Cardio Tips for Strength Athletes: Keeping Your Engine Running Without Sacrificing Gains

Cardio: The Necessary Evil or My Secret Weapon?
Look, I get it. If you’re anything like me, your happy place is under a barbell. There is something about the silence of the gym at 6:00 AM, the smell of chalk, and the feeling of a heavy deadlift that just makes sense to my brain. For the longest time, I treated cardio like a chore—something I had to “pay” for my sins after a weekend of eating too many street tacos.
But here’s the reality check I had to give myself: your heart is a muscle, too. And if you want to lift heavier, longer, and not feel like you’re going to pass out after a set of ten squats, you need to stop viewing cardiovascular health as the enemy of your gains.
I’m Tessa, and if my golden retriever, Barbell, can go for a three-mile hike in the Rockies without panting, I have no excuse. Let’s talk about how to integrate cardio without turning into a marathon runner or losing all the muscle you’ve worked so hard to build.
Why We Need to Stop Hating on Cardio
I used to think that unless I was lifting, I was wasting my time. I was wrong. Improving your aerobic capacity actually helps you recover between sets. When your heart is more efficient, your blood pumps oxygen to your muscles faster, meaning you can get back to that next set of heavy bench presses with a lower heart rate and more focus.
I’m not saying you need to go out and run a 5K every morning. In fact, if your goals are strictly powerlifting or bodybuilding, excessive steady-state cardio can sometimes interfere with recovery if you aren't fueling properly. But there’s a massive gap between “sedentary” and “ultra-endurance athlete.” We’re aiming for that sweet spot in the middle.
Cardio Tips for Strength Athletes: The “Low and Slow” Approach
If you’re a lifter, skip the soul-crushing hour on the treadmill staring at a blank wall. Instead, lean into what I call “Zone 2” cardio. This is exercise where you can still hold a conversation—or in my case, talk to Barbell about his questionable life choices—without gasping for air.
My favorite way to do this? Incline walking. Set the treadmill to a 3.0 speed and a 10-12% incline. It builds some glute endurance, keeps your heart rate in that optimal fat-burning and aerobic-capacity-building range, and honestly? It’s a great time to catch up on my podcasts.
Make It Functional (Or At Least Less Boring)
I’m a huge fan of “active recovery” cardio. On my rest days, I’m not sitting on the couch (unless Barbell is hogging the spot). I’m out moving. Whether it’s a brisk walk, a bike ride through Denver, or even just doing some light rowing at the gym, the key is consistency, not intensity.
If you struggle to stay motivated, pair your cardio with something you actually enjoy. Does your gym have a sled? Pushing a heavy sled for 10-15 minutes is one of the best ways to get your heart rate up while keeping your movement pattern somewhat aligned with your strength training. It’s hard, it’s humbling, and it’s effective. Just remember: keep it steady. We aren't trying to hit a Puke PR here.
The “Non-Negotiable” Rules for Cardio
If you want to keep your gains, you have to follow a few ground rules:
1. Don’t sacrifice the lift: If you’re doing 45 minutes of cardio before your heavy leg session, you’re doing it wrong. Save the heart-health work for after your lift or on your dedicated rest days. Your central nervous system needs to be fresh for the heavy stuff. 2. Eat for the output: If you’re adding cardio, you’re burning more calories. If your goal is to stay the same weight, you might need to add a bit more fuel to your plate. Don’t starve your body while asking it to work harder. 3. Listen to your joints: If you have bad knees, stay off the pavement. Use the elliptical, the bike, or the rower. There is no “sporting” benefit to running on concrete if it’s going to prevent you from squatting next week. 4. Keep it reasonable: 2-3 sessions a week for 20-30 minutes is usually plenty for most strength athletes. You aren't training for the Olympics; you’re training to be a human who can carry all the grocery bags in one trip.
Strength is the Whole Personality
At the end of the day, being strong isn’t just about the number on the bar. It’s about being capable in every facet of your life. It’s about having a heart that can handle the stress of a heavy set and a body that recovers quickly so you can show up again the next day.
I’ve found that since I started taking my cardio seriously—even if it’s just dragging Barbell out for an extra-long walk—my training has actually improved. I’m less gassed, I’m more focused, and I feel like a more complete athlete.
Don’t overthink it. Put on a good playlist, find a movement that doesn’t make you want to scream, and get that heart moving. Your future self (and your heart) will thank you.
