> [@kurt.braeckel](#): > > I don’t think any of them have _really_ trained VO2max before. Quoting myself here… I remember the first time I did VO2max workouts in TrainerRoad back in I want to say 2017. I had gone to bed ready for the worst the night before… as a former track runner, I was used to sets of 800s and 400s and 200s till I wanted to puke to work VO2max, never breathing that hard before in my life. I did the old TR MV plan workouts with VO2max and was like “that’s it?” Spencer +2 was the first one that got me even a little bit. And then I did a short power build and those were _pretty_ good… but I think the biggest thing TR lacks (and it would be nearly impossible to write this as a TR-style workout where you do structure at XXX% of FTP for everyone) is proper VO2max training. And I think that explains why a lot of athletes that come to some of us as coaches after doing %FTP based plans see some immediate gains from blocks of proper VO2max training. Everything is primed, but you’re kinda at your current ceiling and haven’t done the right stuff to raise it just yet. That to say, if you’ve stagnated on TR FTP/SST plans, maybe try their short power stuff. I’m not stumping for all of you to hire coaches… just to do things that are going to challenge/stimulate MAP (VO2max??) a bit more when the time is right. … or hire me, that works too. 😆 😅 🍻 ---

Has anyone considered VO2max intervals on an assault bike or airdyne? With the arms moving you should be able to put in more time at VO2max overall while needing to push less watts through the pedals. ---

I can definitely feel how powerfully my heart is beating, sometimes. I would think this correlates with relative stroke volume (as a percentage of maximal stroke volume). The sensation of a heart beating rapidly but not very powerfully is quite different from that if it beating powerfully but not very rapidly. ---

The thing is, I swear it used to be harder. Back in the day, low volume plans had me doing a lot of three and four minute intervals that were properly intense. Since levels came out, things changed. Real VO2max training doesn’t start until about level five or six. Traditional 5x5s are nowhere to be found below somewhere around level seven. The only hard Vo2 workout I have been made to do was only hard because I did it outside (so no ERG, and it was at higher and higher altitudes) and because it the sheer number of intervals. ---

Back when I did TR plans I junked the stuff that was in their plans and did my own custom VO2max blocks based on their workouts. I think I started with 5x3 and progressed that to 7x3 then some longer stuff. I’d do it differently now… but to me coming in with some fitness and familiarity with VO2max training prior, doing Taylor -2 and the like was a waste of time. I stopped using TR before adaptive training when I had time to start programming for myself, so I can’t speak to any of that. ---

As someone relatively new to VO2 max workouts (and structured training in general), I’ve been reading this and wondering how this applies to me. As I’ve thought about it, it seems like the consensus is that VO2 max is not about a percentage of FTP and that we need to target the maximum repeatable power (just to regurgitate wording a number of people have used). That’s all well and good, but how do we get there? As someone new to training in this zone, it seems like it would be really easy to pick wrong and blow up. I can absolutely imagine some future point where I’m experienced where I can tell by RPE what’s sustainable. But I find this especially hard to do because my max sustainable power is different on 30/30s from 50/50s (todays workout) or 40/20s, and also potentially from multi-minute efforts (I’ve only ever once done those before deciding to try out TR). That power will vary by the number of intervals within a set, and how long the rests are between sets. Or so I would guess at least. And that’s where adaptive training should come in (I say ‘should’ because I haven’t been using it long enough to know for certain). Both preparing us for true VO2 max efforts, but also helping us find it without going to far and blowing up. For those who are critical of TR, let us know if there’s another way to get there without something like adaptive training (or if you find it doesn’t actually work like I’m hoping). ---

> [@kurt.braeckel](#): > > That’s generally done by achieving the hardest breathing you’ve ever done in your life and sustaining that for as much time as you reasonably can. What is a typical range of duration for this experience (per interval)?. My most recent session, it was the last 45secs of a 5min interval. Outside, I’ve done extended bouts of “fish out water” at the end of races or going for KOM’s. I reckon that accumulating even 10min of this experience in a session is very challenging. ---

Tr has a good library without needing to create a workout that is probably already there. I’ve starred my favorites so they now come up easily in the search. For progression of 3 minute intervals this was the final 3 weeks of ssb2, ending with a pl of 8. AT will get confused though if you aren’t close enough to target and probably consider these as high failure rates, but imo dropping power a bit the last rep or two doesnt diminish the goal of a 6x3 minute workout. ![Screenshot_20230303_090832_TrainerRoad](https://global.discourse-cdn.com/trainerroad/original/3X/1/8/188b0d95e5fbfde969a4167a9ba47b6fd558542c.jpeg) ---

Don’t over think it just push as hard as you can if you blow up so be it you’ll have started to get an idea of your capabilities and you will be less likely to blow up in the future. I’d recommend not doing them in ERG but resistance mode then you’ve got more freedom to push a little harder and, if it happens, blow up without worrying about it. ---

