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.

    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 ?

    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!!

  • @wod-science

    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!

    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

    @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.

    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).

    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?
