How we test wellness gear

• Quantified protocols: we follow consistent multi-week routines (4-6 weeks minimum) to evaluate cumulative effects, not single-session impressions.
• Sensor accuracy: heart rate, SpO2, and sleep trackers are validated against medical-grade reference devices.
• Comfort during real workouts: tested by working personal trainers across CrossFit, running, cycling, and strength sessions.
• No magic claims: if the peer-reviewed evidence is thin, we say so — even when the marketing is loud.
