But for now, the only people who should give a whoop about Whoop are athletes. Ideally, a lot of what it’s doing now will eventually make its way back into more mainstream devices. The data is solid if you care about performing at the highest possible level at a cardio-intensive sport. Instead, the heart rate monitor is constantly on and tracking your resting heart rate (rhr) as well as how your heart rate climbs throughout the day. The Whoop Strap 3.0 is designed for athletes looking to get a deeper look into their sleep and health metrics to determine if they can engage in training. There’s something to be said for a small device on your wrist that can tell you if you’re getting enough sleep, taking enough vitamins, and avoiding overtraining. Check with WHOOP if you are a member (I think it’s USA only) or your doctor to start optimising your health today! During his two-and-a-half years there he wrote news stories for the website and features for the magazine, while he also interviewed names such as Les Ferdinand, Ally McCoist, Jamie Redknapp and Antonio Rudiger, among many others. He has his own nutritionist to help him achieve an optimum body composition. With a clear focus on consistency, Ronaldo rarely indulges in food, using it more as fuel for his body to help him perform in matches. He believes that for every hour of physical exertion you need to spend the same amount of time purposefully recovering. The Portuguese star's training doesn't stop there, though. I have learned from time and with my experience, and adjust year by year.' Together, we got a good sense of what it’s like to lean on the Whoop for the info you need to maximize your training efforts. But, it does provide some useful tools if you really want to dive into how your body responds to training. WHOOP connects this to your strain and VO₂ Max, helping you balance fluids and protein for better performance. High ratios can mean you’re dehydrated from intense training. WHOOP pairs haemoglobin with strain data to show when low oxygen might hold you back. WHOOP ties estradiol to your sleep and weight trends, helping you see how hormonal shifts impact your daily performance. This hormone drives muscle growth, recovery, and sexual health in both men and women. BOSTON, MA — September 30, 2025 — WHOOP, the human performance company, today announced the launch of WHOOP Advanced Labs, a groundbreaking new feature that combines blood testing with continuous wearable data to deliver a complete picture of health. WHOOP measures how your body responds to strain with metrics like VO₂ Max and HRV, but WHOOP Advanced Labs goes deeper — using test results measuring fitness-related biomarkers like free testosterone, BUN/creatinine, and ferritin. To calculate your recovery, the Whoop looks at your sleep quality as well as your heart rate variability, respiratory rate and resting heart rate. WHOOP tracks sleep quality, REM/deep sleep, and HRV, while WHOOP Advanced Labs adds hormonal and inflammatory biomarkers like cortisol, insulin, and hs-CRP. WHOOP Advanced Labs tracks test results for key lipid markers like total cholesterol, HDL, LDL, ApoB, triglycerides, and lipoprotein(a) measure lipid biomarkers that research has linked with cardiovascular health. WHOOP monitors stress and recovery signals, while WHOOP Advanced Labs looks at biomarkers like high-sensitivity C-Reactive Protein (hs-CRP), homocysteine, and white blood cell ratios to help flag systemic inflammation. These insights help you understand how your body handles muscle stress and protein metabolism so you can train smarter and recover faster. When paired with HRV, RHR, and sleep tracking, you can get a better picture of how your endocrine system may play a role in how your body performs and recovers. It connects your lab results to your real-world habits, and turns your data into daily coaching that helps you make meaningful progress over time. Understand how your habits can affect hormonal health, metabolic performance, inflammation, and more.
