The “core” is a fitness buzzword that has rung in people’s ears for some time now. If you have been in the gym in the past 10–15 years, you have heard about the importance of a strong core in performance and for activities of daily living. And it’s so true: a weak center can lead to many issues throughout the entire body, mainly low-back pain and tight hips. I am not reporting anything new here; a strong trunk is super, super important!
Core Defined
Gray Cook of FMS posed a question once:
“While driving in your car, what would you rather fail, the engine or the brakes?”
Your core is the brakes for your body. Being able to stop movement as opposed to creating movement is the important function of the musculature of the trunk.
Let’s back up for a second and define the core. The definition has been argued for years on message boards, social media, and countless blogs, but I define the core as pretty much everything minus your extremities—chin to knees. The abs, glutes, obliques, and lats are all major assets of the core system. The trunk serves as your stability, your brakes, the glue that holds everything together and keeps you strong.
Group Fitness for Your Core
In recent posts, we have demonstrated core strategies such as marching, crawling, and dead bugs as great ways to get the job done on your own; but what if you love exercising in a group and want to target your core?
Les Mills CORE (was CXWORX) is a 30-minute group fitness class that is centered around your center. It is a challenging core workout that utilizes resistance tubing and plate weight in an array of different ways. Exercises are performed standing and on the ground, adding many dimensions to your training. Each class begins with a warmup and can consist of up to five different core segments all choreographed to music.
How to Get the Most Out of Your LM CORE Class
Here are 5 tips for getting started and getting the most from your class:
- Get there early and check in with the instructor to get the lowdown on what you can expect.
- Grab a lighter resistance tube to start and really focus on the technique and tempo.
- Pay attention to your instructor and the teaching cues they give for each of the movements.
- Try a few classes to really get a good feel for the movements—don’t stop after one.
- Be receptive to technique cues. You joined a class led by an expert, so utilize their knowledge.
Developing and maintaining a strong, durable core will improve all areas of fitness and movement. Everything really derives from the center, and a stronger center equals a stronger whole.

There is good reason for confusion surrounding what might arguably be one of America’s favorite spreads, topping everything from toast to popcorn to potatoes. The butter-versus-margarine debate has been a hot topic for the last several decades and is still a slippery subject. We have begun to understand the possible dangers of our high saturated fat consumption to our health. However, at the same time we are told that margarines are “artificial,” while butter is the all-natural choice. Which do we choose?
I am often asked what kind of workout program I follow, and my response is always, “I follow a program that gets me faster, stronger, and more athletic.” When people hear this, they assume that I am some kind of athlete and that they won’t be able to work out the way I do since they are not “athletes.” This is a huge misconception that I have noticed throughout the years that I have been working out. What people do not understand is that we are all athletes in our own way, and can actually train like one in order to get faster, stronger, and more athletic.
If you’re trying to lose weight, you’ve probably started exercising, maybe you’re trying a new diet, and maybe you’ve been super consistent for months now, but nothing’s changing. You feel like you’re doing everything right, but you haven’t seen any changes on the scale. How can this be? Weight loss is all about diet and exercise, so why aren’t the pounds just falling off? Research suggests there’s more to weight loss and weight management than diet and exercise alone.
Whether you are starting your first year in college, sending your kids off to school, or are teaching classes this school year, make sure that your nutrition stays at the top of your priority list. It can be easy to get bogged down in your day-to-day routine and quickly lose sight of your goals. Follow these steps to help you stay on track this year.
Growing up and continuing to live in the Midwest, I’ve grown to appreciate the summer months more and more. In fact, in Michigan we joke that there are really only two seasons:
In recent years, carbohydrates have seemingly been blamed for our health problems. Many of us now shun potatoes, rice, and even fruit in fear of the dreaded pounds that could come with eating carbohydrates. While many diets demonize carbohydrates, others preach the benefits of higher-carbohydrate diets. Through all of this confusion, I will try to set the record straight.
Whether you are a seasoned workout veteran or the new face in the gym, there’s no denying that lower-leg pain can be a huge deterrent for exercise (and day-to-day life, for that matter). Some pains are dictated by the range of motion in the ankle. Due to several factors including previous injuries and wear and tear, physiological problems from the various shoes people wear, and the types of exercises people punish their bodies with, we see individuals every day who have a hard time performing some of the more basic exercises such as squats and deadlifting.
