One person reads this, and it is the same person who writes the calculators.
I read everything. I answer most things within a few days.
What is worth writing about
- A calculator giving a wrong or strange answer. Please include the numbers you entered — it makes the problem findable in minutes instead of hours.
- A factual correction. If something on this site is wrong, I would rather hear it from you than leave it up.
- A calculator you want that does not exist yet. Most of the tools here started as a question a client asked more than once.
Coaching
Online coaching runs through FitActo, not through this site. I take a small number of clients at a time, mostly people with full-time jobs and limited training time.
One thing to know before writing: I do not work with anyone who has active red flags — acute pain, numbness down the leg, or sciatic pain — without a doctor's assessment first. That is a professional ethics requirement, not a preference.
What I cannot do by email
I cannot give you individual medical advice, diagnose an injury, or tell you whether a specific protocol is safe for a specific medical condition. Those need a doctor who can examine you, and no amount of detail in an email substitutes for that.
