Why You Need To Do Zone 4 Training

[@gcn]

How much zone 4 training do you do? 📊

[@chrisstrider]

80/20 2/4

[@jeffreyscholten.]

More than I plan. I often push myself, I can't help it.

[@brianmurray8943]

I started doing Alp du Zwift pretty regularly. It hurts, but the results are undeniable. I also did the 6 week FTP training on Zwift and that has had some great returns.

[@matthiaswuest7271]

It depends on where I am in my build cycle during the year, but I'd say anywhere up to a total of 2 hours spent at Z4 split over 2-3 sessions in a big training week

[@namedescription320]

[@christoph1]

zone 4 is where i do all my zone 2 training

[@larrylem3582]

I disagree. I think it's fine to go hard for the first 30 sec to get the body up to speed, up to FTP HR more quickly. Like pushing on the pedal on a freeway onramp then backing off once you're up to speed. Else in an hour-long TT, you're wasting time in the first minute.

[@jhoff80]

The other benefit to Zwift for training (for me at least) is that in Zwift I don't have to worry about leaving enough in the tank to get back home.

[@RXP91]

I like my emtb for that! Boost mode home, no assist for higher zones

[@gcn]

Hahahah yes very true! When you bonk you can just raid the kitchen cupboards 👀

[@gerrysecure5874]

I did a lot of zone 4 when I was young. Didn't get me very far. Now I do zone 4 for a few seconds when I go from zone 2 to zone 5. Thats all I need. I'm 60 now and faster than at 35. And feel better between trainings as well. 🙋‍♂️

[@romenorom]

I train in Z2 and Z4 at the same time. 😂 Z2 by power meter and Z4 by heart rate🙈

[@diegoeleazar9154]

Isn't better to do zone 2 with hrm?

[@kurre_kallkvist]

I find I struggle most with zone 2 riding outdoors, it is so easy to go a little bit faster only to realize you've spent half the commute above 90% of max hr... Riding fast is fun 😅 Turbo trainer in ERG mode and a good movie is my recipe for zone 2...

[@twatts4436]

Or REALLY long rides, where getting thr pacing wrong leafs to failure - the 5+ hour marker

[@h20s8804]

I almost can't stay in zone 2 outdoors.... Must be totally flat. Dull as hell.

[@indjke]

@@h20s8804 it’s only when your zone 2 is not developed. The more your train the more speed and ability to cruise over different gradients you unlock. It worth to focus on it. You’ll be rewarded with much more fun later. I know it, I started from just over 2w/kg more than five years ago, now it is close to 3.5. Day and night. You can climb in z2 (if not too steep). You can easily ride over 30 kph staying aerobic. But you need to deserve it.

[@h20s8804]

@@indjke What I mean is, I always want to push harder. It's a personality thing, not ability. I find it easier to do zone 2 workouts on the trainer, ERG mode.

[@walterstevens8676]

I cycled with a HRM for the first time today, just covering a regular route. Obvs my zones aren't perfectly set up, but I was amazed at how difficult it was to stay in Zone 2. Most of my ride was in Zone 3 and 4. Also the delay in getting my HR reading made it a bit difficult to know what my HR actually was at a point in time. My HR seemed to occasionally bump up to well above my thumbsuck max (220-age), and I'm not sure if that was accurate or a result of the wrist-based measure occasionally being out of wack. And if it was accurate, was it me pushing it quite hard or a result of my AFib. I'll keep playing with it because it'll take some work for the HRM to be a useful training tool

[@davidhuffman4768]

Simon, I really love a lot to content you are providing on GCN. The videos on zone 2 and zone 4 training have really been helpful. But all this zone stuff is a bit confusing as Strava, Garmin etc. seem be a bit different in how the designate their zones. It would be great to have a video that discusses all the zones and perhaps the difference across various platforms. My biggest challenge is that while I try to ride in zone 2 based on my Garmin, I end up with the majority of time in zone 3. Based on the question you posed to Dr Inigo San Millan, zone 3 is training no man's land. Love to learn more about all the zones, the benefits of each and advise on how to better managed things if you are struggling to stay in zone 2

