Whoop 4.0 Overview: Improved Accuracy Makes The Whoop Band A Helpful Sports activities Monitoring Instrument

The Whoop 4.0 is a substantial enchancment on the three.0. The guts charge monitoring, throughout each exercises and when at relaxation, has develop into extra correct. Coupled with this, its pressure monitoring generally is a helpful method to make sure you’re coaching on the proper stage to enhance, no matter your chosen sport is. The sleep monitoring can be good, though the general restoration monitoring falls quick in contrast with different gadgets just like the Oura ring.

Score ⭐⭐⭐ (3.5/5)


  • Improved coronary heart charge monitoring accuracy
  • Good sleep monitoring
  • Comfy band
  • Detailed insights into a variety of stats
  • Smaller than Whoop 3.0


  • Questionable restoration scores
  • No display screen or GPS
  • Month-to-month subscription

The Whoop band shouldn’t be your typical health tracker. It doesn’t have a display screen and it focuses on two foremost measurements: pressure and restoration. Every night time the band tracks your sleep to present you a restoration rating the next morning, after which every day you get a pressure rating primarily based on how a lot exercise you’ve carried out. The purpose is to make sure your pressure rating is according to how effectively recovered you might be, and the Whoop will coach you to realize that.

Once I examined the Whoop 3.0 all of the insights it provided have been undermined by the inaccuracy of its coronary heart charge monitoring, which meant my pressure scores have been flawed a lot of the time. The brand new Whoop 4.0 improves the sensors within the band, turning into a much more helpful product within the course of, although the restoration facet of its monitoring continues to be not totally dependable.

The band additionally stays a reasonably area of interest product because it doesn’t have a display screen or GPS so it can not exchange a sports activities watch. Relatively it’s finest used alongside one other system, which may really feel like overkill, particularly given the Whoop prices £30 a month (although this worth drops whenever you decide to a subscription for an extended interval).

What’s New?

A very powerful change on the Whoop 4.0 is the brand new coronary heart charge sensor, which has 5 LEDs – three inexperienced, one pink, one infrared – in contrast with the 2 inexperienced sensors on the Whoop 3.0. In addition to rising the accuracy of the center charge monitoring, the system can take measurements of pores and skin temperature and blood oxygen saturation.

One other massive change is that the brand new band is 33% smaller than the earlier model, however the battery life stays the identical at 5 days. You too can now put on the sensor in additional methods: the Whoop Physique line of garments has pockets for the sensor so you may put on it within the waistband of your leggings or underwear, or in a bra. I wasn’t capable of attempt the Whoop Physique gear, so wore my Whoop round my wrist, forearm and biceps when testing it out.


The Whoop 4.0 is a light-weight, waterproof band that’s snug to put on 24/7. Even when moist after a bathe I discovered the band didn’t develop into unpleasantly clammy on my wrist or arm, and it dries rapidly. You possibly can put on it 24/7 due to the intelligent design of the charger; you cost a mini battery pack that then slides on to the band to cost when you put on it. The brand new Whoop’s battery pack can be waterproof, so that you want by no means take it off – you may even bathe whereas it prices.

I discovered the Whoop 4.0 with its new, smaller band snug to put on. A sleeker design is all the time welcome if it doesn’t come at the price of battery life and the 4.0 lasts the identical 4 to 5 days that the three.0 does on a cost. At occasions finding the battery pack charger after that interval was a little bit of a faff in contrast with simply plugging the band itself in, however there have been a number of events when with the ability to cost the band with out eradicating it meant I might head straight for a run or different exercise whereas carrying it as an alternative of ready for it to cost.

Pressure And Restoration Monitoring

On the face of it, life is easy in Whoop world. You place your physique below pressure every day (scored as much as a restrict of 21), and every night time you recuperate, with that restoration rated out of 100% within the morning. You possibly can then use these two scores to evaluate your coaching: pushing your pressure past your restoration ranges within the quick time period will see enhancements to your health, however you must make sure you get sufficient relaxation and don’t overdo it for too lengthy.

That is all that Whoop does. It received’t log your step rely or observe how far you went in your run or cycle. It retains issues comparatively easy with these two scores, though there’s numerous information underpinning them.

Your pressure rating is decided by coronary heart charge – the upper it’s the extra pressure you’re placing in your physique. Pressure largely accumulates whenever you train, however also can come up from every day exercise. The inaccuracy of the center charge monitor on the Whoop 3.0 steadily led to my pressure being overestimated as a result of the readings have been far too excessive after I wasn’t exercising.

This downside happens much less typically on the Whoop 4.0. Once I wore the band on my wrist it will generally learn a bit of increased than my precise coronary heart charge and log some “pretend pressure” within the day, however by no means a lot that my pressure scores have been considerably affected. It additionally didn’t log phantom exercises, one thing the three.0 did commonly.

Nonetheless, throughout exercises I did discover that I needed to put on the band on my biceps to get dependable readings, and after one notably dangerous run the place the center charge studying from the wrist was miles too excessive the entire time, I moved the Whoop to my biceps completely.

