It’s pretty easy to be mislead in 2025 with people espousing advice left right and centre.
It’s probably better to mute them and watch rather than listen 😉

To try better understand, quantify and codify how much discomfort we need in health and performance I developed the concept of “The Window of Progress”

Hint; it’s not ALWAYS about being uncomfortable and how uncomfortable matters!

@thescienceofsport.bsky.social heard you mention you have no control over your ads, assuming you at least allowed them to be inserted & are remunerated as a result? If not let me know and I’ll talk you through changing platforms - think Spotify is probably superior to host anyway