[@twatts4436]

Don't know if it's the same on Garmin, but with my wahoo I can tweak the ranges so that platforms match - although I've found that across TrainerRoad, strava, Wahoo, and intervals, they're all within a couple of Watts for each Zone. One piece of advice is to say that for Zone 2 riding don't aim for the very top of it, you'll end up balancing on the edge of Z2 and Z3. So for example, my Zone 2/3 transition happens at arounf 200W, so I aim for 180/190W. It then stay primarily in z2. Another issue is that, any climbs are likely to force you to work harder. Particularly if your threshold is relatively low vs body weight - just consciously try to keep the effort low.

[@lianejackson7170]

You can set you FTP on Garmin, Strava etc and set the zones so they're the same 👌🏻

[@serpadu]

@@lianejackson7170 Sure, but then, which one is the correct one to make it standard?

[@whatwelearned]

@@serpadu Look up Coggan. They're derived from his work

[@oldanslo]

@@serpadu Unfortunately there is no 'correct' zone model that fits everyone, which is why there are so many variations. If you're working with a coach or coaching platform then it makes sense to stick to the zone model that they recommend as they will base your training on it.

[@jimbrittain2617]

These videos from Si are - and have been - absolutely brilliant. They are so thorough and well-described. Hoping this important blend of analysis and execution toward training through focused videos continues. Thank you, thank you, thank you. Si rocks!

[@gcn]

Thanks Jim! Si loves talking zone training 🙌 It's a great way of doing some structured training that you can really see the difference from. Have you found that these videos have helped you improve your riding? 🚴

[@Tuffjobs]

That’s amazing. I go from resting to Max HR immediately!

[@jonmcgoey1772]

I like framing zones in terms of time (Z4 = 1h power, Z3=3h, Z5=5min, etc) because you can check yourself at midway points. As in, "can i sustain this effort for another 45 min... for another 20..." Framing zones that way also gets my mind accustomed to listening to my muscles efforts and my minds ability to mediate and pace. When my legs are yelling out their complaints all I hear is effort. Listening to my heart rate teaches me to pace, but it doesn't teach me how to tell my legs to shut up.

[@fiddleswithbikes]

I like this approach too, however for me my breathing rate is the most immediate feedback I get on level of effort. That said, I don't have any tech yet.

[@lukewalker1051]

I am a long time cyclist and ride most days out of the week. I have mostly latched on to the zone 2 mantra and generally don't participate in fast group rides these days...but like to hammer from time to time if a fast guy comes by...or riding with small group of fast friends. The other day I was trying to hold the wheel of a rider at 22-23mph...I am 69 y.o. and my heart rate kept rising and hit 165 bpm...and stayed there for a mile or two and then I had to fall off because it was a bit too much. A couple of years ago, I could hold this speed or a bit higher. So I have lost fitness by not doing hardly any zone 4. I have a fast heart rate for my age and always have. I guestimate my max heart rate is still about 190bpm or so....nowhere close to 220 - age. My resting heart rate is about 50 or so when I wake up. So zone 2 is great and my overall fitness is good...but...without high intensity training I have lost my power up top. Totally agree with the video. Don't forget zone 4 training if you want to be the best you can be. Thanks Si.

[@CarnivoreDMD]

I’m pushing 60 myself & have become aware of the need to increase protein consumption to avoid sarcopenia that happens with age, also need to lift heavy things. I’m starting to work with KAATSU using Blood flow restriction to help.

[@robdrelich8563]

I’m 62, I only ever max out at 155. Can’t seem to top that. And my HR settles into a high z2 rather easily even on fast group rides. I’m live in a mountainous area, it’s the climbs that get me to a sustained z4/z5 hr But maintaining it, I lack the leg power. Any suggestions?

