Have you ever questioned yourself regarding your energy recovery level? I slept well but I feel kind of tired. Should I train hard today or back off?
Ever wonder if you’re just being a wuss and just need to toughen up? Ever had a day when you felt tired, decided to go on an easy ride, and 30 minutes into the ride you felt awesome and just started hammering?
All of those scenarios have happened to me and I find it to be one of the most frustrating parts of mountain biking. How recovered am I? If you know a little bit about training, you’ll know that riding and working out (strain) wears us down while rest and good nutrition build us back up (recovery).
Too much strain wears us out. Not enough strain and we stay stagnant and don’t improve our fitness. Mental and emotional strain also wears us down and requires recovery just like physical strain does.
I was so excited when two of my students told me about the Whoop strap, it was going to eliminate the guesswork but tracking my strain and recovery! Much more scientific than my training journal (which I stopped using when I stopped competing nearly a decade ago).
I signed up for 18 months at $294.00 plus tax. I’m glad I did it because I have learned a lot.
What I have learned is that Whoop is a good sleep tracker and a decent strain monitor but a terrible recovery tracker (the main feature it advertises). It also has a built-in, digital training diary. Every morning it asks you a bunch of questions: Did you meditate? Did you take a calcium supplement? Did you masturbate? (What, why?) Did you use marijuana? (but no alcohol question, odd) Did you stretch? etc.
WE WILL START WITH THE GOOD: Once you get it adjusted on the correct part of your arm, it does a good job of tracking your sleep (as far as I can tell) and breaking it down to how long you were in bed, how many total hours of sleep you got, how much time was spent in deep sleep, how much time was spent in REM sleep and how much in light sleep.
The sleep tracking works for naps too, which is a nice feature nice because naps are so weird. I often wonder, did I actually fall asleep or did I just lay there. The Whoop Strap tells me I slept and how much time was spent in REM, deep and light sleep.
It does a decent job of tracking strain, but it only uses heartrate data for strain, so a hard weight workout with rest between sets shows nearly no strain (see Dec 16 Screenshot below). As a heart rate monitor, it seems pretty good and it connects to workout tracking apps like Strava which is nice.
WHAT IT STINKS AT: Tracking my recovery! It’s like an opposite tracker. On green days (when I am above 75% recovered), I usually feel tired and need to take a nap. Often, that green day with a nap and very light exercise is followed by a red day (red means I was overreaching). How the heck does that happen? I’m super recovered when I wake up, I take a nap (more recovery) and do little or no exercise (low strain) I sleep well and the next day I have overreached?
My Dec 16 and Dec 17 Whoop Strap screenshots.
This happens pretty consistently. Yesterday I woke up in the green – 91% recovered. That seemed strange since I fully bonked on my ride the day before and had to take a 20-minute break on the side of the trail as I suddenly just ran out of energy. Sure enough, by noon yesterday, I was exhausted and took a 20-minute nap.
After my nap, I did a light Foundation Training workout, went to bed early, and got the best night’s sleep I have had since getting my Whoop strap in October.
Foiled again! After 8 hours and 17 minutes of sleep with 1:42 of REM sleep and 1:15 of deep sleep, I’m only 51% recovered? (My average since getting the whoop strap is around 6.75 hours of sleep a night) How did I lose 40% of my recovery when I took a nap, meditated, went to bed early, and got the best sleep I have had in months?
My Feb 27 and Feb 28 Whoop Strap Screenshots.
Whoop has very attentive, nice customer service, they know me well . I have had numerous email conversations with them and they always say the same thing: the strap isn’t adjusted right. Well, I am skinny, and the strap would definitely read better if I had a little more meat on my bones, but aren’t most endurance athletes relatively thin?
I first tried the strap on my wrist (where Whoop recommends it) and now I wear it on my bicep (where Whoop recommends when it doesn’t work well on your wrist). I have moved it up/down and all around my wrist and bicep and it still either reads poorly or their recovery formula and heartrate variability doesn’t work for me. This is odd as it does seem to track my aerobic exercise and sleep pretty well.
Oh, and they are keeping track of all this data. Remember the marijuana, meditation, and masturbation questions? I’m not worried about privacy issues, but I do think they are going to sell that data to fitness-related companies and I would like to be compensated for participating in their study!
In conclusion, I would not buy this product again and will not renew my subscription when it runs out. It is a decent sleep and aerobic workout monitor, but that is not what I bought it for nor what it is advertised as.
I would LOVE to hear your comments and experience using a Whoop Strap. It seemed to work ok for two of my students so maybe it’s just me?
