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!

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.
Nowadays, it seems that many people are trying to find that next great gadget to help put them over the top. Whether it’s the fitness world, life at home, or the day-to-day grind at the office, people seem to be peddling some kind of shortcut or cheat code to help aid performance in some way, shape, or form. I know I can’t go a day without scrolling through Instagram and seeing an ad for some new, expensive toy guaranteed to solve whatever problem I seem to be having that day.

Getting old sucks. That’s right, I said it: getting old sucks. I might be the only one in the fitness world to say it, but it does. I know I’m supposed to be positive about the inevitable passing of time and what each of us face in our journeys—and I’m positive it is not fun at all. No matter whether you are turning 20 or 70, we are all getting older and it is getting old! If you can’t tell by now, I am a bit grumpy about some of the aspects that each passing birthday has in store; and much like Ebenezer Scrooge, I say, “Bah humbug” to it all!
It’s finally that time of year again—time to hit the links and chase a little ball all over a well-manicured green space with the hopes of golf immortality. If you are like me, you have a love/hate relationship with the sport of golf, but I look forward to my weekly round with friends to take on challenging courses and ultimately myself.
So often in life people like to look at things as win or lose. But what if you switched your perspective to thinking of making progress by winning each day? With this simple shift, your days can be filled with more positivity and success instead of the typical mindset of losing or not being good enough.
The peripheral pollution surrounding what fitness and wellness should look like and how you get there is near epidemic status. The topic of high-intensity training receives the majority of the attention, with using Olympic lifts for conditioning a close second. And oh, what is “Insta-worthy” is atop the pollution charts as well. Okay, so that last one was a personal gripe more than based on empirical data. No matter; there are so many messages out there, many of them incorrect and downright unsafe, that it is hard to wade through the muck to get to the clear and beneficial information.
I celebrated my 40th birthday almost a year ago but postponed writing the “I’m 40 now” blog until now, mainly because it is a bit played out. But more importantly, I wanted to see what this 40 thing was all about before writing about it.
Check your expectations/mindset. Although it can be hard to handle at times (believe me), physical abilities are going to change and it is important to evaluate and adjust your expectations. This will help when you are faced with a physical challenge that you might have formerly handled pretty easily, to determine whether you should attempt it or live to fight another day. Your mindset is your story; now it’s just the next chapter. Negative self-talk about what you used to be able to do will not help in moving forward positively. I have found it helpful to manage the minimums and find that new normal. This will keep you safe both physically and mentally.
Fitness trends come and go, but heart-rate training is something that has been around for a long time; and due to its validity, I have a feeling it will not be leaving anytime soon. In fact, some places base their entire programming around your heart rate. And knowing your heart-rate training zone is actually a very useful tool for anyone—from the marathon runner to the three-times-a-week boot camp attendee!
