Stuff you knew about your heart rate but probably forgot during your last ride.

Adhering too strictly to a single intensity parameter can quickly backfire. Because intensity zones shift with increased duration.

6x10 min threshold x2 every week. 12x3x30/15 HIIT on Wednesdays Fast-paced 3h group ride in the weekend. Lifting heavy weights x2 per week. You’re in your 50s, busy job and a family. And you wonder why you don’t progress. You’re doing WAY more intensity than you’re able to adapt to!!!😵

Curious to see that elite coaches behind nearly 400 international championship medals prescribe mostly zone 1 training. Not zone 2. Is it a sport-specific issue? Is it an overlap of zones? The vast energy cost of the W pros produce close to VT1?

It feels pointless posting about cycling as if all is normal this week. Yet, a few things restore my faith in humanity: - the action of the good people of Vermont - the rallying of European leaders and 🇨🇦 - Haltbakk Bunkers acting on their outrage Don’t say..

Experiment and learn your response! Another paper on zone 2 training that neatly demonstrates the great variety in responses of differen intensity markers. In my opinion, yet another reminder for why you shouldn’t rely on one intensity marker (or generic %HR or %FTP ranges).

A viable metod for increasing your time at high % of VO2 max? (-> possibly drive increased performance adaptation). science.wattkg.com/posts/decrea...

Workout Instructions: Decreasing High Intensity Intervals
These instructions may give you more time above 90% of VO2 max during HIIT sessions. Which has been shown to correlate with greater power development.

Vaccari et al. tested 3 interval formats. How much time did each produce at more than 90% of VO2 max ( )? • Decreasing intervals (312 sec) • 3 min intervals (179 sec) • 30 sec intervals (183 sec) Here’s the decreasing interval session. science.wattkg.com/posts/decrea...

What do airline pilots, surgeons and lawyers have in common? Demanding jobs with big work hours -> limited time for training. And shift work doesn’t help. In this scenario, a small shift in mindset can make training that much more enjoyable. And greatly impact how much your fitness develops..👇🏻
