Health disclaimer
I am a hobby athlete, not a medical professional. Everything here reflects my personal experience and my reading of published studies. It is not medical advice, diagnosis or treatment. Talk to your doctor before you change your training, diet, supplements or medication, especially if you have heart, blood pressure, joint or metabolic conditions.
Short version at the top of health articles:
Note: I am not a doctor. This article reflects my personal experience and my reading of the studies listed under References. It is not medical advice. Discuss health decisions with your doctor.
Sources
Health claims link to primary sources (peer-reviewed studies, guidelines, WHO, ACSM, ESC and similar). I separate my own data from published evidence and name the study type and its limits.
Use of AI
I use AI tools for research, structure and language editing. I review, correct and approve the articles myself; experience, test data and opinions are mine. I do not publish unchecked, machine-generated texts or translations.
Independence and affiliate links
I work with affiliate partners. Sometimes I receive devices to test, sometimes I buy them myself. Affiliate links are marked. They do not influence the rating.
Corrections
Every article carries a publication and an update date. Material changes are logged. Please report errors to ulf@conversionloop.net.
Translations
The blog is published in German at harder-better-faster-stronger.de and in English at getrow.ing. Both versions are adapted separately and can differ from each other.