> [@buirechain](#): > > That’s all well and good, but how do we get there? As someone new to training in this zone, it seems like it would be really easy to pick wrong and blow up. I’ve just gone through this myself, and honest answer is that’s where turning off erg mode comes in and just giving it a try. Looking at my 5x4min workouts my AVERAGE power was about 115%. But what I’d do is start with a hard start where I spin up over 130 rpm for 10-15 seconds, drop to 115-120 rpm after that, and try and hold it 115 for the remainder of the interval with the goal of getting ready to crack and start losing power right at the end of the last interval, but if I start dropping much below 115 and can’t hold it, downshift again and try and bump the cadence up. For reference, I had my trainer set where 115 rpm would put me right at that 115% FTP area but that could be different based on what I can handle vs. someone else. Feeling strong, spin faster, cracking - cadence drops or drop power/downshift. There’s some feel to it that you don’t develop when you only ride in erg mode. Blowing yourself up or coming out too hard can teach you what you’re really capable of that you don’t really develop just riding TR workouts in erg all the time. ---

> [@buirechain](#): > > That’s all well and good, but how do we get there? You just go max. But if I were you, I’d just follow the TR plan. Just because TR puts a VO2max label on the power target doesn’t mean you should be going max every time you see that label. ---

Thank you for pointing this out. The idea of being able to tell if you are having changes in stroke volume at a moment in time would come down to a feeling of changes in milliliters. ---

Yeah, it can be hard to get that sensation for much more than 10 minutes. Done right - the way I’ve done them the last four years or so and the way I prescribe them (IMO) - I start breathing fire about 2 min in, +/-. So on longer sets I can get up to 12 or so minutes breathing like that, and then on shorter sets like 7x3 it might only be 6-7 minutes, but it’s still a stimulus. > [@redlude97](#): > > like kurt suggests of 7x3 are proven 7x3 is usually the last round or two I prescribe when people are really tired. Conversely, it’s also one that I’ll use as the second set of a two-a-day or back-to-back days for people who’ve never really done it before. In general, I’d prefer most sets to be 4 minutes or more because it does take some time to “breathe fire” and you want that going for as long as possible. That said, it’s probably not possible for most people to do 6 or 9 sets of 4x5 or 5x5 minutes like that over the course of 2-3 weeks without wanting to throw their bikes in a river. ---

> [@buirechain](#): > > That’s all well and good, but how do we get there? As someone new to training in this zone, it seems like it would be really easy to pick wrong and blow up. Absolutely something that happens to just about everyone. But you don’t get your first 20 min test right the first time… you probably don’t nail your first 40K TT. As with all things, there’s learning involved. I coach VO2 sets with some flexibility. I always program them via trainingpeaks so that people that use TR/Zwift have something to follow. I use a 1:1 work:rest interval, but I tell my athletes that the rest is flexible, and to take more if they need it to get quality reps in, up to 2x interval length. When I do these, I usually am taking 1:1 at the start and then by the end of a day I might be taking 1.5:1. It’s OK. Dialing in things like the hard start and what works for you can be tricky. If you’re anaerobically inclined, you want a shorter hard start and to make sure you’re not blowing yourself out. If you’re less anaerobically inclined, a longer hard start will help get your HR and breathing ramped up. Then you make sure you’re focused on the right thing: cadence. Too often people get wrapped around the axle about power, when cadence and going as hard as you think you can is more important. Once you get that fire breathing sensation, you know it… and you know if you successfully replicated it or not. After a few sets, most people get it dialed and can make adjustments on the fly, just like most other workouts. Feel free to DM me if you want more info. No reason you can’t use a TR workout to do these, but you’ll just want to turn off erg mode and manage the effort yourself. ---

> [@buirechain](#): > > That’s all well and good, but how do we get there? As someone new to training in this zone, it seems like it would be really easy to pick wrong and blow up. The issue is that there is a longer discussion required. The term “VO2max” refers to several things, and it’s easy to get lost in the weeds if you are new to structured training. Since you are new to structured training I’d say it’s better to follow the plan, focus on consistently riding your bike/trainer, and don’t use the word failure when looking at completed workouts. The biggest “mistakes” you can make is to a) not consistently ride your bike/trainer, and b) not slowly increase the amount of time you ride from year to year. The details and forum debates are far less important. ---

I sometimes will give stuff like 30/15s or even 30/30s just to get used to intensity first, but it’s like one or two sets and usually for people I’m worried may not handle big intensity well right off the bat. Otherwise, rip the damn band-aid off and here’s your 3x6 or 4x5. 😈 ---

@kurt.braeckel what do you think about billat style vs sustained VO2? Do you have a preference for different athletes? My favorite vo2 workout is megantic because of the hard start, and I’ve gotten up to Megantic+3 (5x5 of hard start followed by 125/88% 15-15s) in the past which is a bitch but held my HR very high for much longer duration. ---

I strongly prefer sustained VO2max intervals for training VO2max. If I want people to operate at higher power (e.g. MAP training), I’ll do more 30/15, 40/20 stuff. If someone just can’t/won’t do the sustained VO2 stuff, then I’ll prescribe some billat-style intervals for them but it’s a compromise IMO. I give my true masters (60+) athletes more on/off stuff than anyone else. I did like the billats when I did them with TR, and I found them more effective than 30/30s for sustaining high efforts, but they’re crit training more than training VO2max in particular. But again, I don’t worry about holding HR high. I want breathing as high as possible, LOTS of muscle contractions in the legs (high cadence) to force higher venous return. HR is essentially tertiary. It’s high by necessity, but I’m not looking for particular numbers or time spent above XX% of HR, personally. ---

I thought the purpose of 30/30s (and its variations) are just very different from VO2max workouts with long, sustained intervals (7 x 3 minutes, 5 x 4 minutes, etc.): the former aims to increase your anaerobic capacity. As far as I understand, neither is a substitute for the other, they just complement each other.
