You can bench 225 but you're out of breath walking up two flights of stairs. You skip cardio because "it kills gains." Your heart rate hits 160 carrying groceries. We need to talk.
Your cardiovascular system is the engine that runs everything else. If the engine sucks, nothing else works well. Not your lifting, not your recovery, not your daily life.
This myth needs to die. Running a marathon the morning of your heavy squat day? Yeah, that's going to interfere. Going for a 20-minute jog on your off days? That improves your recovery, your work capacity, and your ability to handle volume in the gym.
The strongest powerlifters I've known all had a cardio base. They could warm up without getting winded. They could handle higher rep sets without their heart rate redlining. They recovered faster between sets. Cardio doesn't fight against strength. It supports it.
Most people quit running because they go out and try to run a mile at full speed on day one. Their lungs burn, their shins hurt, and they decide running isn't for them. That's not running's fault. That's your ego's fault.
Start with walk-run intervals. Run for 60 seconds, walk for 90 seconds. Repeat for 20 minutes. That's it. If 60 seconds of running is too much, run for 30 seconds. There's no minimum entry point. Just move faster than walking for short bursts and build from there.
Your aerobic base is your body's ability to use oxygen efficiently. When it's strong, everything is easier. Your resting heart rate drops. You recover faster between sets. You sleep better. You have more energy throughout the day. You're not gasping after playing with your kids for five minutes.
Building it is boring. It's slow, easy cardio where you can hold a conversation. Zone 2, if you want to get technical. It doesn't feel like a workout. That's the point. You're training your cardiovascular system, not trying to set a personal record every time you lace up.
Hate running? Fine. Bike. Swim. Use the elliptical. Row. Walk uphill on a treadmill. The movement pattern doesn't matter as much as getting your heart rate into that easy aerobic zone for 20-30 minutes, three or four times a week.
I ran a marathon in my 30s. I also went through years where I only biked and walked. Both built a solid cardio base. Pick the one you'll actually do consistently.
Two or three 20-minute sessions per week of easy cardio. That's the floor. Walk fast, jog slow, bike at a pace where you could talk to someone. It doesn't need to be dramatic. It doesn't need to be Instagram-worthy. It just needs to happen.
You're going to feel weird the first time you jog and it's actually easy. That means it's working. Your body adapted. Now go a little longer or a little faster. That's progressive overload for your heart. So run, dumbass.
