8 Exercises That Flatten Your Belly (Without a Single Crunch)

Crunches were once the answer to sit-ups, the gym warm-up of our elementary school days. Now both abdominal exercises have a bad rap in the fitness community. The repetitive flexing of the lumbar spine, or lower back, has been implicated in back injuries as serious as disc hernias. The following exercises can help flatten your belly while minimizing pain.

Core stability exercise: the plank

Nolan Lee, DC, MSAC, CES, E-RYT, is a big proponent of core stability exercises like the plank and its many variations. One plank favourite is to hold high plank (arms extended versus on forearms) and alternate a weight between each hand. The weight should sit next to one hand and be pulled across the body with the opposite hand. Repeat this exercise for one minute.

“Alignment of the spine should be neutral to maintain ideal core activation,” Lee says. “A good point of focus is the pelvis. If you can keep the pelvis neutral, not tilting it forward or backward, the low back should remain neutral. Plank can be a good way to work on a neutral, stable spine.”

Jess Fritsche, an ACSM certified Health and Wellness specialist and NCCPT Personal Trainer, reminds us to breathe. “Exhale while you lift the weight and inhale while you return to start position or relax,” she says.

Core stability exercise: the McGill curl up

To avoid creating too much flexion in the lumbar spine, Lee recommends the McGill curl up. To complete this movement, lie on your back with one leg straight and one leg bent. Place your forearms and hands under your low back. Lift your head, chest and shoulders off the floor as much as you can without jutting out your chin.

“Everything moves in one piece like there is a board under you, from the tailbone to head. You might not lift very far, but that is okay,” Lee says. Do two sets of 10, switching legs between sets.

Core stability exercise: marching

For those just building a fitness routine and a foundation for more complex moves, Brent Locey, NASM, certified personal trainer and SoulCycle instructor, recommends core stability exercises, such as marching.

To complete this exercise, lie on the floor with your knees together and bent, feet flat. Lift one leg at a time, maintaining the bend, and draw the knee as close to the abdomen as possible. Locey says it’s important to practice the “drawing-in maneuver” during all core exercises. To draw-in, pull the area below your navel towards your spine, while maintaining a neutral spine. “I often coach this by placing your hand on that area and noticing as you inhale how your stomach draws toward your back,” Locey says.

“The most important thing to focus on, especially for beginners, is making sure they have adequate balance and stability… [Otherwise] you could easily injury yourself immediately, or develop long-term injury because your body starts to overcompensate in the wrong areas.”

Core stability exercise: two-leg floor bridge

Another great exercise for foundation work is the two-leg floor bridge. Lying on the floor with your knees together, bent, feet flat, and arms by your side, lift your pelvis and hips off the so that your knees, hips, and shoulders are all in line. Slowly lower to the floor and repeat. Locey recommends doing one to four sets of this core stability exercise, with 12-20 repetitions.

Core strength exercise: pulse-ups

A pulse up is a progression from a core stability exercise; it is considered a strength core exercise. Lying down face up, bring your legs toward the ceiling, with the soles of your feet adjacent to the ceiling. Lift your legs, posterior, or rear, and low back off of the ground to “pulse” up as high as you can. As you return to the starting position, Locey says to brace your core to limit the amount your legs fall toward the ground as much as possible.

Core strength exercise: mountain climbers

Mountain climbers are also strength core exercises, a progression from stabilization exercises, says Locey. Starting in a high plank position, begin to run in place, bringing your lead knee as close to the same-side elbow as possible. As you alternate your legs, resist the urge to lift your hips and posterior, maintaining a solid brace and engagement of your core throughout. Locey says this is a common mistake. “If an exercise is too advanced or difficult, or if you start to fatigue, our bodies often try to compensate and continue to work through the exercise by finding the path of least resistance, [like] losing proper form to make the movement easier.”

Core power exercise: soccer throw

Once you’ve built a foundation and your progression continues, move into power core exercises like this one. To complete a soccer throw, stand tall with a medicine ball (weight of your choice) overhead. Quickly throw the ball toward the floor and follow through with the arms. Complete two to three sets of this power core exercise, repeating the steps for eight to 12 repetitions.

Your abdominals should be engaged, says Fritsche. The most common mistake she sees is that people go through the motions and don’t focus on tightening and engaging the core muscles. Locey describes it as a great total body exercise. “It is working not only your upper and lower abs as you go from a total stretch with your hands above [your head], to squeezing your abdominals as you forcefully throw the ball down to the floor, but [it] also works your triceps and latissimus dorsi (back).”

Cardio and healthy eating are a way to flatten your abs without a single crunch exercise

Finally: cardio and healthy eating

While targeting your ab muscles, remember they are protected by the fat and tissue surrounding them. A common mistake Dr. Lee sees when clients are working on flattening the belly is working on the abdominal muscles but forgetting about the layer of fat that covers them. “You could have great muscles covered with a layer of fat. Calorie burning activities like spinning, HIIT, cardio workouts are a great addition, and diet will need to be addressed trim down the belly most effectively,” Lee says.

“I definitely think nutrition and exercise are equal partners in a goal of a flatter midsection,” says Locey. “You can do all the abdominal and core work you want for hours a day and every day of the week, but if you aren’t eating well, you will mask that muscle growth with layers of fat. As a fan of pasta, cheeseburgers with buns, and bagels, I will say you can have your carbs and get your flat belly too. Carbohydrates themselves are not the things holding people back from having a flat belly; it is the amount in which they are consumed. So as long as you live by the old phrase ‘everything in moderation,’ you can still see results.”
