Recovery Nutrition: The Hidden Driver of Competitive Performance
As athletes, we often focus on how hard we can train, stacking sets, grinding through metcons, and pushing our limits every session. But what happens ...
When you’re gassed halfway through a long metcon, it’s easy to assume aerobic capacity is the issue. But before you simply add “more cardio,” take a step back and dig deeper.
By isolating your true limiter and using the right tests, you can determine whether it’s aerobic capacity, muscular endurance, movement inefficiency—or something else entirely—affecting your performance.
In this episode, we dive into how to identify your real limiter and, if it is aerobic capacity, what to do about it.
1️⃣ Aerobic Capacity is More than Just Cardio
It’s your ability to maintain high heart rate and respiration for an extended period—typically 15–25 minutes in CrossFit, or up to 90 minutes in something like HYROX.
But poor performance in long metcons doesn’t automatically mean you need more aerobic training—it could be: local muscular fatigue, poor movement efficiency, or skill bottlenecks.
2️⃣ How to Identify Your True Limiter
Not all weaknesses are the same. CrossFit workouts aren’t the best place to test aerobic capacity because other factors—like muscular fatigue or technical breakdowns—can interfere.
In the episode, we walk through specific test types to help you pinpoint what’s really limiting you.
3️⃣ You Can’t Just “Suffer” Your Way to Better Aerobic Capacity
Grinding through more metcons won’t cut it. You need dedicated, structured aerobic work to develop your cardiovascular system. We break down exactly how to do that, and why isolating aerobic work with cyclical modalities (like running, rowing, biking) matters.
4️⃣CrossFit Athletes Need Sport-Specific Testing
Generic cardio tests won’t cut it. You need aerobic tests that reflect the demands of the sport.
Enter the TTT Sh!t Sandwich Test:
For Time:
1-mile run Echo
Bike: 150 cals (men) / 120 cals (women)
1-mile run
Why it works:
It balances running and machines, mimics the fatigue curve of real CrossFit events, and gives you insight into your aerobic capacity without muscular fatigue clouding the result.
