WHOOP Advanced Labs integrates testosterone, estradiol, Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), TSH (thyroid-stimulating hormone), cortisol, and more from your lab tests. Low energy, mood swings, and poor recovery can all signal hormone imbalances. Tests through WHOOP Advanced Labs measure key metabolic markers like glucose, insulin, Hemoglobin A1c (HbA1c), and HOMA-IR to show how efficiently your body processes and regulates energy. Biomarkers are measurable indicators of how your body’s systems are functioning, things like glucose, vitamin D, or cortisol levels. It’s a smarter, more informed way to support your long-term health. Unlike traditional lab tests that leave you with a report and no next steps, WHOOP Advanced Labs delivers a deeper layer of insight, adding your results to your continuous data. The most recent update to Journal allows the app to get way more granular and specific about your behaviors. Whoop previously did a "User Input Survey" to collect information like how you felt when you woke up or how much screen time you had. Included is the strap, charging clip and charging cord. The WHOOP "secret sauce" comes from our ability to learn from all the data we collect from you and use it to personalize our algorithms. You can update your sex, height, and weight by hitting the pencil icon in the upper right corner of the profile page on your mobile application. This phenomenon seems to be primarily driven by differences in muscle mass (those with greater muscle mass burn more calories than do those with less muscle mass) and differences in testosterone levels (testosterone increases basal metabolic rate).

The WHOOP app is available in English, French, German, Italian, and Spanish. Healthspan refers to the number of years someone lives in good health, free from chronic disease, functional decline, and preventable limitations. The Whoop correctly evaluated my weekday 5-mile training runs at around 14 on the strain scale — which is on the border of moderate to high intensity. Not only is it less accurate for heart rate tracking, but many people also find it uncomfortable for sleep. The only things the Whoop tracks are cardiovascular strain, recovery, and sleep. WHOOP Advanced Labs testing gives you 65 biomarkers per panel, a clinician-reviewed report, and an action plan in the app. With the option to retest over time, it’s a clearer, smarter way to understand and support your long-term health. Each WHOOP Advanced Labs test looks at 65 biomarkers alongside your 24/7 WHOOP data. WHOOP Advanced Labs is an add-on to your membership that combines clinical lab testing with your 24/7 WHOOP data. Together with 100,000+ daily data points from WHOOP, you get the most actionable and complete view of your health. WHOOP Advanced Labs measures 65 biomarkers, carefully chosen for their impact on your overall health and Healthspan. Identify overlooked biomarkers — like Apolipoprotein (ApoB) —that routine panels may miss, but can point to significant health risks. Participants must be 18 or older and cannot be pregnant at the time of testing. Tests through WHOOP Advanced Labs check biomarkers like vitamin D, ferritin, calcium, and iron saturation to identify gaps. Sleep affects nearly every system in your body from mood and focus, to hormone regulation and inflammation. Chronic inflammation is linked to fatigue, poor recovery, and long-term disease risk. First, it’s so easy to lose, replacing it costs $49, and there’s no other way of charging the tracker. But while I appreciate how clever it is, there are a ton of drawbacks. It’s great for people who hate that one- to two-hour gap in data when charging their trackers. The pack slides onto the tracker itself, and you can actually charge the device while you’re wearing it. Finally, the recovery function basically lets you know how your body is doing. Whoop will take all those activities into account to calculate your total day strain. There were some workouts where I felt the strain score was accurate, and somewhere I was like, "You’ve got to be kidding, I definitely worked out hard today." Then, it figures out how much time you spent in those zones and BOOM you get a strain score.