Please share this article with anyone you think may benefit and feel free to call or e-mail with any questions.
Thanks and create your best ride yet,
Gene
Good review. I have been thinking about a woop for 2 years but my experience with optical HR told me it would be a waste. Thanks for confirming.
I have a suspicion that the very newest Garmin watches might be close but I am unwilling to spend the money to find out. Hopefully you will.
Hi Clift,
Thanks, glad my article saved you the frustration I have felt, and the money! What, now you want me to spend my money to test the Garmin?! Maybe I should do a go fund me to get the money to test it! 😂
Thanks for doing the dirty work for me(puts credit card back in wallet). I had my doubts too.
Hi Chris,
You are welcome!
Cheers,
Gene
Excellent review; very thorough and detailed about what worked well and didn’t work well. Also very timely, since, I am in the market to buy something to help me train in the correct zones, analyze my sleep/recovery, and help me manage my riding performance. I won’t be wasting my money on the Whoop strap.
Thanks Christopher, sounds like Garmin has a device that may be better.
Cheers,
Gene
My big takeaway was when Gene said he rested 20 min trail side. I thought it was only me who did that 🙂 seriously! I have t seen a rider resting on the Gateway loop or Lost Dog Wash (Scottsdale) since moving here 5 months ago. Thanks for the timely article as I was wondering how many days I should give it between what I would consider a big ride when you find yourself resting from a bonk
Hi Lee,
Trail side naps are the best! Seriously, if you totally bonk you need to listen to your body and return slowly or you can really dig yourself a hole. Ironically, that’s one reason I purchased the Whoop Strap, to take the guess work out of situations like that!
Cheers,
Gene
Interesting. I have A Garmin Forerunner 245 watch with wrist HR monitor and O2 saturation sensor. I bought it to track hikes and lunch walks and to occasionally back up my bike computer. The HR monitor seems to read low compared to my chest strap HR monitor during activities, but HR at rest seems accurate. I thought the wrist HR and O2 sensor was kind of a gimmick, but it’s a pretty damned good sleep monitor and I’ve found that it’s a great recovery monitor. It works off of heart rate variability to give you what Garmin terms your Body Battery (Basically your % recovered). It’s pretty much spot on for me. I got my first Covid vaccination last week and it really affected me with elevated heart rate, sleeplessness, fatigue which all showed up as poor recovery (low Body Battery) as low as 5% for two days straight. I’ve never seen it below 25% say after an overreaching type effort. Basically, I would recommend it because it seems to do what the Whoop Strap failed at. I would assume the pricier Garmin watches would do as well as better.
Thanks Mark! I think I will give the Garmin a try. Blanton who replied earlier to my review wants me to test it! Hopefully he reads your review!
I hope your battery is back over 50%! Cheers, Gene
Mark Bates, you are everywhere!. Great comments on the Garmin. I have the Vivoactive 3 and find it does a great job at sleep tracking but its recovery suggestions are out of wack. I do an average workout and it wants me to recover for 3 days. Gene thanks for the review on the Whoop, i was curious about it as well.
Hi Jim,
You are welcome. I definitely have a few students who love their whoop. I think it may just be how tight you wear it. I had a student this weekend show the imprint it leaves on his arm. I’m testing mine that tight, don’t love the way it feels so far! Will give it a few more days.
Cheers,
Gene
Finally an honest review. I feel like all I see are sponsored reviews singing the praises of the product, and I don’t believe most of them.
Hi Julie,
Yeah, sometimes it nice to not have to please sponsors!
My body battery was 5% for two days after the vaccination. It was 82% this morning, so it seems I’ll survive.
Excellent! A little nervous about the vaccine but I plan on getting as soon as it is available!
Gene, your experiences with Whoop seem very similar to my own. I love how much insight it has given me into my sleep. I am too exhausted (too exhausted for much of anything) on green days to complete any real workout, but I get my best workouts on yellow and red recovery days. It just does not add up with Whoops articles and feedback from their staff.
My best workout days are days where my sleep was short, but my body optimized deep sleep. Those show as yellow or red.
Another issue I have is with strain. I think the strain formula is geared towards those who are already athletes. I am a formerly fit person (read now moderately obese and not conditioned for heavy strain) who wants to return to that status in my middle age.
Even after months of almost daily use, reaching optimal strain will make me unable to exercise for two to three days after. It also takes three plus hours a day as I can easily overtax my cardiovascular system. I think a heart attack might put a crimp in my fitness plans… Whoop does not take into account fitness conditioning levels and bodyfat levels. I too plan to discontinued my subscription.