When in place there, I’ve discovered the pressure recordings correct over an extended interval, and you’ll even use the Whoop as an exterior coronary heart charge monitor to hook up with your watch by setting it to broadcast coronary heart charge within the companion Whoop app.

Exercises are tracked routinely by the Whoop band and when one is detected you’ll get an alert to take a look at it within the app, prompting you to offer extra data corresponding to what sport it was and the way laborious you discovered it. You too can observe exercises manually by beginning them within the app, however the automated system works effectively and there’s little to be gained by manually beginning a session for the reason that Whoop band reveals no stats to take a look at mid-workout.

Every day you might be additionally given a advised pressure score within the app to purpose for, which is difficult to do provided that the Whoop lacks a no display screen and gives no steering throughout a exercise. Nonetheless, when you begin a exercise within the app you may set the pressure coach advice as a goal and work in the direction of it when you all the time have sight of your telephone. I discovered that after you get a really feel for the way the pressure rating tallies as much as your exercises you’ve a tough thought of what to purpose for in your foremost sport. For instance, as a daily runner I developed a way of what Whoop pressure rating a 60-minute simple run would give me.

The restoration score is extra sophisticated, and I discovered this half of the Whoop service much less spectacular. The rating is predicated on how lengthy you slept, your coronary heart charge variability (HRV), your resting coronary heart charge and your respiratory charge in a single day, with HRV a very powerful issue.

To confuse issues a bit of there’s additionally a sleep efficiency rating within the app, which simply covers whether or not you hit Whoop’s really helpful hours of sleep that night time. This has three settings: the quantity it is advisable to be at your peak, the quantity wanted to carry out, and the quantity wanted to get by.

Usually I ignored this somewhat simplistic rating, together with Whoop’s suggestions for sleep period. Typically it advised me to sleep longer within the morning to extend sleep time with a advised bedtime of after 11pm, when to my data it’s way more useful – and extra sensible – to get to mattress early when you’re seeking to enhance sleep time somewhat than mendacity in.

The restoration rating is extra helpful, however I had many days the place I didn’t really feel in tune with the rating it was supplying. This contrasts with the monitoring from the Oura ring and its readiness rating, which is mostly on level. Whereas the Whoop 4.0 all the time appeared to nail the occasions I fell asleep and awakened, I quickly discovered I couldn’t depend on the restoration rating as an correct indicator of the state of my physique every day.

There have been occasions when it was clearly out of whack too, corresponding to the times after my COVID booster jab after I had negative effects like muscle aches, chilly signs and night time sweats. Although the band measured that my pores and skin temperature was as a lot as 2°C above common, this was nonetheless rated as inside my regular vary on the well being monitor dashboard, which additionally reveals stats like HRV and resting coronary heart charge.

On the primary and second day after the jab the Whoop did give me a low restoration rating, however that was it, and within the days following I used to be again to excessive restoration scores way more rapidly than I felt it really took for me to recuperate. As compared, the Oura ring demanded I enter “relaxation mode” for a couple of days following the jab and clearly marked out my excessive pores and skin temperature as trigger for concern, with easy recommendation to relaxation.

All the data logged by the Whoop is no less than introduced in participating trend inside the companion app. This does a very good job of offering top-line data like your foremost pressure and restoration scores on the homepage, so these seeking to get out and in of the app rapidly can get what they want. Then there’s way more element deeper within the app for many who need to pore over their stats. You additionally get weekly and month-to-month assessments with graphs that present how effectively you’re managing your pressure and restoration over time.

Ought to You Purchase It?

As soon as I moved it to my higher arm, the Whoop 4.0 logged dependable sufficient information on the pressure entrance, and as a eager runner I discovered the knowledge helpful and it helped me create a balanced coaching plan. And regardless that the restoration monitoring isn’t fairly as correct in my expertise, it does nonetheless present a very good guideline rating you should utilize every day to charge your sleep.

Total, the Whoop 4.0 is an attention-grabbing product that may assist very eager sportspeople handle their coaching, however it’s not excellent, and that’s an issue given its worth and the competitors it faces. Whereas the band is free with a subscription, you pay £30 a month for the Whoop app on a six-month contract, and although that worth does drop to £288 general for a 12-month membership (£24 a month), or £324 for 18 months (£18 a month), it’s some huge cash to spend on a tool you’ll in all probability be utilizing in tandem with a sports activities watch that gives comparable information. Garmin has its Physique Battery measurement plus coaching load and restoration recommendation, though its sleep monitoring is usually inaccurate, whereas Polar has sleep monitoring on a par with the Whoop and wonderful coaching load evaluation.

To make a extra area of interest product like Whoop worthwhile it must be nearly infallible within the areas it does cowl, and in my expertise that isn’t the case with its restoration monitoring. As well as, inside this area of interest there’s the Oura ring, which is a extra correct sleep tracker that gives readiness scores for judging your coaching, in an app that does a greater job of offering easy, actionable recommendation somewhat than the wealth of knowledge Whoop simply throws at you.

Whereas I just like the design of the Whoop 4.0 band and app, and it does roughly ship what it units out to, it isn’t spectacular sufficient that I’d use it over and even alongside a sports activities watch.