[@CatManDoSocial]

Well done, Si. XC MTB is a fantastic way to get in Zone 4 training. On my trails, it's difficult to NOT be in Zone 4. I've actually been thinking about this topic for the last several weeks. Anecdotally, I can tell you that I swapped a lot of my Zone 4 training for Zone 2 over the last year, and with all other things being equal, my fitness has noticeably suffered because of it. I am gradually reverting to type.

[@claytonmuller21]

Did you do any structured VO2 training alongside the zone 2? If so, do you keep doing it when doing Zone 4 instead of Zone 2?

[@CatManDoSocial]

@@claytonmuller21 All of my Zone 4 was XC MTB about twice a week but that's as structured as I would get with it. But this last year I pretty much kept my running and indoor rides in Zone 2. I tried to do 80/20. However, I'm in my early 50s now and intensity becomes much more important as you get older. (See Joel Friel's "Fast After 50" book.) I'll be bringing my intensity percentages back to where I've had them for the last 20+ years and hopefully I'll get back to where I was. But this is all very individual. What works for me may not work for anyone else.

[@Azoth5876]

Agreed. I very rarely can stay in z2 when on my mtb trails. Z3 for flats, z4 for singletrack climbing and descending. Means i actually need to be intentional with the z2 workouts as it never happens organically.

[@johnlieto8906]

Great stuff and review as always Si. Finished my end of workout plan Wahoo 4DP test today. So this video is timely :). Balance workouts using a platform like Zwift/Wahoo that gets you in the correct zones is key, but, riding outside and focusing on your ones is really effective as well. Recovery sessions are also key

Yeah thats the brilliant thing: you dont need to do a lot, i do about 4 10min Blocks in z4 per week to Kickstart the metabolism and get the heart ready. For some time a nice base in z2 and z3 and then adding the last bit of intensity. Did it this semesterbreak (6 weeks), the last 2 with intensity and went from 290 to 332 in ftp. Works fantastic to get the System ready for a fitness test

[@gcn]

Wow that is some impressive fitness gain! 🙌 Do you think some sweet spots have been the catalyst for the FTP boost?

[@ChrisGarinet]

@@gcn Definitely. I think just down to the specificity and time spent in zone. Mileage and hours haven’t really changed. I’ll keep using alpe de Zwift for that session and see where it takes me.

Best about Zwift is that you can safely race and go for your limits. FTP tests and vo2max training is good but nothing beats race since then you get your mind into game and you can go faster getting all out of you.

[@andrewdeanenglish901]

I found a simple training plan online years ago which could add in zone 4 training. It consists of one fast ride (I created my own 10 mile tt route for that), one steady ride which was a bit longer distance (zone 2 maybe?), and a longer ride at the weekend, gradually building up the miles for a distance goal over 8 weeks, with the odd workout or shorter rides on rest days, works for me.

[@gcn]

Sounds like a great plan! Are you training for any goals or are you keen to just keep the fitness building and building 🙌

@@gcn I noticed it soon after I started cycling about 9 years ago. It is a 100 mile training plan over 8 weeks, but I reduced it to 25 miles to start with, then 50, then 100. I've went back to it on and off, but it's been over 2 years since I did my last 100. It's certainly kept me motivated 🙂

[@cindymccourt8589]

Huge fan of Zwift. Lots of experience using all its features. I've recently learned several things while training with pro-level coaches, 2 of which seem appropriate to the topic at hand. 1. When using a structured workout, try using incline mode to simulate a freestyle ride. Yes, it levels the resistance but it requires you to focus and feel the resistance, forcing you to generate power on your own. That's good practice. Personally, I toggle between Incline and ERG in a workout depending on the objective workout and how I am feeling. 2. When you use a trainer, you get a different training experience when using your small chainring vs your large chainring. In simple terms, using your large chainring causes a higher flywheel momentum and makes it a bit easier to sustain high power. Conversely, using the small ring requires you to work harder. Conclusion? Better workout on the small ring. Of course, using your small chainring to push higher power is made easier when using a structured workout 🤷‍♀️ Ride on 🚴‍♀️

