Train what matters for the Open/Quals
Testing reveals whether your limiter is VO₂ capacity, threshold, or efficiency so you can program intervals and zone work with precision.
Calibrate your devices & ergs
Lab zones (HR/power) beat wearable estimates, making your Garmin/Apple and rower/Assault Bike guidance match your physiology.
Recover quicker between efforts
Better aerobic capacity improves repeatability and clears fatigue faster, key for multi-round WODs.
Build a bigger engine fast
VO₂-guided intervals raise aerobic capacity more than steady work, and HIFT/CrossFit-style training is shown to improve VO₂max.
Pace without redlining
Ventilatory thresholds give clear caps for AMRAPs/EMOMs and longer metcons, reducing blow-ups and HR drift.
