Im so hyped every time I see a Lionel video popping up on my main page!

Might want to have a look at that leg kick 😉

Hi Lionel, thank you for this excellent video. I believe there is a lot of very useful data to be gleaned from this session. 1. Your pace at lactate threshold (LT2) is 1:14-1:15, which is about 10 seconds per 100 slower than the fastest triathlon swimmers. I am guessing that you can bring this down to 1:10/1:11 within about 3 to 6 months once you get back to heavy swim training with Gerry. 2. Your maximum lactate production is quite low. Most fast swimmers would probably produce 6 to 12 mmol/l during an all out 400 swim. 4.5 mmol suggests that your anaerobic system is very underdeveloped and/or your current technique does not allow you to swim at speeds necessary to produce those numbers. High end swim speed is of course very important given how pro triathlon swims are often all out for the first 200 yards or so. I am sure Gerry has a plan for this as well. Good luck!

This is intersting AF. You're now a pro KZfaqr my friend. Keep this up and your going to get every age grouper nerding out on your channel.

Point the foot, lock the knees, hold legs closer together 😊

I'm just starting out and swimming is by far my worst discipline. I have minimal experience running and no biking and swimming experience outside of my last two months of training. Watching these videos has definitely increased my drive to want to train harder and learn more about everything to improve my overall ability. Love these educational videos!

Great video! You got me hyped for seeing the progress over your lactate in the next few months. That's kind of crazy, I never thought I would be so invested on someone else's training. It's very helpful to see the science behind this study. Keep up the good work ❤

Keep up the good work mate! Stoked to see the analytical approach towards fitness gains! Side note, I signed up for my first ever 70.3 ironman thanks to you. Would be awesome, if you could do a competition in South Africa one day.

This was absolutely fascinating and as someone who appreciates data and analysis of data sets, I was geeking out. But also incredibly interesting how much your Lactate jumped with a huge increase in effort without a lot of gain of speed. I love this because it only confirms how much swimming is so technical and important to create GOOD and STRONG Form from the very beginning before you can even talk about getting faster. Thanks for doing this!

I feel like the high elbow catch of Lionel is looking better !

Thanks for still putting out content! Makes the off season a little more bearable as a fan of the sport not to mention these geeky insights are very interesting!

The data looks great, very well-defined, very useful. The conclusion is spot-on, too. Practice technique, test every so often, get those curves moving to the right. I'm not sure why he talked so much about gathering data and not needing it since it is obviously needed.

Thanks Lionel. Besides being one of the most inspirational athletes, you are also producing the most interesting videos in the field. I am so eager to see you succeed.

Wow, Lionel seems a lot more grounded than he has in other recent videos. Refreshing.

Really loving this content. Seeing this is not only motivating but extremely educational. Thank you!!!

Well done Lionel for finally putting some real science behind your training and racing. This will pay huge dividends to you in 2024.

Great video. I'm starting to now believe that you'll make an excellent coach one day. Keep surrounding yourself with the best, and please keep listening.

Great Video :) thank you Lionel. Lots of love from Germany

Dedicated triathlon coach. Been guessing for years. Guidance from one great coach is probably a good idea. Don’t reinvent the wheel, just improve the wheel. Time is ticking. I’m a big fan and wish the best for next year.

1:22 per hundreads yards with 104 hr 😂 mines higher than that going for a walk Lionel’s a beast 🦁

Thanks for sharing. You got this Lionel

I'm really enjoying these testing videos and am excited to see how things progress over the next 8 weeks. Will these results be used to dictate training or just to have a benchmark for comparisons?

in my opinion that is not Lt2, but closer to LT1. LT2 usually is around 3,5-3,8

Great video and explanation of what you are doing on this set and future sets. You are more than welcome to come and swim with our Masters group if you are ever in the Charlotte, NC area.

More data if needed smart. Looking forward to next test

Love this stuff!

Great video ! Thx for sharing. Would love a link to the d max formula

Physique looks incredible!

Thanks Lionel for sharing

Awesome video!

Great video!

Really interesting video ! Thanks

You are an inspiration, Lionel. Are you and your swim coach looking at your underwater catch and pull? Improving this component of you stroke will improve speed and efficiency, allowing you to swim faster with less effort.

Work on technique is much better than treating swimming as a fitness focus sports

More great content, really interesting and what you’re saying in the pool at the end makes total sense- this data is interesting but not crucial for developing swimmers.

