Cardio for Powerlifters: Yes, You Should Be Doing It. Here’s How.

"Cardio kills gains." It's a phrase echoed in powerlifting gyms for decades. The fear is that any form of cardiovascular exercise will eat away at your hard-earned muscle and strength. But this is an outdated and simplistic view. When programmed intelligently, cardio for powerlifters is not a gains-killer; it's a performance-enhancer. A strong heart and good conditioning build a more resilient, healthier, and ultimately stronger athlete. This guide will explain why you need cardio and how to incorporate it without hurting your strength.

The Benefits of Cardio for Strength Athletes

Building a solid base of cardiovascular fitness, often called General Physical Preparedness (GPP), has several profound benefits for a powerlifter:

1. Improved Work Capacity: This is the big one. Good conditioning allows you to handle higher training volumes with less fatigue. You'll be able to recover faster between heavy sets, meaning you can perform each set with higher quality and intensity.

2. Enhanced Recovery: Cardio increases blood flow throughout the body. This helps deliver nutrients to your muscles and clear out metabolic waste products generated during heavy training, which can speed up the recovery process between workouts.

3. Cardiovascular Health: Being strong is fantastic, but being healthy is paramount. Lifting heavy weights can temporarily spike blood pressure. Regular cardio helps maintain a healthy heart, manage blood pressure, and improve overall cardiovascular health markers, as recommended by leading health organizations like the American Heart Association.

4. Better Body Composition: Cardio is a tool that helps you expend more calories, making it easier to manage body fat during a bulking cycle or to aid in fat loss during a cutting phase.

The "Interference Effect": Fact vs. Fiction

The fear of cardio comes from a concept called the "interference effect," which suggests that the cellular signaling pathways for endurance (AMPK) and strength (mTOR) can conflict with each other. While this effect is real, its impact is often greatly exaggerated.

A scientific review from Stronger by Science concluded that as long as cardio is programmed intelligently, its negative impact on strength development is minimal to non-existent for most lifters. The key is in the how and when.

The Best Types of Cardio for Powerlifters

To minimize interference and maximize benefits, choose your cardio wisely.

• Low-Intensity Steady State (LISS):

  • What it is: Maintaining a low, consistent heart rate for an extended period.

  • Examples: Brisk walking on an incline treadmill, light cycling, using an elliptical or rower.

  • Why it's great: LISS has very little impact on recovery and doesn't create much muscular damage. It's excellent for improving cardiovascular health and aiding recovery.

• High-Intensity Conditioning (HIC):

  • What it is: Short bursts of all-out effort followed by rest.

  • Examples: Prowler pushes, sled drags, farmer's walks, battle ropes, kettlebell swings.

  • Why it's great: These movements are concentric-dominant (they lack a muscle-damaging eccentric phase), build incredible work capacity, and have a high carryover to strength. This is GPP in its purest form, as popularized by training systems like Westside Barbell.

How to Program Cardio Intelligently

• Timing is Everything: To avoid fatigue affecting your main lifts, perform cardio after your lifting session or on a separate, non-lifting day. Never perform intense cardio immediately before a heavy squat or deadlift session.

• Frequency and Duration: Start small. Aim for 2-3 sessions per week for 20-30 minutes. You don't need to spend hours on a treadmill.

• Match the Type to Your Goal:

  • For general health and recovery: LISS is your best friend.

  • For building insane work capacity: HIC with tools like a prowler or sled is ideal.

It's time to retire the myth that cardio kills gains. For the modern powerlifter, smart cardiovascular training is an essential tool. It builds your engine, enhances your recovery, improves your health, and ultimately allows you to train harder and more effectively. Stop thinking of cardio as a separate activity, and start seeing it as a vital part of what makes you a more resilient and powerful athlete.