[@matejstankovic9843]

What everybody fails to mention is how much rest you should be having between intervals. I've figured what works for me through trial and error but that kind of info is pretty important yet never mentioned

Well done, zone Barbra has been favorite training zone since I got serious about training a year and a half ago! Need some time on your hands in an urban setting- working by traveling 100km and 1000m at 30km. It takes some time to build the fitness to but as long as I've followed the rule, every 10km traveled - climb 1000+ meters and I've been in my tempo ride.

[@gcn]

Brab is a favourite for many riders. Nothing better than getting the blood flowing 🙌 Are you enjoying training more seriously?

[@LoganHamilton-z5c]

@gcn I really am. I'm lucky enough to have the Canadian rockies nearby to keep setting harder and bigger goals.

In my experience balance is key. Mon, Wed, Fri, & Sun = Z2 for 1.5 hrs to 2 hrs Tues & Thurs = Z4, Z5, or Z6 for 1 hr to 1.5 hrs Sat = outdoors 100+km / have fun Sometimes Sunday is a recovery ride day.

[@AverageBensCycling]

​@@gcnAlmost entirely on the trainer. It's hard to get a proper workout in around a full time job and with kids. Usually it's a lunch workout and an evening workout after the kid is asleep.

[@BruceDouglass]

I totally have display envy for your Zwift set up. Enjoyed the video too 🙂 I personally do most intervals at 105% FTP for intervals 3-5 minutes in length and 120% of FTP for 60s to 90s intervals. I rarely do intervals longer in length than 5 minutes. I do try to do 2 interval workouts, 1 steady tempo (85-90% of FTP) workout, and several Z2 workouts per week for a total of 12-14 hours/week. Each workout is generally 90 minutes in length except for long ride day. Life is complicated recently by having a cardiac pacemaker installed a few weeks ago that tends to induce heart rate spikes to maximum pacing rate during interval workouts that can last for up to 10 minutes. For context, I'll be 69 next month.

For riding I think that 80% in Zone 2 and 20% in Zone 4 is basically the same pattern so I apply that.

I train one day all out at a rate I can maintain for 10 miles on a certain route that has hills etc and then medium paced 20 miles and then an easy 30+ miles each week....

[@Sutlore007]

What should I do to prepair before training hard? do I need a rest day before hard training session? How much or recommend amount of nutrition to taking in? Or I should go out hard after a cup of black coffee in the warm morning.

In this regard, I'm quite lucky to live where I do. I have vast flat plains immediately to the north and huge mountains immediately to the south. Plains are good for long efforts in zones 2 and 3, as there are plenty of straight, almost empty roads. Some roads are like 60km without turns, which is great for pacing your effort. On the other hand, there are some extremely steep climbs in the mountains, along with some long, not so steep ones and mtb trails. It's just difficult not to be in zone 4 on most of the climbs. Some even require to do a max effort, and some are too steep for me to ride up. There are climbs that are comparable to epic Alps ones. For instance, there is one road that goes from 1000m of elevation to 3200m. And it's not including dirt roads. Some of those go to over 3500 meters.

[@benedictearlson9044]

OK where do you live?! No mountains here in southern England.

[@KL-gl3qs]

Also: dont forget zone 3. very underated overall.

[@paulmorrison30]

Excellent 👌🏾

[@paulcook6297]

I would love to know what proportion to spend on Zone 4 vs Zone 5/6 training? For general cycling fitness.

[@user-bs5yj7zp4r]

no mention of the work to rest ratios

[@Bluleader]

Great vid

[@hojer104]

I feel ridiculous saying this, but with so many variables affecting a ride: sleep, caffeine, food intake, liquid, stress, time of day, weather, sickness, etc., I honestly really struggle to determine whether I'm actually improving.

