For whatever reason, there seems to be this notion in the fitness industry that if the workout doesn’t leave you on the ground gasping for air, it really wasn’t a good one. Or maybe that you didn’t work hard enough because you didn’t go running to the nearest trash can by the end. This could not be further from the truth; but unfortunately this way of thinking still seems to run rampant.
Not Every Workout Has to Be a Gut-Buster
One of my favorite quotes when it comes to strength and conditioning comes from Yuri Verkhoshansky, Russian professor, coach, and author who is credited as being the father of plyometrics. He suggests that “any idiot can make another idiot tired.” Now, I’m not calling anyone out. But this brings up a fantastic and often forgotten premise: that we should not judge the quality of a training session simply by how exhausted we feel.
Yes, we should challenge ourselves. Yes, there should be times when a workout feels more difficult. But here’s the key: not every workout should feel like a gut-busting knock-down, drag-out fight to the finish. If it does, it might be time to reevaluate.
A Quick Exercise Physiology Lesson: The Aerobic System
Our bodies rely on three energy systems to get us through everything from a tough workout session to washing the dishes, as well as basic organ function around the clock. They are all operating in some capacity all of the time, just in varying degrees based on the activity we’re doing. It’s not like a light switch, just on/off. Here are our players:
- The ATP-PCr or phosphagen system (immediate)
- The anaerobic or lactic system (short term; remember glycolysis?)
- The aerobic system (long term)
Now, this isn’t intended to be a full-blown Bill Nye-esque science lesson. But I do want to focus on one of those energy systems for just a moment because it plays a massive role in how we are able to recover from task to task. And that is the aerobic system. It has the capacity to produce a great deal of energy, ATP—our body’s form of energy currency. The only problem is that is takes a little while longer to do compared to the other two. As a result, the aerobic system is responsible for replenishing and producing energy during rest periods or downtime between bouts of high-intensity exercise.
Much like any facet of fitness, this system can be trained directly. It typically comes in the form of slightly lower-intensity exercise (examples to come in a future post). So, while the exercise session might not feel like a back-breaker, the benefits that arise from it can come back twofold when looking at future training sessions. Essentially, what you’re doing when you are working on bolstering your aerobic system is building a bigger, more efficient engine.
Reap the Benefits of Faster Recovery
So, those high-intensity classes you take a couple times per week? Think about being able to sustain the same power and strength from round to round because you can recover more effectively during your rest periods. Or maybe you like to hop under the bar for some strength training in the form of squat or bench press. Well imagine being able to hit more of those heavy singles because you recover more proficiently between sets. That’s when the aerobic system really kicks into high gear: during rest. Yes, it is always contributing to some degree when it comes to ATP production (remember energy currency?). But its benefits really come to light during the downtime.
Building your fitness profile really requires a 360-degree approach. Some sessions may focus on strength. Some sessions may focus on high-intensity training. And some should take the time to address the aerobic system. Not only do they provide the body some much-needed recovery time; these sessions can also allow you to get more out of those strength and high-intensity workouts as well.
Next time, I’ll cover specific examples of how you can train your aerobic system. Until then, stay strong, my friends!

It’s safe to say that 2020 has been one a heck of a year (and it’s barely half over!)—the good, the bad, the ugly. At times, it’s felt as if an entire decade has passed. No matter how you slice it, the fact that we’ve experienced something as novel as a global pandemic still feels weird to say, think about, and sometimes fully appreciate. It has been a tumultuous time outside of COVID-19 as well, and every person has had a unique experience, a unique perception, and unique challenges along the way.
The glorious return to summer is upon us, and if you are like me, you will be spending as much time as possible soaking up sunshine as you take your leisure outdoors, take up hobbies in the yard and garden, and engage in group fitness bootcamp classes in the park. The sunshine feels good and has many benefits, including mood enhancement, vitamin D production, and even treatment for a number of skin conditions such as psoriasis and acne. There are, however, some dangers associated with extended sun exposure that can be limited with the use of sunscreen, most notably skin cancer.
We all know that physical fitness and wellness are prerequisites for a productive and healthy life. Exercise is good not only for the body, but for the mind as well. We want to ensure a future full of great experiences. For one population, our children, participating in physical activity may be becoming more and more challenging, whether it be from lack of interest, lack of support, or lack of funding for programs in their community. One area in which this population excels, however, is technology. Without a doubt, smartphone technology is a part of our current culture and most likely will be for a long time. For some older people, this might be a newer concept. At the moment, though, ensuring the future of physical fitness for the next generation will need to coexist with technology.
There seems to be an expectation that women are supposed to do it all and not complain. That women are supposed to be wives and mothers, work full time, juggle friendships, have a social life, have time for themselves, so on. Society is ever changing, and we are supposed to keep up with it. Let’s rewind some years ago where most women stayed at home with their children, and taking care of their household was their only responsibility.

Do you remember the last time you went on an extended vacation, came back home, jumped into the gym and your favorite class and thought you could pick right back up where you left off? You might remember feeling like you were not going to make it through the class and were so sore for days on end. And that was just after a vacation consisting of a long rest, relaxation, and food freedom. Just think what you may encounter once you return to your favorite class or training group after two to three months of quarantine.
Today, the realities of the human body immediately after giving birth are less mysterious than ever, a development some attribute to a changing climate around motherhood. In the past women felt like they couldn’t talk about the after-effects of having a baby, let alone caring for other children at the same time.
A few years ago, I made it my New Year’s Resolution to completely cut out animal products from my diet. I had played around with a couple variations of diets for a few years in college while competing in a Division 1 rowing program—cutting out all red meat, processed meats, and chicken, and only eating fish. Essentially the only things left were the eggs, milk, and cheese. I had been hesitant because cheese was my absolute favorite thing to add to every meal. I dreamed about doing a cheese and wine tour of Europe one day—I was really in love with cheese.
Picture this: You’re sitting in the car, in stop-and-go traffic. Your mood is just shot and all you want to do is get home. Now try this: Turn up the volume on your radio and let the music take over your soul!
