Oura is adding 'Cardio Effort' and VO2 max to its ring workout tracking, giving members a clearer read on workout strain and long-term fitness. The pair moves tracking beyond exercise minutes and heart-rate zones by scoring cardiovascular load and estimating aerobic capacity, or how well the body uses oxygen during exercise.
Cardio Effort weights intensity alongside duration, so a short, hard session can match a longer, easier one. The score rolls into a weekly total built around each member's baseline. It is rolling out on 'Oura Ring Gen3' and later models. VO2 max enters 'Oura Labs' for members with Gen3 and newer rings. After five qualifying GPS-based activities, it produces an initial estimate.
Passive VO2 max estimates turn a lab-linked fitness marker into everyday ring data. Cardio Effort on Gen3 hardware also makes workout review more comparative, which sharpens Oura's case as smart-ring competition rises.

What Makes This Trend Stand Out
- Passive Fitness Biomarkers
- Wearable devices are translating clinical metrics like VO2 max into continuous consumer data, creating openings for health platforms that blend everyday tracking with preventative wellness insights.
- Cardio Load Scoring
- Personalized workout strain scores are making exercise measurement more comparative and context-aware, revealing potential for coaching tools that adapt to individual baselines instead of generic activity targets.
- Smart Ring Competition
- Compact wearables are expanding beyond sleep and recovery into advanced fitness analytics, intensifying demand for differentiated sensors, algorithms, and subscription-based health features.
Sectors Adopting This
- Wearable Technology
- The category is shifting toward discreet, always-on devices that deliver deeper physiological intelligence, supporting new product ecosystems around rings, patches, and sensor-enabled accessories.
- Digital Health
- Consumer access to fitness and cardiovascular indicators is blurring the line between wellness tracking and preventive care, opening space for platforms that connect self-monitoring with professional health guidance.
- Fitness Technology
- Exercise platforms are evolving from counting workouts to interpreting intensity, recovery, and aerobic capacity, creating opportunities for more personalized training feedback across apps and connected devices.
