and fibrous bands of tissue break up the muscle along the way to give us the six-pack look we all desire,” explains kinesiologist David Cary, C.P.T., a T4 Coach at Equinox in Chicago. So, if you want to sprout six-pack abs, this is the muscle you need to work.