Gainzzzzz to be had! Go get ‘‘em Sir!

Gerry’s key principles are prioritised as tautness, alignment then propulsion. It appears to me that as you work on your tautness, which will include ankle flexibility work, your tautness will naturally improve and then you will naturally move through the water at a greater velocity using the same energy. As you state, knowing such data will if nothing else increase your belief in the process. Thanks for sharing. It would be great to also get Gerry’s input on camera [I did watch you on his Tower 26 podcast]

Fascinating! Should you reverse the order of the test? To rule out the possibility of cumulative lactate and stress.

M. SANDERS, Thanks for your video. Data are very important but efficiency comes with a properly technique. Because swimming is a technique activity. Yours is not good enough, you can do much better!!! I wish you the best, god bless you! Jeoffrey NIERDING triathlon coach since 1999.

Vlacmax y good test for Glucolitic power vs Aerobic power. Book Jan Olbrectch is good for this concepts, Nice Job LS, good luck in seasion 2024

How do you use this in your training, are you going to apply the know 80/20 Aerobe/Anaerobe training. So improve your slow muscle fiber and build a bigger aerobe zone, moving LT1 towards LT2?

Nerdy question alert ! :-) Since Swiming is such a technique heavy sport, do the same principals apply like run/bik with regards to these Lt1/2 zones when we are targeting development of different energy systems. Put differently the long easy rund rides are done to develop mitochondrial efficiency and capilary density. Do we also target this in the swim ?? Or are you, in the swim just looking at the Lactate as a measurable metric to test the efficiency of your technique.

First few seconds I thought Lionel went fishing

Just wondering what his next epiphany will be. Might be time to move to Andorra like a lot of young pros.

I noticed when you're breathing, your leading arm (on which your head should rest) is dropping way too much. It should stay in the extended position until your head is back in the water to reduce drag. Example: minute 2:36

Looking more ripped than normal Lionel, looks like the healthy diets working

When you re-test. Will you factor in the fatigue and or freshness that you currently have? I presume you will be ramping up the training and when test next will have additional load and fatigue? Will this effect your baseline re__set?

Ok! Lionel Thanks for sharing. I see one issue that is going to be resolved. Lower half of your body is sinking to much. Please keep videoing under water so we can watch the improvements!!

Are there no 50 m pools ?

You mentioned that you also wanted to find LT1 here Lionel. Did you actually do that? What is your resting lactate? I think you might have started to fast and already missed part of the curve to actually identify LT1, which should be at the first inflection point of the curve

The last 400 being max effort 125bpm is your max hr or near too it ?! Is the whoop accurate without a hr strap ?

Dang Lionel you look shredded and ripped!!! How about a bud on your nutrition and hydration. Plus do you do any strength training as a part of your regular routine?

I really do hope you go back to lactate training. The science is used by world professional cycling teams and some of the best runners, from middle distance to marathons and now triathlon and beyond for a very good scientific reason. Its one part of the marginal gains at the pointy end of endurance sports!!

Is there pontential of you getting faster?

hope you stick with it, make the tests to track progress and program your training... BLA testing is not useless, this just told to everyone that you have swim biomecanichal efficiency problem at hard efforts that limits you producing propulsion in same projection with your exerted effort... ofcourse for any one you basically just need timer and distance and do the pace per distance curve or power per duration curve to basically get the same outcomes of ones physiological status and sport spesific economics and thus make the plans to hone those sport spesific demands.... but its all for nothing if the testing is sprodiatic...

hows your aero testing going?

Lionel, I have a question... how long is this process to becoming a front-pack swimmer.

You ever try keeping that air in the lungs a little long to maintain that buoyancy through your stroke? From under water shot looks like you expel the air (deflate your buoyancy balloons/lungs) too quickly.

If u swim and 800 and a 1500 below LT do you stay below LT?

Body drag/ efficiency trying to overcome that buy swimming more?? Check the feet on the overhead ankles are locked toes pointing down drag drag

lactate is fitness. weak swimmers should focus on technique, its much more efficoent in terms of speed improvement.

interesting -- and, it seems, sound -- analysis on lactate on a developing swimmer. So the key is technique work?

Hmm, honestly looks like you measured LT1, not LT2....But would have been good to see a resting value and then maybe 1 extra "easy" value just to get the baseline set correctly. Edit: just realized he was calculating Dmax, so technically that's neither LT1 or 2!

This test distance was in yard, not meter, right?

