Interval training is a great way to improve your overall conditioning in a short period of time. But there are many types of interval training, each with a different training effect. In this video I lay out how to detect WHAT is limiting your conditioning (the heart and/or the muscle) and how to train according to your limitation.

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

Sometimes, just sometimes you have to respect the algorithm :). Glad you like the content.
Really cool scientific approach on that topic! As a delivery limited guy, how much work would you do weekly in the threshold domain and how much above? Maybe in percentage regarding time or sessions ?
Bronek was the perfect choice 💪💪💪
Amazing video, nice value that can be taken out of it. Keep it up, all the best
Awesome work. You've really made it easy to understand. Thank you!

Amazing video! Learnt a lot. I’m probably a utilization limited person so will try your suggested training method.

Yes. sprint interval training is hard, but necessary for many athletes. Glad you liked it.
Great work! Keep it up

Thank you, your information is great for coaches, who actually want to develop a system and testing for training functional fitness/crossfit athletes.

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!!

Excellent question. I have a video lined up to tackle exactly this question. Stay tuned. TLDR - power athletes who really struggle with conditioning could do long intervals AND zone 2.
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!

Interesting stuff. Try hyrox maybe? Might be a great sport for your profile.

@@wod-science But I hate running... 🤣 Air Bike Hyrox would be nice.
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?
@wod-science
13 күн бұрын
Threshold would be the intensity that you could hold for 35-40 min without dropping off in pace. A good rule of thumb is the average of a 20-min all out time trial and then taking 95% of that value (in watts). This value is FTP. Basically lactate threshold yes. In our endurance programs we take 100-105% of FTP to start for our intervals (for instance 4 x 4 with 2 min rest)

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.

Just start very light. 90W and go up by 30W.
16:40 is this all out from the begging or some high wattage that I can barely sustain for 20 min?
@wod-science
15 күн бұрын
The latter. Start high, but sustainable and hold on for 20 min. Bonus points if you tape the screen, so you can only see the time (not pace).
I find it difficult to determine what type of athlete I am most similar to. I think I swim around in some sort of gray area. I am very average in both strength and endurance.

Absolutely not to worry. For CrossFit or other hybrid sports, I actually think that is the best starting point as you can improve both at the same time!
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

HI Dan, cannot give you that specific advice. I would ask a physician who specializes in heart function and do an exercise test in his/her laboratory.

Thanks I'll bring that up on next consultation
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?
@wod-science

Yes, I suggest polarized training. Combination of HIT and Zone 2 training.
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

Did not know this and had to look this up. Not familiar with it. Will do reseach and maybe post a video on DFA Alpha in a couple weeks. Thanks for the tip.
