Stop Chasing Miles: The Smart Approach to Cardio for Every Athlete

Cardio Isn't a Punishment
I’ve spent a lot of time in gyms—from the high-intensity D1 locker rooms at A&M to the garage setups I help my remote clients build today. If there is one thing I hear more than anything else, it’s this: “Marcus, I hate cardio, but I need to lose weight, so I guess I’ll go run for an hour.”
Stop. Just stop. If you look at cardio as a punishment for the pizza you ate on Friday or a necessary evil to burn calories, you’re never going to stick with it. After I tore my ACL, I had to completely reframe my relationship with movement. My identity wasn’t the guy who could out-sprint everyone on the court anymore. I had to learn how to move in a way that preserved my body while still hitting my goals. That shift changed my life, and it’s the exact philosophy I use with every client I coach.
Cardio is a tool, not a penance. It’s about building a bigger engine so you can live a better life. Let’s clean up your approach.
Rethinking Your Intensity Zones
Most people make the mistake of training in the “gray zone.” You know what I’m talking about—you’re working hard enough to be uncomfortable, but not hard enough to actually trigger significant conditioning adaptations. You’re just grinding yourself down.
I want you to Polarize your training. Think of it like this: 80% of your cardio should be what I call conversational. If you’re walking, cycling, or hitting the elliptical, you should be able to hold a conversation without gasping for air. This is your Zone 2 training. It builds your aerobic base, improves your heart health, and helps with recovery.
Then, for that remaining 20%, you go to the dark place. I’m talking high-intensity interval training (HIIT) or short, sharp bursts of effort that leave you needing a minute to catch your breath. My golden retriever, Kobe, has more intensity in his morning zoomies than some people have in their entire weekly workout. Don't be that person. If you’re going to work hard, actually work hard. If you’re going to go easy, keep it easy.
The “Non-Exercise” Secret
If you want to lose body fat, stop obsessing over the 45 minutes you spend on the treadmill and start looking at the other 23 hours of your day. This is where most of my clients see the biggest transformation.
I call it NEAT (Non-Exercise Activity Thermogenesis). It’s the movement you do outside of the gym. If you sit at a desk for 10 hours and then do a 30-minute “hard” workout, you’re still largely sedentary. I tell my clients to aim for a daily step goal—start with 8,000, move to 10,000. It sounds basic, but it’s the most underrated “cardio” tool in the arsenal. It doesn't spike your cortisol like excessive, chronic cardio, and it keeps your joints happy. Trust me, your knees will thank you later.
Mix Up Your Modality
Back in college, I lived on the court. After the ACL injury, I had to find other ways to condition. I started swimming, rowing, and using the air bike. The variety kept me sane. If your joints are feeling beat up—maybe you’re a heavy lifter—stop running on concrete. Take it to the rowing machine or the swimming pool. Your heart doesn’t know the difference between a jog and a hard session on the rower; it only knows the heart rate you’re hitting. Protect your longevity. I want you to be training well into your 60s, not burning out by your 40s because you ran your joints into the ground.
Actionable Steps for This Week
1. Audit your current routine: Are you stuck in that ‘gray zone’ where you’re always tired but never progressing? Pick one day this week to go significantly slower and one day to go significantly faster. 2. The 10-Minute Finisher: If you’re short on time, don’t skip cardio. Do a 10-minute EMOM (Every Minute on the Minute) of kettlebell swings or air bike sprints. It’s efficient, effective, and gets the job done. 3. Get your steps in: Download a tracker, set a goal, and hit it. Rain or shine. Take the stairs. Park further away at the grocery store. It adds up.
Final Thoughts
Remember, your body is the only place you have to live. We aren’t trying to break it; we’re trying to build it. My journey with my knee taught me that patience is actually the fastest way to get results. You don't need to run a marathon tomorrow to see progress. You just need to show up and be smarter about how you move.
