Whoop Review: Worth It for Tennis Players & Coaches?

I’d been curious about a WHOOP device for a while.

Not because I needed another gadget but because I wanted to understand something simple...

How does a full day of coaching actually affect sleep, recovery, and overall health?

Standing on court for hours, feeding balls, moving constantly, it feels active.

But is it the right kind of load? And how does it show up the next day?

First Impressions

I’d previously used an Apple Watch, lost it (long story), and didn’t really miss it.

So going into this, I wasn’t desperate for a wearable.

I picked up a two-month trial through a friend who wasn’t using theirs. Low risk, good chance to test it properly.

Wearing It (This Part Is Excellent)

I kept things simple and just used the wrist strap.

• Very light

• Comfortable

• Easy to forget you’re wearing it

The “always on” idea is genuinely true.

The charger clips on while you’re still wearing it, which is a small but very smart detail.

I took it off once a week to clean it otherwise, it stayed on.

There are other options (bicep band, clothing integrations), but for coaching, the wrist band worked perfectly.

The App: Simple, but Takes Time

Setup was straightforward.

Every morning you get three core scores:

• Sleep

• Recovery

• Strain

That’s the foundation.

The Journal (Underrated Feature)

Each morning, you log habits from the previous day:

• Alcohol

• Caffeine

• Stretching

• Sauna

• Screen time

You choose what you track.

The key thing:

This isn’t instant feedback. It takes weeks before the app starts linking habits to recovery.

But when it does, it’s interesting.

Tracking Activity (Very Easy)

Starting an activity is simple.

But more importantly:

• You can add sessions after the fact

• Auto-detection works well

• It tracks more than just “exercise”

Coaching, walking, even general daily movement all contribute.

Which is important because coaching is physical, just not in the traditional “workout” sense.

Strain (How Much You Did)

This is basically your daily load. You're given a Score from: 0–21 at the end of your day.

Mine averaged around 16.0 categorised as strenuous.

Which checks out:

Coaching all day is more demanding than most people realise.

Sleep (The Most Useful Metric)

This is where Whoop is strong.

It breaks things down into:

• hours slept vs needed

• consistency (bed/wake time)

• sleep efficiency

• sleep stress

  
  

Plus:

• REM

• Deep sleep (SWS)

• Light sleep

For players and coaches, this is probably the most valuable insight.

Not groundbreaking but seeing trends over time is useful.

Recovery (The One I Questioned)

This is Whoop’s headline metric.

It’s based on:

• HRV

• resting heart rate

• respiratory rate

• sleep

But honestly?

I didn’t fully trust it.

Some days:

• Low score → felt great

• High score → felt tired

So while it’s interesting, I wouldn’t base training decisions purely on it.

Health Tab (Interesting Insight)

This feature takes a few weeks to calibrate.

It gives you:

• A Whoop Age

• Rate of ageing

Mine came out about 6 to 7 years younger than my actual age which I’ll take.

But…

It also suggested I was ageing faster than expected day-to-day.

Why?

Lack of strength training... Fair point.

The Big Question: Is It Worth It?

This is where it gets real.

You don’t buy the device.

You pay for the membership.

• WHOOP One: £169/year

• WHOOP Peak: £229/year

• WHOOP Life: £349/year

No monthly option upfront.

That’s a commitment.

My Decision

After two months, I decided not to continue.

Not because it’s bad — it isn’t.

But because I didn’t think it justified the cost.

Who It Is For

I can see this being useful if you:

• Are chasing specific performance goals

• Want accountability with sleep and habits

• Enjoy data and tracking trends

Why It Wasn’t for Me

I already have a good sense of my routine.

I don’t need an app to tell me:

• Alcohol impacts sleep

• Consistency matters

• Sleep data alone isn’t worth the subscription

What I’ll Take From It

A few things stuck:

1. My lifestyle is generally healthy

2. I should probably lift weights more often

3. HRV is worth understanding better

Final Thought

Whoop gives you data.

But data only matters if it changes what you do.

For me, it confirmed a few things — but didn’t change enough to justify keeping it.

For others, especially players pushing performance, it could be a useful tool.

Just don’t expect it to do the thinking for you.
