Abdominal muscles consist of three layers. The very deepest layer is the transversus abdominis, which acts as the body's girdle, providing support and stability and plays a critical role in exhalation. Next is the rectus abdominis, which flexes the spine. Closest to the surface are the internal and external obliques, which turn the trunk and provide the body with rotation and lateral movement.
Attention to workout rest and recovery, as well as nighttime sleep, is also critical to promote muscle growth and hormone balance. You may find much of your time is spent working out or meal prepping — your social life, hobbies and downtime will likely be compromised. Don't forget, you must also keep up these regimens not just to achieve a six-pack — but to keep one.
And, since the muscle is designed to bring your lower ribs and pelvis closer together or farther apart, you need to work them that way—with crunches and reverse crunches, Cary says. In fact, research commissioned by the American Council on Exercise shows that the crunch works the rectus abdominis better than other common abs exercises including the plank, sit-up, and boat pose.
AthleanX — If I were to recommend you ONE channel, this would be it. Don’t watch anything else, just listen to Jeff Cavaliere. His entire approach towards fitness is something that has come to resonate with me. There’s no bulking-cutting nonsense, pure focus on form, getting the maximum out of each exercise and a lifelong approach towards good, sustainable nutrition. If I wanted a few exercises to target a particular muscle group, this is where I go to first, learn them, try them out in the gym and invariably get results. There’s a ton I’ve learnt from Jeff and couldn’t thank him enough.
Good news: Thanks to some of the best trainers in the country, we’re going to help you out. Below are their favorite abs exercises, along with a few pro tips to ensure that you’re executing each one perfectly. Incorporate them à la carte into your existing routine—or, if you’re feeling ambitious, turn all six into an abs workout circuit. Try two sets of each movement, resting for 30 seconds between each set.
To do it: Stand with your feet planted 3-4 feet apart, toes slightly turned out, hands on your hips. Lower into a plie by bending your knees out over your toes and lowering your hips directly underneath your shoulders. Then, as your straighten back up, slowly lift the right knee up towards the right shoulder. As you go back into the plie, slowly return the foot to the floor. Be sure to move at a very controlled pace to really engage the obliques the entire time—on the way up and on the way down. Do 10 repetitions on the right side, then another 10 repetitions on the left side for a total of 20.