Would be curious to see lactate levels if this 6x400 was done in reverse. Meaning do the faster set first, and then slower with each repeating 400.

Dude....Lactate doesn't matter unless you fix your stroke. 80% drills

lt2 to 2 mmol? And what happens with lt1? Where is lt1?

Chill people … he is working on technique …He’s taking a baseline , working on technique then going to compare

Should you also be finding a threshold level while wearing a wetsuit? Otherwise training may not correlate with race pacing. Then again, you can’t train how swim drafting will affect your LT…

If you get frustrated and want to go back out on your own, say these over in your head, "As an athlete you have to be coachable, and being coachable is a humbling thing."

I know a guy who can help you get to another level.. take him as swim partner 👌🏼 and you’ll see the difference.

Why don’t you just swim more open water, if you feel you’re not fast enough in an open water race?

Honestly you should simply learn & train the basics. 2:30 to 2:40 is horrible to watch. Most 14yo kids in my club swim better and faster than that. Considering they have probably les than half your muscle and heart capacity I think improving your technic is the best and probably only way to get a breaktrough. A guy in his 30's in my club swim around 10k per week max and do only technical sessions. He swims 1:10/100m endurance. He does butterfly, swims drills, one arm crawl etc... He made 4th in his first Iron Man quebec 3 years ago. Swim is definetely different than running and cycling. Simple opinion.

you need trechnique work not lactate testing

LT1 IS AROUND 2 + OR - 0.5 AND LT2 IS AROUND 4 + OR - 0.5. I AM SUPRISE TO SEE LT2 AT 2 ON YOUR CHART ???

Just going to say this,,,the elevation view says it all, the view where I am looking directly down on your stoke, kinda looks like a turtle, that's hurt, no glide at all, it's like this, you think wind tunnel is going to make you faster on the bike,,,well water is like way more finicky then wind, so you really need to find someone like me, because what you are practicing, is all wrong, the more you swim like this, the worst you will be, it's a golfer who's sing is off, no matter how much you practice, it must be correct, or it's a waste off time,

where is this pool??

Comparing pro endurance athlete to us mere mortals can be seen with his average HR

No clue how anyone uses those form goggles. Visibility is garbage! Like looking through two coke bottles. Worst goggles I’ve ever used

🤔pool

Elite swimming for most age groupers… think about this swim data when you think of Lionel as someone who sucks at swimming. Yes, it’s relative to pro’s… But most people who watch probably think he is shit.

OK - to keep banging on a drum: to swim in the ‘Ditlev’ pack in a PTO or 70.3 Chmapionship race you need to swim at that target pace in training - for long reps - consistently (ie. once a week). You have done this before - 1:15 minutes per 100M for 1500M (long course pool) back before covid. You are correct - at this stage in the season physiological metrics are irrelevant (ie. I would NOT care if your lactate was 10, so long as you were hitting you pace marks because - as one of the fittest people on the planet - once your body adapts to the biometrics of swimming ‘fast’ (by Triathlon standards, which is still very very slow by swimming standards), your physiology will catch up rapidly. Even at this early stage in the season, you could do a lot worse than incorporating the following session in to your weekly routine (this the the key session that turned Aussie Pro Chris Kemp into a 3rd pack - 27 minute swimmer - into a front pack - 23 minute swimming at 70.3 races a decade ago [and in only a matter of months]: Main set: 8 x 100M on 1:15 pace (start off with a 2 minute /100M repeat cycle, but decrease this with increases in fitness over time]; 200M swim down; followed by 4 x 200M on 2:30 (so holding your target 1:15M/100M pace); 200M cool down; followed by 2 x 400M on 5 minutes. Given that lactate test, you may well end to increase the interval time, or the recovery time between each of these three components that comprise the main set. But remember, this set is not about being ‘hard’ or ‘threshold’ (although it will hurt). This is about speed: sustained target race pace speed. Also do this session in a long course pool. I know there is one in your home town!

More time wasted. Use the stopwatch. Forget the lactate

No offence, but why not spend the time having swim lessons

Triathlon Inc has failed its athlete development... The Norwegians have surpassed Tri Inc

And no, power is above the water,,,like hitting or spiking a volleyball, or even hitting a golf ball, lol you are being taught all wrong

Lots of drag and swimming with strength not technique.

Again.... too much talk.

Jesus, his LT2 heart rate is significantly lower than my easy heart rate lol
