Having a strong core is important to your overall health.1 But what does it mean to have a strong core? Most people would say it’s sporting 6-pack abs or a flat stomach. Contrary to what many men and women believe, your core is so much more than your abdominal muscles. And just because someone has an aesthetically pleasing midsection doesn’t mean that he or she has a strong core.

Read on to discover exactly what the core is, the benefits of strengthening it, and core exercises and workouts you can do from home that will help you reach your health and fitness goals.


Core ≠ Abs

For years, people have used “core” and “abs” interchangeably—but they are not the same thing. The abs are simply the abdominal muscles, which in include:

  • the rectus abdominus (the top layer of muscles that create that much-desire 6-pack)
  • the transverse abdominus (the deep muscles that wrap from the sides of the lower back around to the front)
  • the internal and external obliques (the muscles on either side of the abdomen)



Although an important part of the core, the abs are just that—a part. According to Paul Goodman, strength and conditioning coach for the Chicago Blackhawks, “the core is a very broad scope of muscles that work in union with one another to create and stabilize movement.”2 In other words, "the core refers to the abdominal muscles, the spinal muscles (the muscles that run along the back of your trunk), the pelvic floor muscles (the muscles at the base of your trunk), and the diaphragm (the muscles at the top of your trunk)," says Karen Barbieri, founder of Pietra Fitness.

While there is nothing wrong with strengthening your abdominal muscles, the goal should always be to have a strong body. If you only focus on your abs, “your back isn’t going to be as strong, and so there’s going to be an imbalance in your body,” says celebrity trainer Anna Kaiser. “You want them to be strong together and work together, and not have one overcompensate.”3


Benefits of Core Conditioning

Conditioning your core not only improves posture, which contributes to a trimmer appearance, but also . . .

  • boosts the effectiveness of workouts
  • reduces the risk of injuries4
  • makes it easier to perform everyday physical activities, such as retrieving an item off a high shelf, lifting a child, swinging a golf club, and bending down to tie your shoe
  • leads to better balance and stability
  • tones your abdominal muscles
  • improves back pain5


On the other hand, weak core muscles can lead to poor posture, injury, fatigue, and lower back pain.6 To avoid these health setbacks and achieve a truly strong core, it’s important to perform exercises that work allthe muscles in the core.


9 Exercises that Strengthen the Core

Core exercises are an important part of a well-rounded fitness program,7 and they train the muscles in your pelvis, lower back, hips, and abdomen to work together. But when most people train what they think is the core, they gravitate toward isolation exercises that isolate a specific muscle—such as the abdominals—in order to create hypertrophy in a desired area.8 The problem with isolation exercises is that they don’t utilize the core muscles in  ways that transfer to real-life activities outside the gym. Functional training, on the other hand, puts emphasis on most, if not all, of the core muscles and is more relevant to movements you perform on a regular basis.9

Any exercise that involves your abs and back muscles in a coordinated fashion counts as a functional core exercise.10 For example, maintaining a stable trunk while doing bicep curls or overhead presses with free weights can train and strengthen your core muscles.

You can also perform specific core exercises:

  • planks (forearm, straight arm, side, jacks, etc.)
  • sit ups
  • half backbends
  • reverse crunches
  • arm and leg raises
  • bicycles
  • pike pose
  • stability ball pikes
  • stability ball knee tucks
  • stability ball push ups


When trying any of these exercises, be sure to start slow, go at your own pace, stop if you experience any pain, and breathe. It’s important to concentrate on doing the exercises correctly, not on how quickly you can do them or how many reps you can perform.
