The waterproof PowerPack is particularly useful for endurance athletes who want to charge on the go without removing their device. During testing, one reviewer observed only 38% battery drain after six full days of use, suggesting the actual battery life could exceed 16 days under normal conditions.
Sensor Technology
WHOOP 5.0’s upgraded sensors collect data continuously, capturing information every second with 26 data points per second. This allows for more accurate tracking of:
- Heart rate and heart rate variability (HRV)
- Respiratory rate
- Blood oxygen levels (SpO₂)
- Skin temperature
- Movement and activity levels
The improved sensors aim to deliver what WHOOP claims is “~99% accuracy” for heart rate monitoring, addressing a common criticism of previous generations.
Key Features and Metrics
Core WHOOP Metrics
WHOOP continues to focus on its three signature metrics:
- Strain (0-21 scale) – Quantifies cardiovascular load and muscular exertion throughout the day
- Recovery (0-100%) – Morning readiness score based on HRV, resting heart rate, sleep performance, and respiratory rate
- Sleep – Tracks sleep stages, efficiency, disturbances, and overall quality
These metrics remain at the heart of the WHOOP experience, prominently displayed in the redesigned app’s Home Screen with clear dials and detailed explanations.
New Health Monitoring Features
WHOOP 5.0 introduces several groundbreaking features:
Healthspan & WHOOP Age
The new Healthspan feature calculates your physiological age (“WHOOP Age”) based on nine biomarkers including sleep, steps, HRV, and VO₂ max. Developed in partnership with the Buck Institute for Research on Aging, this feature tracks your “pace of aging” and provides actionable recommendations to improve longevity.
For athletes concerned about the long-term impacts of intense training, this feature offers valuable insights into whether their training regimen is supporting or potentially harming long-term health.
Stress Monitoring
Available in the Peak and Life subscription tiers, real-time stress monitoring uses multiple biometrics to identify high-stress periods throughout the day. This feature helps users understand how stress affects recovery and performance, allowing for better stress management strategies.
Step Counter & Activity Detection
A long-requested feature, step tracking is now standard across all subscription tiers. WHOOP has also improved its activity auto-detection capabilities, making it easier to track workouts without manual input.
Women’s Hormonal Insights
WHOOP 5.0 provides personalized insights into how hormonal fluctuations affect recovery, sleep, and training capacity. This feature is available across all subscription tiers and helps female athletes optimize training based on their menstrual cycle.
Weekly Performance Assessment
The app delivers a Weekly Performance Assessment (WPA) every Monday, comparing the previous week’s strain-vs-recovery balance and sleep consistency. This coaching report breaks down weekly strain by activities compared to recent averages, helping users identify trends and make adjustments.
WHOOP MG: Medical-Grade Monitoring
The WHOOP MG represents the company’s first foray into medical-grade health monitoring, adding two significant health features:
On-Demand ECG
The FDA-cleared ECG feature allows users to capture a medical-grade electrocardiogram by simply placing a finger on the device for 30 seconds. This can detect irregular heart rhythms, including atrial fibrillation (AFib), providing peace of mind for athletes concerned about cardiac health.
Blood Pressure Insights
WHOOP MG offers daily blood pressure estimates after initial calibration with a standard blood pressure cuff. This feature helps users monitor trends in their blood pressure, which can be particularly useful for identifying how training intensity and recovery strategies impact cardiovascular health.
The WHOOP MG comes exclusively with the top-tier Life subscription and features a premium SuperKnit Luxe band with titanium components.
Subscription Model and Pricing
WHOOP continues its subscription-based model but has introduced a new tiered structure:

| WHOOP Life | $359 | WHOOP MG | ECG, blood pressure insights, SuperKnit Luxe band | Wireless |
Existing users can upgrade to WHOOP 5.0 for a $49 fee or by extending their membership by 12 months. Monthly payment options are also available, though the annual subscriptions offer better value.
Unlike traditional fitness trackers with one-time purchase costs, WHOOP requires an ongoing subscription to access your data. While some users find this model expensive, others appreciate the continuous hardware upgrades and software improvements included with membership.
For Triathletes: The Ultimate Training Companion
Triathletes face unique challenges in training for three disciplines, and WHOOP 5.0 offers several advantages specifically beneficial to multisport athletes:
Recovery Optimization
The Recovery score provides crucial guidance on when to push hard and when to focus on rest. For triathletes balancing multiple training sessions across disciplines, this insight can help prevent overtraining and optimize performance gains.
A WHOOP-cited 2020 study found that runners who adjusted workout intensity based on their WHOOP recovery score had fewer injuries while achieving the same fitness gains as those who followed a fixed training plan.
Durability and Water Resistance
WHOOP 5.0 maintains the IP68 water resistance rating (swim-safe to 10 meters for up to 2 hours), making it suitable for pool or open-water swimming. The device can be worn during all three triathlon disciplines, though many triathletes prefer to wear it on the upper arm or torso during races to leave room for a GPS watch on the wrist.
Long Battery Life for Race Week
With 14+ days of battery life, WHOOP 5.0 eliminates the stress of charging devices during crucial training blocks or race weekends. The optional wireless PowerPack further extends this, allowing triathletes to focus on performance rather than device management.
Training Load Management
WHOOP’s Strain score quantifies daily cardiovascular and muscular load on a 0-21 scale, helping triathletes balance intensity across multiple disciplines. The system recommends an “optimal strain” based on recovery status, guiding athletes to train appropriately for their current state.
Integration with Triathlon Training Stack
While WHOOP doesn’t have built-in GPS or workout-specific metrics like pace or power, it integrates well with triathlon-specific devices. Many triathletes use WHOOP alongside a GPS watch, with one user noting: “On my runs and races, I sport a Garmin 945 and my WHOOP. Garmin tracks training; WHOOP collects the background stuff for managing recovery.”
WHOOP supports data sharing with Strava and TrainingPeaks, allowing workout details to be imported from your GPS device while WHOOP captures the physiological impact.
