How To Attack Your CrossFit® Cardio Training

Written By Charleh Knighton  |  Conditioning 

It's time to get those engines moving and attack your cardio training. Cardio is a staple for off-peak season training, and as athletes, our goal is to increase capability and improve our scores in workouts. Effectively attacking your cardio training requires a strategic approach that balances intensity, variety, and recovery.

In this guide, we'll show you how to improve your cardio performance and start tackling some cardio workouts. If you want to jump straight to the free cardio workouts, scroll half way down the page!

Here are the key steps to optimize your cardio training:

1. Set Clear Goals

Determine what you want to achieve with your cardio training. Are you aiming to improve your overall endurance, increase your speed, or enhance your recovery times between high-intensity efforts? Clear goals will help you tailor your training program effectively.

2. Incorporate Variety

CrossFit® is known for its constantly varied workouts, and your cardio training should be no different. Include different types of cardio workouts such as running, rowing, cycling, swimming, and jump rope. In all seriousness, this variety will prevent total boredom. Like, no wants to run the same 10km route, 3-4 times a week, 52 weeks a year.

Here are two variations you can use to mix up your cardio workouts:

High-Intensity Interval Training (HIIT)

HIIT is a staple in CrossFit® due to its efficiency and effectiveness. Incorporate short bursts of intense activity followed by periods of rest or low-intensity exercise. For example, alternate between 30 seconds of all-out effort on the rower and 30 seconds of easy rowing for a total of 10-15 minutes.

Steady-State Cardio

While HIIT style training is crucial, don't neglect steady-state cardio. Long, slower efforts at a moderate intensity can help build your aerobic base and improve overall endurance. Aim for sessions that last 30-60 minutes at a conversational pace.

3. Benchmark Workouts

Regularly include CrossFit® benchmark workouts that test your cardiovascular capacity. Workouts like "Murph," "Helen," or "Fight Gone Bad" are excellent for measuring progress and setting performance goals.

4. Skill Work

Some cardio activities require specific skills, such as efficient rowing or double-unders. Dedicate time to improving these skills, as they can make your cardio workouts more effective and less taxing.

5. Monitor Intensity

Use tools like heart rate monitors or perceived exertion scales to ensure you’re training at the right intensity. These tools help balance your training load and prevent overtraining.

The worst thing you can do is go from zero to 100. It takes time for your body to adapt to new training stimuli or volume. Be kind and patient with yourself.

6. Progressive Overload

Following on from the previous point, gradually increase the intensity, duration, or frequency of your cardio sessions. This principle of progressive overload will help you continually improve your cardio fitness without risking injury.

7. Recovery and Nutrition

Cardio training can be demanding, so prioritize recovery with adequate sleep, hydration, and nutrition. Incorporate active recovery sessions like light yoga, or stretching to keep your body in optimal condition. If you're not sure where to start, continue reading here and contact a professional.

8. Consistency

Consistency is key to improving cardio fitness. Aim to include cardio sessions in your training program 3-5 times per week, depending on your goals and overall training volume. Again, if you're not sure where to start, continue reading here and contact a WODprep coach for more information.

Is CrossFit® a Good Cardio Workout? 

Absolutely! CrossFit® incorporates high-intensity functional movements that elevate your heart rate and build cardio endurance. The varied and intense nature of CrossFit® workouts makes them an excellent cardio option.

What are the 3 Main Components of CrossFit® Training?

CrossFit® training revolves around three main components:

  1. Metabolic Conditioning (Cardio) - Improving cardio and respiratory endurance.
  2. Gymnastics - Enhancing body control and strength through movements like pull-ups and handstands.
  3. Weightlifting - Building power and strength through Olympic lifts and other weight-based exercises.

Is CrossFit® Better Than HIIT?

CrossFit® and HIIT both offer intense workouts that improve cardio fitness. CrossFit®, however, incorporates a broader range of movements, including weightlifting and gymnastics, providing a more comprehensive approach to fitness.

Is 20 Minutes of CrossFit® Enough?

Yes, 20 minutes of a well-structured CrossFit® workout can be highly effective. The intensity and variety packed into short CrossFit® sessions can significantly improve fitness levels, making every minute count.
