Thank you very much for sharing this valuable information. I believe there are some differences when upper body strength training is followed by endurance training, isn't there?

How would you advise someone with an impared ejection fraction of 35% to train or to assess capacity or physical effort....Or who should i be seaking out to point me in the right direction. Thanks Dan

Thought this was super actionable stuff. Thanks!

Bronek was the perfect choice 💪💪💪

Amazing content!

Great video, right up my alley. I keep seeing more about hyrox and even a girl I know just did the world championships. Seems like it really suits my strengths, I'd like to try it if they ever have an event in Calgary or Edmonton.

Hi! If I have someone who doesn't know their FTP on the bike or their pace for a 10 km run, what would you recommend using to set the intensities for the 5-1-5 test? Because I haven't found material that explains this aspect comprehensively.

really like your videos. very good balance between explaining things on a very understandable level and giving interesting background information. great job. keep it up!

What if ur on gear?

Thank you for another valuable video. Could you explain what threshold is mentioned in the intervals you propose? Is it about the lactate threshold? In what heart rate zones should training below this threshold take place?

I have that same Hstl Made shirt. 🎉 #hstlmade #wedontquit. You’re an absolute legend.✅ @teamRICHEY

Is it possible not to be significantly biased to either category? What to do in that situation - train both intervals protocols, or train a third protocol that is neither?

Great work! Keep it up

Take Tia Toomey and Haley Adams and test it.

God bless you coach , thanks for the updates and the amazing information

Awesome work! Thanks for the video! 🙏 Just a small mistake: My 5-1-5 test was on the C2 Bike (390 Watts), but I've done the same on the Echo Bike up until 425 with the same result, so it doesn't make a difference. Last week I've done 1000 Cals @250 Watts on the Echo Bike with no change in SmO2 after a small initial drop. 🫠 It looked like zone 2, but heart rate and RPE told a different story. I'll keep on sprinting. Thanks, Gommaar!

Awesome work. You've really made it easy to understand. Thank you!

I recently found your channel and I must say I really like all the information, especially being a crossfitter myself. I have a question out of curiosity since I think I’m just like you delivery-limited. I was always told that in this case the best way to improve is long endurance zone 2 training instead of doing intervals. Are there more advantages regarding your protocols compared to this zone 2 training or would you consider them equally important? Keep up the good videos!!

Did you get to 600?

Honestly when i was suggested this channel, I did not think it was going to contain actual science. Love it!

16:40 is this all out from the begging or some high wattage that I can barely sustain for 20 min?

What about DFA alpha 1? Looks like you can measure AeT with hr monitor with it. Athletes with AeT close to AnT are utilization limited

Crossfit would be alot better and more popular without the exercises like handstands and double unders.. and focused more on things that more people can do without learning complex skills

I agree with all of this except the arhlete size. If you look at this years croasfit semifinals it was an advantage if you were a taller athlete. The programming suited taller athletes.

Very interesting video, thank you, (and I’ve subscribed), I do agree in general with the data you present, but for myself as a 170cm / 78kg athlete, I’m definitely on the short side, but as I come from an endurance running and swimming background I find I’m way better at Hyrox as I can hold a high output for a long time, whereas I just can’t lift heavy enough to excel at CrossFit. It is very interesting looking at the similarities and differences between the two sports. Your video was very informative thank you.

We see these hybrid athletes all the time. Nothing new

@CrossFit should use a HYROX event as one of the prerequisites to make it to the Games

I do CrossFit 7-8 times a week (1 being a 5K run) - I find 23H of rest/recovery between every session is perfect for me. My coach is not happy though LOL. I'm very happy to stay consistent, which is my goal as I age (I'm 46)... I'm not here to compete or go to the Games ;-) PS: I actually took my first day off training yesterday after a 55 days streak!

Did you say that running is more suited to taller athletes??

Unfortunately too many mistakes in the video with the Karen/Fran switch-up. It is supposed to be a scientific approach but saying the wrong thing just doesn’t work. If you spot a big mistake like this in your editing, you do a retake.

Do you have any videos on studies comparing injury rate and prevalence across different sports including cf ?

very interesting information, thank you!

lovely working hours, from 9am tot 4:30pm AND time for a workout. In my mind it would make sense to alternate timing from day to day to shift focus between strength and endurance.

@wod-science: What is the correlation between lactate koncentration and H+ concentration? It seems like ppl are generally talking about lactate as something negative to muscle endurance due to the fact that higher lactate = higher H+. I never hear ppl talk about lactate recyling (glucos).

First time I see this Channel! This is an amazing video very informative. 66 yo Master CrossFitter. I’d love to participate to an Hyrox.

Fascinating. I’m curious if lactate threshold, zone 2, or HIIT may be the best way to improve capillary density. Also if having a higher capillarity density lowers the strength recovery time (as in minutes needed to recover between sets). I imagine that may be the case as byproducts may be cleared faster with more blood flow

I have 10 years of CrossFit experience, 40 years old, and typically practice CrossFit 5-6 times per week - over 250 sessions per year. I don't go 110% every session but I almost never sandbag. I find I get more out of the 5 sessions/week consistency than I did when I did less sessions per week. My body is more accustomed to the volume and I get less sore and fatigued when my training is consistent. I think a good indication of how often we should train is from HQ's programming - 3 days on, 1 day off. That's 273 sessions per year.

Would be great to see injury related to the sport and how to come back. Such as like a Disc Hernation,Golfers Elbow etc etc.

I tried to tell most of the people in my community the same thing. But they never seem to care. Hit a WOD straight into a WL session everyday. No prioritizing cooldown 😅

Good video. A few questions though: - where does the timing of protein intake come into recovery for intense workouts? Why is the focus only on carbs? - even though CrossFit workouts are basically always intense, the muscle groups biased each day usually change between each subsequent workout (for example, chest / bench press dominant one day, squat / lower body focus the next day). So does your graph mapping out recovery / performance take that into account? Or does it assume you’re doing workouts focusing on similar muscle groups each day?

Kinda feel my Recovery is just on that 24-48hrs Window for i started programming my training with METCONS - i stuck with a Split Training from my BB Times, where i was able to recover only in 72 Hours or more ... CF Style training def improved some aspects... But i kinda feel my burnout for Deload Days or Weeks highly increased .... or Maybe i just gettin older? - Is there a way to track recovery better than just "asking the athlete" or redo a Session and watch the results??

first tip...actually do a single rep...not head hits...use blocks to create a deficit and then dont kip ur whole body weight turning it into negatives from the first rep...completely understandable if it was a few negatives after momentary muscle failure of course...cross fit is the only training ive evervseen where they teach u the right wsy on how to not use muscle...also side note hands are very wide...are u intentionally trying to reduce rom? i wudnt suggest thst

Is there any evidence to support the statement that age affects recovery?

Hello, i have one question. What is exacly "Crossfit purpose"? I know, that skill will be something about RMU, HSWalkd... Strength some strict movements and more, but i dont know what do you mean with purpose CrossFit. Thanks a lot! Nice video btw

Hyrox is running. CF is physical fitness

Good video, thanks! Who bit your left arm??

CF is a FITNESS program . . . not a sport. HYROX is a sport.

Rich Froning was mentioned that his VO2max was increasing from 50 to 70ml/kg as he begin with Crossfit. How is this corelate with your study?

🙏🙏💪
