Common Questions
What is the best WOD format for building cardio?
Long AMRAPs (20–30 minutes), moderate-intensity EMOMs, and For Time workouts in the 15–25 minute range build aerobic base most effectively. The key is sustained output at 70–80% max heart rate for extended periods.
How do I know if a workout is developing my cardio?
Track your resting heart rate over weeks (it should decrease) and your performance on benchmark workouts (times should improve). Feeling like you can work longer before getting breathless is the most immediate indicator.
What is VO2 max and how do WODs improve it?
VO2 max is your body's maximum oxygen processing capacity — the gold standard of cardiovascular fitness. High-intensity training pushes your heart rate to 90-95% of maximum, which provides the strongest stimulus for VO2 max improvement. WODs in the 10–20 minute intense range are most effective.
How long before I see cardio improvement from WODs?
Most athletes notice improved breathing efficiency in 2–3 weeks. Measurable VO2 max improvements take 4–8 weeks of consistent training. Long-term aerobic base building (for events like HYROX) requires 12–16 weeks of progressive training.
