3 Core Exercises You Need to Do to Tighten Your Abs, According to a Fitness Trainer

I have been in the fitness industry for over 20 years, and one of the things female clients ask me the most is, how can I flatten my stomach? I have some personal experience trying to flatten my own. After the birth of my children, I suffered from pelvic floor dysfunction, including bladder incontinence, lower back pain, and diastasis recti (separated abs), which led me to develop my passion and specialty in pelvic floor health. I knew I wasn’t stuck to a lifetime of bladder leakage and wanted to create programs that would be accessible to all women so anyone needing help with issues could get it—and also get a strong, lean mid-section. Here's how you can get yours.

The Foundation of a Woman's Core

The pelvic floor is the foundation of a woman’s core. The pelvic floor aids in our bladder, bowel, and sexual function. At least ⅓ of all women will experience pelvic floor dysfunction at some point in their lives, and this leaves the spine and abdominals not functioning optimally. Many women have diastasis recti after pregnancy, and even women who haven’t been pregnant can get it. This causes a separation in the abdominals and will often cause a belly pooch that sit-ups and planks, and many traditional exercises make it worse. Our transverse abdominals act like a corset to balance abdominal pressure and support the spine. If we have diastasis recti, shallow breathing, suck in our stomach a lot (causes gripping and overuse of the upper abs), or a myriad of other issues going on, we can get pelvic floor dysfunction and abs that aren’t working right. The lower abdominals often pooch out; a flat stomach seems impossible, but it is from dysfunction in the core.

Train Your Deep Abdominals

Doing pelvic floor exercises trains your deep abdominals to function well, and diaphragmatic breathing (aka belly breathing) helps with the elasticity of the pelvic floor and abdominal activation. Many recommend Kegels and Kegel exercises to tighten the pelvic floor. While they are appropriate for some women who are overstretched throughout the pelvic floor, for women with a hypertonic pelvic floor or who have parts of the pelvic floor with too much tension, they will make issues worse and even can create new issues. Kegels are concentric contractions and can lead to chronic tension and tightening of the pelvic floor, which can lead to painful intercourse, incontinence, lower back pain, and difficulty achieving orgasm, among other issues. Unless a woman is seeing an internal therapist to monitor tension throughout the pelvic floor, women are not going to know if their issue is too much tension, not enough, or a combination of so many women experience a poor outcome from Kegels. They are also one exercise that doesn’t train the pelvic floor to be dynamic and train its fourteen muscles for optimal strength and elasticity throughout. There are far better ways to train the pelvic floor while at the same time building strength in the entire core, leading to strong and high-functioning abs.

Your Secret Weapon

I love using a stability ball with pelvic floor exercises because the ball activates your deep abdominals and improves stability far better than exercises on a mat or stable object. Pelvic floor exercises that emphasize full body and dynamic movement are optimal. Training your pelvic floor to be strong, toned, and responsive through all planes of motion trains your abdominals to be highly functioning and helps flatten your stomach even without any changes in diet or weight loss. This is because they will engage your transverse abdominals; if you have diastasis recti, they help close that gap for most. Using concentric and eccentric contractions trains the pelvic floor muscles for optimal strength and tension throughout while at the same time helping your posture and helping flatten your abs. They are the secret weapon I have used for over 20 years, and once women realize how effective they are at accomplishing so much, they are hooked.

How My Body Changed and Yours Can, Too

I haven’t done sit-ups, planks, leg lifts, and traditional abdominal exercises in over 20 years, yet my abs are strong and flat. My body completely changed once I started training differently and learned about biomechanics and corrective exercises, and I felt better than ever. My wish for all women is to learn that fitness and good movement/posture are attainable without hours in the gym. Creating balance and good biomechanics leads to improved confidence and carries into our daily life so we show up happier and healthier to live our best lives. So, for any of you ladies wanting a flat stomach, pelvic floor exercises are key.

Looking to transform your core and achieve rock-hard abs in just 60 days? It’s entirely possible with the right plan and mindset. Fitness expert Jeff Nippard, a Canadian natural pro bodybuilder and powerlifter, combines his biochemistry background with a passion for evidence-based training to offer a proven strategy. His approach emphasizes not only effective ab exercises but also the critical role of nutrition and overall lifestyle changes. By focusing on progressive overload training, maintaining a clean diet, staying hydrated, and incorporating some cardio, you can build a strong, visible six-pack. Stick to the plan, stay consistent, and watch your abs become more defined with every workout—and also enjoy insights from Sharon Stewart, AFAA, and NASM to help you get those coveted abs in just 60 days.

Fat vs. Abs

Nippard explains in his popular video the relationship between body fat percentage and ab visibility: "At 30% [body fat], your stomach is much flatter, but you still don't have visible abs. Once you get to 20%, that's where your abs become visible, and at 10% body fat, you'll have a well-defined six-pack."

He adds, "This zone is the six-pack sweet spot where most men want to be between 10 and 20% body fat. This is where you'll have visible abs but not suffer from the nasty side effects of extreme dieting."

Progressive Overload Is a Must

Contrary to what most people think, Nippard in his video underlines the importance of training abs directly: "To get your six-pack to really pop, you'd be much better off doing progressive overload training just like you would for any other muscle. That means loading the ab muscles with weight."

Try Two-Exercise Ab Workout

Nippard, in his video, recommends focusing on just two exercises for optimal ab development:

1. Weighted Crunch: "Do these for three sets of 10 to 12 reps twice per week, taking your last set all the way to failure."
2. Leg Raises: "Do these for three sets of 10 to 20, also twice per week, and also take your last set all the way to failure."

Nutrition is Key

Sharon Stewart, a certified personal trainer, highlights the importance of nutrition for getting visible abs: “Nutrition is 90% of a flat belly. I see people doing hundreds of sit-ups, and I ask them, what are you doing? While exercise is important, it’s what you eat that makes a big difference in your body.”

Stewart suggests eating clean: “Think of your body like a car. The quality of fuel you use affects how well it runs. If you eat poor-quality food, it doesn’t matter how much you exercise; your body won’t be at its best.”

How to Eat For Visible Abs

Nippard agrees, in his video, the importance of nutrition: "You can do the most optimal progressive AB training on the planet, and until you get lean enough, your AB simply won't be visible and that's where your nutrition comes in."

He provides a simple formula for calorie intake: "Take your current body weight in pounds and multiply it by 10 to 12. That's how many calories you'll eat."

Hydration and Intermittent Fasting

Stewart also highlights the importance of hydration and suggests intermittent fasting as a potential strategy: "One of the key factors in achieving a flat stomach is hydration, particularly drinking plenty of water. Hydrating adequately with water, sometimes infused with lemon for added benefits, is essential."

She shares her personal experience: "I changed my eating habits, deciding not to eat until I had completed my activities for the day. Then, I would break my intermittent fast around two o'clock with a protein-rich meal to help burn fat."

Don’t Forget About Cardio

While not essential for fat loss, Nippard, in his video, notes the benefits of including cardio: "Research shows that combining weight training and cardio leads to smaller wastes than just weight training alone. Being more active with cardio will also allow you to eat more calories and more active people tend to be more successful in keeping the weight off over the long term."
