      Yeah everyone is different. I can run a fast 3-5km, I can also run a slow 3-5km, and the insane thing is the slow 3-5km will leave a burn in my muscles for longer, that takes me longer to recover from.
      I've tried training my slower running by increasing slow runs, but this just resulted in my calves being completely fucked and my overall running suffered.
      So I stead now I do mostly fast paced running and instead on recovery days I take 1h+ bicycle rides.

    From Norway: 4x4 stems from professors Helgerud and Hoff, advocating it for the general population and athletes. It gave 13% in 8 weeks with 3 training per week in one study, but can give less. It is not used by Ingebritsen or Warholm. The “Norwegian method” is the Marius Bakken approach, far different.

      this is for advanced/professional athletes. It’s fine to do intervals for lower times. You can adapt the interval training per your fitness level. However If you are gassed after warm up, you ran way too hard, during warm up your heart rate should definitely be below 150.

      Hey quick question , i just started running so im a newbie , all i do rn is just run 5k’s the fastest i can. so i run for around 40min total with warmup. How could a 8x5 at my 5k pace with break benefit me?

    • @sertito
      @sertito Před 7 měsíci

      @@adrien2799 you should prioritize slow running as your total work out volume then trying to run 5k all out. Start to target long runs around 4-6 miles in one session. You'll see a lot of benefits. The idea of threshold running as the 8x5 minute runs is to build a more substantial tempo when you actually go and do a race. As a newbie run I would recommend one per month of that workout and concentrate on building your base running, i.e. long slow distance (LSD). After I got two hours of LSD I got a lot faster, needed less recovery and I was able to give more output on my runs. Now I'm not saying just jump into two hours off the bat. Take it easy start at 40 minutes and increase very slowly. Circle back to the 8x5min it's really to help keep that faster pace and even faster pace more steady and for longer times. You probably and this is me guessing your 5k you start fast and slow down a lot at the end. The workout is aimed to keep you at the same pace the whole race or even get negative splits at every km marker.

    • @why8308
      @why8308 Před 6 měsíci

      ⁠@@adrien2799having a break reduces the risk of injury, and also allows you to run at that pace for longer (40 minutes of 5k race pace not including warm up vs around 20-30 minutes not including warm up). Time trialing a 5k as fast as you can every day will not only be less efficient training wise, but also can have a serious risk of injury. I recommend a schedule of:
      Monday - intervals
      Tuesday - easy/slow/short run
      Wednesday - light workout (ex tempo runs)
      Thursday- easy run
      Friday - intervals

    The Norwegian training method is predicated on running higher volume by spending more time running at threshold & sub threshold paces to minimize fatigue & strain from workouts. Occasionally dipping into VO2 max work. Also where is this 13% improvement number coming from?

    • @beansandrunning
      @beansandrunning Před měsícem +6

      There was a study like ten years ago, where this increased the vo2 max for the runners I believe. Göran Winblad has a good reaction on this video, where he debunks a lot of the youtube running myths. Other than this not being the norwegian method, he also talks about how 13% can be achieved with almost every type of workout as a beginner and that this is also a fast way to get injured for a lot of runners😅
      Too be fair I have 4times 800m "sprints" in my training plan, so I dont fully disagree with this kind of workout. Two times a week however is a really bad idea, focusing on more volume and slow runs will be way more beneficial for most runners.

Im pretty new to the science based work outs so please correct me if I'm wrong there. Currently im exercising more to improve my fight training. My lungs are whats causing the biggest problem. During BJJ I know my arms, legs ect can still go for ALOT longer, but my lungs just wanna give up. Im trying different breathing techniques, incorporating more cardio, and have quit smoking tobacco. Im on vape currently (not really better, I know) and slowly making the switch to the new zyn/tobacco free nicotine stuff. I dont wanna hit a hard walk in that and jusy stay on the vape, despite its made me feel so much better than actual smoke. Thanks for the advice!

    Having done some thousand kilometres with this protocol and read all the status about it then improvement is 2% per training.

    This is the same concept for weight training. Except its for the heart muscle.

    And now I'm must search the meaning of VO2 Max😂

  • @sneed777
    @sneed777 Před měsícem

    Any intervals 3-8 mins long will increase v02 max

  • @JackOfAllWeights
    @JackOfAllWeights Před 3 měsíci

    Science from the same research group also found out that only doing 1 block of 4 min at 90% increased your VO2 max with 10%…

    • @M_TELEDO1212
      @M_TELEDO1212 Před 6 měsíci

      My advice, don't bother with fitbit. It's consistently 20 bpm off during high intensity exercises. Apple is inaccurate too but less so. Never tested a Garmin or other brands of sport watches. Most accurate I've found is the heart monitor that straps to your chest.
