That's because it’s insanely hard to get ripped abs. “Every woman’s body is built differently, so it varies, but generally speaking it takes a lot of time and dedication to get those abs to show,” says Amanda Butler, C.P.T., instructor at The Fhitting Room in New York City (and a fitness model who has her own fierce six-pack). “It can take anywhere from three months to a year to get a six-pack, and it’s not just about doing a ton of abs exercises.”
But there's science behind this buzzkill. The rectus abdominis — the muscle that makes the stomach look defined as hell — is typically covered by fat (because that's how humans are made) and isn't affected by things like crunches and planks. "You can work your abs all you want, but if you have a layer of fat over them, the 'pack' can’t be seen," Ball says. And FWIW, that's not a bad thing or something to feel bad about. "It’s very unrealistic for most people to have body fat percentages low enough to see the abs."
Genetically, women have a disadvantage when it comes to that. Their bodies store more fat than men. For good reason, says Calabrese. Women's bodies are designed to bear and nourish babies and fat is the primary energy source to support fetal development. In addition, Calabrese says, men generally lose weight quicker as a result of regular exercise.
Nothing says fit like a washboard stomach. But scoring high-definition abs isn't as easy as cranking out crunch after crunch. To sculpt a stronger, more chiseled core, you need the best ab workout to work the two dozen muscles between your hips and your shoulders in the many ways they function. After all, your abs do more than flex on a daily basis—they stabilize and rotate, too.
There are many ways you can do this move, even including a Pallof press with rotation, but most start at a cable stack with a D-handle just below shoulder height. Grab the handle in two hands, take 4-5 steps away from the pulley, and turn so that your side is facing the plate stack. Without rotating at the hips, press the D-handle straight out, and return back to center; all the while, you'll fight against turning toward the pulley. Be sure to maintain a neutral spine and keep your shoulders down during the entire pressing motion.
This athletic move takes the plank to an all-new level. "It not only improves your core stability, but it targets muscles in your hips, groin, lower back, and often-neglected lower abs," says Durkin. Get your heart pumping by speeding up the movement, or hammer your core muscles by slowing it down. Either way, the exercise will boost your athleticism and will give you something to bare at the beach.
But instead of just trying to perform as many reps as possible, slow down and really focus on the quality of the movement—especially the eccentric, or downward motion, of the exercise, he says. “The eccentric contraction is the most important phase when sculpting any muscle.” Plus, focusing on quality over quantity will help protect your back (some experts say crunches can be potentially troublesome for guys with back issues.)
