So no matter your sport of selection, be that bouldering or wild swimming, the Whoop 4.0 by no means wants to go away your wrist.

Nevertheless, throughout endurance actions the place you might need to examine your coronary heart price, significantly if you’re trying to make use of completely different cardio coronary heart price zones in your coaching, not having a wrist-worn show was a giant miss.

Once more breaking conference, the Whoop 4.0 has an elasticated “SuperKnit” band which you’ll be able to tighten or loosen like a rucksack strap earlier than slipping into place over your wrist, moderately than the buckled silicone straps seen on most health trackers.
This by no means felt uncomfortable or prompted irritation to our pores and skin throughout the testing interval, although the color turned barely dirtied over time as you may’t wipe it clear like a silicone strap. However, you should purchase interchangeable straps with different colors if you need a contemporary look.
Our favorite design function of the Whoop 4.0 is the charger.

This implies, in contrast to most of its rivals, you don’t must take away the band to cost it up. As an alternative, you may replenish its battery on the go and proceed monitoring 24/7.

- Actionable recommendation for improved efficiency
- No GPS
If that is the place you anticipated the Whoop 4.0 to adapt to health tracker norms, assume once more. It omits the same old transfer objectives and step counts fully in favour of pressure and restoration scores.
Pressure is a measure of your day by day cardiovascular load primarily based on The Borg Ranking of Perceived Exertion (RPE) Scale. The longer your coronary heart price stays at an elevated stage (reflecting how exhausting your circulatory system has been made to work) the upper your pressure might be, with a remaining rating for the day delivered out of 21.
The band tracks this utilizing a know-how known as photoplethysmography, with LEDs on the underside of the sensor suite shining mild into your pores and skin and the capillaries beneath the floor. Blood absorbs extra mild than the encircling tissue, with any unabsorbed mild mirrored again and acquired by a sensor known as a photodiode, displaying the wearer’s blood stream and coronary heart price.
Restoration is given as a proportion and signifies how prepared your physique is to tackle pressure. The rating is calculated utilizing your complete quantity of sleep, respiratory price, resting coronary heart price and coronary heart price variability (the variance within the time between your particular person coronary heart beats, with larger variance related to a better stage of preparedness for strenuous bodily exercise).
You may view these individually, in addition to a breakdown of your levels of sleep (awake, mild, deep and REM or speedy eye motion) from the night time earlier than.
Whereas the person metrics will enchantment to hardcore health followers, we discovered the pressure and restoration scores are a great instrument for gauging your bodily preparedness at a look and adjusting your coaching accordingly.
Efficiency
- Considers extra than simply sleep to calculate restoration

- Helps athletes stability coaching and relaxation
The compact Whoop 4.0 is snug and discreet. Placing it on could possibly be a bit awkward as it’s a must to take it off to tighten the strap earlier than sliding it again over your hand. Nevertheless, when in place, it stayed put all through excessive impression exercises.
The sensor suite (33% smaller than its predecessor, the three.0) feels hard-wearing, displaying no indicators of injury when clattered with kettlebells or worn whereas wild swimming. It provided steady monitoring of a variety of well being knowledge too, together with coronary heart price and estimated calorie burn, displaying which actions positioned essentially the most pressure on our cardiovascular system.
However it’s the multi-dimensional method to calculating restoration that’s the jewel within the Whoop 4.0’s crown. By contemplating coronary heart price and coronary heart price variability, in addition to sleep amount and high quality, it offers a extra rounded view of your readiness for train.
Days the place we acquired low restoration scores correlated with days we felt sluggish. To counter this, the app affords ideas to enhance your scores as nicely offering a day by day optimum pressure stage to hit (if you wish to get well for a race or session later within the week) or exceed (if you wish to enhance your cardiovascular health ranges).
This actionable recommendation – alongside steerage on when to go to mattress – is simple to implement and helped us really feel more energizing the next day. We additionally appreciated the inclusion of a day by day journal on the app, the place we may document our behaviours and see which elements (reminiscent of creatine or alcohol consumption) might have impacted our readiness for train. By recognizing hyperlinks between sure behaviours and a plummeting restoration rating, it helped us develop habits that made us really feel replenished the subsequent day.
Verdict
The Whoop 4.0 isn’t for these looking for their first health tracker, neither is it for runners seeking to hold monitor of their tempo, route and coronary heart price – courtesy of its lack of display screen, step counter and GPS.
As an alternative, we discovered it’s higher suited to intense actions like HIIT, CrossFit and crew sports activities, the place you could possibly sit down after a recreation, match or exercise to take a deep-dive into the info.
The place it actually comes into its personal, nonetheless, is as a 24/7 health tracker, sending a wealth of data out of your wrist to your cellphone (so long as the 2 are linked through Bluetooth). By constantly monitoring your coronary heart price, sleep and extra, it gives pressure and restoration scores which, when used to information your coaching depth, can assist you are feeling replenished and able to carry out at your peak.
At £30 / $30 / $44AUD monthly, the fee can shortly add up. However, if you wish to put money into all aspects of your well being and discover out extra about your physique, we predict it deserves this value.