[@Avianthro]

I recommend more training in Zone 3.639.

[@1barnet1]

If you don’t need sprinting you don’t need any zone 4 block training. You can do zone 3 instead. The problem for me is staying in zone 2 for 80% of the time. Riding in zone 3 is just so much more fun.

[@brianmurray8943]

Was that a #humblebrag showing you doing 347 @ zone 4 on Zwift?

[@9psi]

It also makes for a very fast commute

[@McLovin38FFs]

I’m on heart medication so all my zones from 1 through to Barbera are all the same these days!

[@stoempert]

Really? For me it does put a limiter on the top end heart rate but i can still feel and see the difference between zone 2, 3 and 4.

[@trdi]

I usually warm up for 15 minutes in zone 5 and then do 90-120 minutes of zone 6. Once per week zone 7. My FTP is not definable.

[@Goggles1]

😂

[@ianrbennett]

Please explain how you do Zone 4 interval training with a Robopacer. Not sure how.

[@tubbytoast2]

Robo Si always great

[@suisinghoraceho2403]

How do you incorporate Z4 in a season long narrative? Is it better to focus on Z4 during specific blocks or is it better to spread it out around the season? Given that it is best to not do more than 3 hard sessions a week for recreational cyclists, it is difficult to fit bits of everything in.

[@raymondelliot4605]

I’m 62 years old and any time I go out on my bike or for a run, I’m always up in zone 4 and zone 5. I find it difficult to get down to zone 2 and 3. My recovery heart rate is really good. I never seem to feel tired the next day, but I’m sure it will catch up on me at some point. Am I putting myself at risk?

[@tweeling1977]

I believe you can also training zone 4 to cycling with a backpack with extra weight inside start with 5kg and build it up 😂 the next you feel much lighter and stronger 😂

[@mrnosy1]

I really hope si never leaves GCN. Jeremy Clarkson of the bike world

[@eike345]

zone 4 against the wind and zone 2 with the wind :D

[@RXP91]

The last time I was in zone 4 was when I was doing strength only and had to run for the bus. Am I the only person that doesn’t get zwift? I prefer music for my training. I tried it and I feel like I don’t get it cause everyone seems to love it

[@74_Green]

At least the Barbara zone does not whine like the Karen Zone.

[@phobiamember]

What about VO2max intervals though? 5x4‘ type of work

[@ZhanGeorgiev]

At what heart rate, cadence, and for how long should the rest between intervals be?

[@Solarsystem50]

I love to train in zone 3, just to be a contrarian.

[@RidleyFamily]

You mention two sessions a week at Z4, I thought Dr Inigo said 80/20 unless your ramping up for an event then make it two a week ?

[@seattlegrrlie]

I'm going to do a relaxing evening ride after work... four blocks of zone 4... collapses on the grass afterward...

[@alexarmstrong5611]

I thought the latest school of thought was that you have to include 20% of your training in Zone 5, so Vo2 max to really get the best results? I personally have a bit of an issue we have to be careful with in terms of my HR, so I do what you are suggesting here and my 20% is Zone 4, and 80% zone 2, but that's ultimately limiting my performance without the Zone 5.. ??

[@GuidoPeters]

In general how could one train zone 4 indoor when not having access to a wahoo and zwift. Would a spinning bike do the job as well? Missing out of course on the Strava measurements

[@dylanhunt5368]

I like matching my lactate threshold with as high heartrate as I can reach. When lactate levels get too high, I gear down and pedal faster. And when when lactate levels go down I gear up to push harder. I don't know what this zone is called? Race Zone?

[@antonyadshead965]

I live in Sheffield. Too much bloody zone 4!

[@griffithd05]

Sound editor just went absolutely mad with the effects on this one.
